fixed : Canon scanner error -21345 on M1 Mac

Question :

I have have just upgraded to a new MacBook Air M1 2020 (with an Apple M1 processor) running macOS 11.0 Big_Sur. Now, I am trying to get my Canon PIXMA MG3250 All-in-one printer-scanner to work with it… but even though I can get the printer function to work, when I want it to scan I get an error…

Installing the Canon MG3250 through System Preferecens > Printers & Scanners > Add Printer was really simple as it was immediately seen through Bonjour. After installing, the MG3250’s icon is listed on the left, and when I click it, the window opens where I can choose either the “Print” or the “Scan” tab. After choosing the later, I get the “Open scanner”-button, and when I click that, the built-in macOS scanner-app opens the “Scanner” window… which gives this error : “Failed to open a connection to the device (-121345)” each time I try. I just can’t get it to work.

What is wrong ?

Answer :

When you get this error in this setup, you will probably have gotten an error saying “IJScanner3” also. Do this to fix it :

  • goto the Canon UK website : https://www.canon.co.uk
  • there, browse to the PIXMA MG3250’s Driver Support-page or go there directly using this link : https://www.canon.co.uk/support/consumer_products/products/fax__multifunctionals/inkjet/pixma_mg_series/pixma_mg3250.html?type=drivers&language=en&os=macos%2010.15%20(catalina)
    • Yes, that’s right, even though you are running macOS 11.0 Big_Sur and Canon tells you there is no driver for such an advanced OS, the macOS 10.15 Catalina driver still works
  • when you see the ICA Driver Ver. 4.0.0a (Mac) version listed, click the blue download button to download
  • in your downloads folder, you will now find a file called miss-mac-ijscanner3-4_0_0-ea19_2.dmg
  • click that file and it will mount an installer called Canon IJScanner3_040000.pkg
  • click that file and the 2020-version of the scanner driver will be installed
  • when done, make sure the System Preferences are closed
  • then open System Preferences > Printers & Scanners > MG3250 again and click the “Open Scanner”-button
  • now, the built-in scanner-app will open the Scanner-window again, but hits time without the error… so you are good to go !

That’s it !

fixed : delete an old TimeMachine-backup file from a Time Capsule

Question :

I’ve bought a new MacBook and I want to use my existing Time Capsule for it’s TimeMachine-backups, but it’s full. The backup-file, a .sparsebundle-file, from my previous MacBook that I am going to pass on to one of my children, is far too big.

I have installed my new MacBook from the old MacBook’s TimeMachine-backup, so I am not needing that backup again, but I want to make two new TimeMachine-backups as soon as possible : one for my new MacBook and one for the old MacBook right after my child starts using it.

But, I can’t seem to delete the old .sparsebundle-file from my Time Capsule completely… I’ve done several attempts, but I keep running into the same error message “The operation can’t be completed because some items had to be skipped. For each item, choose File > get Info, make sure “Locked” is deselected, and then check the Sharing & Permissions section. When you are sure the items are unlocked and not designated as Read Only or No Access, try again.”. On first sight, the .sparsebundle-file is still there. On further inspection, it turns out the the .sparsebundle-file has shrunken in size.

But… what can I do to completely delete the old .sparsebundle-file ?

 

Answer :

This problem can occur especially with bigger and older .sparsebundle-TimeMachine-backup-files. Note that the really new TimeMachine-backup-files have a .backupbundle-extension, not a .sparsebundle-extension, but there is hardly any difference

To be able to delete the old .sparsebundle-file, start by doing this :

  1. connect your new MacBook to the Time Capsule using a UTP/Ethernet-cable
    • make sure to shut off AirPort/WiFi on your MacBook :
      • in the top menu-bar, click on the AirPort/WiFi-icon (the piece of pie)
      • in the pulldown-menu, set the WiFi-slider to OFF
    • if you do not have an Ethernet-port or a USB-to-Ethernet-converter on your MacBook :
      • connect your MacBook to the Time Capsule using AirPort/WiFi
      • but make sure to disconnect all other AirPort/WiFi-connected devices
  2. Make sure that your Time Capsule has the latest firmware installed :
    • goto Applications > Utilities > AirPort Utility
    • open AirPort Utility
    • in the AirPortUtility-window, click on your Time Capsule’s picture
    • when prompted, enter the Time Capsule’s password
    • in the popup-window, at ‘version’ check if there is an update available
    • if so, click on the button to install it
    • if just the version number is shown, you already have the latest firmware installed, so you don’t need to do anything extra here
    • exit AirPort Utility
  3. Make sure that you have read&write-privileges on the .sparsbundle-file you want to remove :
    • right-click ( CTRL-click ) on the Finder-icon (blue-grey face icon) in the far left of the Dock
    • from the popup-list, select New Finder Window
    • scroll down to the “Locations” group in the menu list at the left and click on “Network”
    • in the window that opens, goto Network > Time Capsule
      • if you have multiple Time Capsule devices, make sure you select the Time Capsule that the .sparsebundle-file you want to delete is actually on
    • if it says “Not Connected” click the “Connect as”-button and typ the Time Capsule’s password
    • if it says “Connected”, you’re good
    • open the Data folder and right-click ( CTRL-click ) on the TimeMachine-backup-file you want to delete
    • from the popup-menu, choose Get Info
    • in the Get Info window that opens, choose these settings :
      • uncheck the check-box at “Locked” (so the file is unlocked, i.e. delete-able)
      • uncheck the check-box at “Hide extension” (so the .sparsebundle extension will be visible in the file name)
      • at “Sharing & Permissions” set Privilege for “everyone” to “Read & Write”
    • close the Get Info window

Having set the above, there are various options that might enable you to delete the old .sparsebundle-file (or .backupbundle-file). Your options are listed below, from simple to extreme. Read all of them before starting, and choose the option you want to try first. Any of these might be successful, and if the one you chose first doesn’t work, just try another one.

Option #1 : delete the .sparsebundle-file from within the Finder

  • goto Finder > New Finder Window
  • goto Locations > Network > Network > Time Capsule > Data
  • right-click ( CTRL-click ) on the .sparsebundle-file you want to delete
  • from the popup-list, select “Move to Bin”
  • wait for the “Move to Bin” action to complete
  • if it doesn’t end in an error, empty the bin/trash (and you’re done)
  • if this ends in an error, try any of the other options

Option #2a : additional TC reset

  • restart your Time Capsule by unplugging the power cable for 30 seconds
  • plug the power cable back into the Time Capsule
  • when the Time Capsule comes back online, follow the directions from Option #1

Option #2b : additional Mac reset

  • shut down your Time Capsule by unplugging the power cable (for 30 seconds)
  • shut down your MacBook by selecting Shut Down from the Apple-menu top-left
  • plug the power cable back into the Time Capsule
  • restart your MacBook by pressing the power button
  • when both your Time Capsule and your MacBook have restarted, follow the directions from Option #1

Option #2c : additionally disconnect other devices

  • shut down your Time Capsule by unplugging the power cable (for 30 seconds)
  • now, disconnect all UTP/Ethernet-cables leading to other devices than your MacBook (you can even disconnect the cable connected to your internet modem-router)
  • shut down your MacBook by selecting Shut Down from the Apple-menu top-left
  • plug the power cable back into the Time Capsule
  • restart your MacBook by pressing the power button
  • when both your Time Capsule and you MacBook have restarted, goto Applications > Utilities > AirPort Utility
  • in the AirPort Utility window, click on the picture of your Time Capsule, typ your password if needed and check which devices are connected
  • then, one-by-one go to each device listed and shut down it’s WiFi-connection
  • when done, close the AirPort Utility application and reopen it
  • again, in the AirPort Utility window, click on the picture of your Time Capsule, typ your password if needed and check which devices are connected
  • you should now see no devices listed at “wireless clients” (except for your MacBook if you aren’t able to connect it using a UTP/Ethernet-cable)
  • then, follow the directions from Option #1
  • NOTE : do not forget to plug all UTP/Ethernet-cables back into your Time Capsule and switch on WiFi on all devices that were previously connected

Option #3 : by backing up the Time Capsule content

  • NOTE : you will need a Mac-connectable external USB-harddisk for this ! (at least as many GBs as the internal HD of your Time Capsule, so 500G, 1TB, 2TB, 3TB of larger)
    • to check if the USB-harddisk is Mac-connectable, plug it into your Mac and if it pops up you’re okay
    • if it doesn’t show up, it’s a Windows NTFS-disk that needs to be reformatted to Mac Journailed format ( note that this erases all content, so ONLY reformat it if it’s an empty brand-new external harddisk ! )
  • NOTE : this method will work 99% of the time, but it will probably take (far) more time than any other method
  • start by connecting the external USB-harddisk to your Time Capsule’s USB-port
  • then, on your MacBook, goto Finder > New Finder Window
  • then, in the top menu-bar, goto Finder > Preferences
  • in the Finder Preferences window, click the Sidebar tab
  • in the list that shows up, make sure that “External disks” and “Connected servers” are checked
  • then close the Finder Preferences window
  • now select the New Finder Window you had just opened
  • goto Locations > Network > Network > Time Capsule
  • next to the Data-folder, there is now a new folder named after your externe USB-harddisk
    • for the following, assume that your extern USB-harddisk folder is simply called “usb-HD”
  • goto Locations > Network > Network > Time Capsule > usb-HD
    • if the “usb-HD” folder is completely empty, you’re okay
    • else, click on the “More” icon (the circle with 3 dot in it) and in the dropdown menu click “New Folder” and call it “TC-backup”
  • goto Locations > Network > Network > Time Capsule > Data
  • inside the Data-folder select all files (both backup-files and other files) that you DO NOT want to delete
  • drag&drop all the files into Locations > Network > Network > Time Capsule > usb-HD
    • it may take some time for all files to copy over, so let it run
    • if you run into an error, try copying over every file one-by-one
    • if you still run into an error, just try again
  • when all files are copied over, you can unplug the external USB-harddisk from your Time Capsule
    • as an extra safety precaution, you can unplug the power cable from your Time Capsule before you unplug the USB-cable and replug the power cable when the external USB-harddisk is disconnected
  • then goto Applications > Utilities > AirPort Utility
  • open AirPort Utility
  • in the AirPortUtility-window, click on your Time Capsule’s picture
  • when prompted, enter the Time Capsule’s password
  • in the popup-window, click the Edit-button
  • in the window that opens, select the “Disks”-tab
  • in the Disks window, click the “Erase Disk”-button
  • next, choose the level of security for the erase (“Quick Erase” should do fine, since you are going to use the disk for the same purpose immediately afterwards)
  • then click “Update” and the Time Capsule’s status light wil flash orange-yellow until the disk is erased and the Time Capsule is accessible again
  • then, exit AirPort Utility
  • goto Locations > Network > Network > Time Capsule > usb-HD or Locations > Network > Network > Time Capsule > usb-HD > TC-backup (depending on where you put your Time Capsule back-up files)
    • if you don’t see the “usb-HD” folder, make sure your external USB-harddisk is plugged back into your Time Capsule
  • now, select all files from the back-up folder (either “usb-HD” or the “TC-backup” folder within it)
  • drag&drop all the files into Locations > Network > Network > Time Capsule > Data
    • it may take some time for all files to copy over, so let it run
    • if you run into an error, try copying over every file one-by-one
    • if you still run into an error, just try again
  • when the copying is finished, you should now have your Time Capsule the way you wanted it : exactly the same (backup) files on it’s disk, but without the .sparsebundle(s) you don’t need anymore

Option #4 : manually deleting all files inside

  • goto Finder > New Finder Window
  • goto Locations > Network > Network > Time Capsule > Data
  • right-click ( CTRL-click ) on the .sparsebundle-file you want to delete
  • from the popup-list, select “Open Package Content”
  • in the Finder window that opens click on the “bands” folder
    • if the “bands” folder appears empty, just wait a few moments for its content to appear in the Finder window
  • SHIFT-click on the top file and scroll down to select multiple files, then press the Backspace-button on your keyboard to delete them
    • you are able to select and delete up to 8000 files per batch (according to user ‘cmaryg’)
    • if a batch refuses to delete at the first attempt, just try again – usually it will eventually be deleted anyway (according to user ‘cmaryg’)
    • if a batch refuses to delete after a few attempts, reduce the number of files in it by selecting less files at once and try deleting again
    • if you happen to run into a single file that refuses to delete, do this :
      • right-click ( CTRL-click ) on the file
      • from the popup-list, select “Get Info”
      • in the window that opens, make sure that there is no checkmark at “Locked”
      • then try deleting the file again
  • then repeat this for the next batch of files, until the “bands” folder is completely empty
  • if the “bands” file is completely empty, close the Finder window that displays the “bands” folder
  • then, goto Finder > New Finder Window
  • goto Locations > Network > Network > Time Capsule > Data
  • right-click ( CTRL-click ) on the .sparsebundle-file you want to delete
  • from the popup-list, select “Move to Bin”
  • if it doesn’t end in an error, empty the bin/trash (and you’re done)
  • if this ends in an error, you can still try Option #3, but probably this will help too :
    • goto Locations > Network > Network > Time Capsule > Data
    • right-click ( CTRL-click ) on the .sparsebundle-file you want to delete
    • from the popup-list, select “Open Package Content”
    • in the Finder window that opens, select the top folder and drag it to the bin (trash)
    • repeat this for all folders listed
    • then, select the top file and drag it to the bin (trash)
    • repeat this for all files
    • if you run into a file that refuses to delete, do this :
      • right-click ( CTRL-click ) on the file
      • from the popup-list, select “Get Info”
      • in the window that opens, make sure that there is no checkmark at “Locked”
      • then try deleting the file again

That should be it !

As mentioned before : the Option #3 method will work (nearly) always, but it’s time-consuming and you will need a lot of extra disk space for it (on an external harddisk).

tips : which affordable display is best for working from home with a MacBook Pro ?

Question :

I need to work from home and I am looking for an affordable display to hook up to my MacBook Pro, to make my work a little easier.

Do you have any recommendations ?

 

Answer :

When buying an external display and having only a few hundred euros of budget*, look at these specs mainly, and decide which order of priority they have in your specific case :

*= this is for people who do not have a budget of โ‚ฌ500 or more

  1. HDMI or DisplayPort :
    • what ports does your MacBook (Air/Pro) have ?
      • if it has USB-C (or Thunderbolt 3) only, get a display with HDMI-input and get a USB-C-to-HDMI-cable that can handle 4K@60Hz
      • if it has a miniDisplayPort (or Thunderbolt 1 or 2) and regular sized USB-ports, get a display with DisplayPort(v1.2)-input and a get a miniDisplayPort-to-DisplayPort-cable
  2. number of pixelsย (is preferrred over screen size) :
    • in any home office or home schooling situation, you will not be more than 60cm away from your screen (note : the front of the screen will be about 10cm in front of the wall, because of the display stand) : so there’s no need for a huge screen :
      • when you are about 40cm from your screen, go for a 21″ to 24″ display
      • when you are about 50cm from your screen, go for a 24″ to 27″ display
    • any display with 1920×1080 (1K/HD) pixelsย or more will do just fine
      • 1920×1080 looks great on 21″ or 24″ 16:9 screen
      • but 1920×1080 looks fuzzy on a 27″ 16:9 screen
      • 2560×1080 looks okay on a 27″ wide screen
      • but 2560×1440 looks great on a 24″ 16:9 screen
  3. IPS display :
    • for home office work or home schooling, get an IPS display – it has better color representation and is easier on the eyes when using it for extended periods (hours and hours of continuous working)
    • for gaming, you might consider getting some other type of display, like TN, that enables you to get higher refresh rates for a tighter budget, but you shouldn’t use those for anything other than gaming
  4. refresh rate :
    • for home office work, a refresh rate of 5ms @60Hz is perfect
    • for gaming, get as close to 1ms @144Hz as your budget can afford (3ms @100Hz or 2ms @75Hz is okay for budget gaming)
  5. adjustable height (and orientation) :
    • because of ergonomics, it is important that you adjust the height to make sure top of the display is at the same height as your eyes when sitting straight up
    • because light reflection on the screen will be extremely annoying, make sure the display has the option to slightly tilt
    • only if you are working on a lot of text documents you will benefit from the option to twist the display’s orientation from landscape (regular) to portrait mode
  6. integrated multi-port USB3-hub :
    • this is an essential ! make sure that there is a USB-multipier in the display and that it’s USB3.0 or USB3.1 based
      • since there aren’t many USB-ports on your MacBook (Air/Pro), you will need extra USB-ports (especially if you have a USB-C MacBook (Air/Pro), since you will need one USB-C port to connect the screen)
      • a USB-port on your screen will enable you to connect a USB3-to-GigabitEthernet-adapter which will outperform your WiFi connection, and your MacBook (Air/Pro) will instantaneously be connected to fast wired internet the moment you connect it to your display
    • 2 extra USB-ports on the Display is the bear minimum : you should prefer 4 or more USB-ports, so you can connect these if you need to :
      • a USB-mouse
      • a USB-keyboard
      • a USB-to-Ethernet adapter (preferably USB3-to-GigabitEthernet)
      • a USB-printer
      • a USB-scanner
      • a USB-flashcardreader (for photo camera memory cards)
      • a USB-to-TV adapter (e.g. an EyeTV stick, to watch picture-in-picture TV)
      • connect or charge your iPhone or iPad
      • an external harddrive or backup drive
    • for a keyboard or mouse (or even a wired joystick/joypad) you don’t really need a USB3.0 or USB3.1 connection, but for data transfer it will save you a lot of time
  7. price :
    • do not go for ‘lowest budget’ if you need to use the display for working from home or home schooling, find a display for โ‚ฌ200 to โ‚ฌ250 : even though you cheaper displays are available, do not buy any display that was under โ‚ฌ200 when released : most of the time, you will be better of getting a slightly older (up to 3 years) display model that used to cost โ‚ฌ300 or more
      • make sure you also take into account the extra headphone, sound system, ethernet-adapter, mouse, keyboard and alike when deciding on your budget for the display
  8. integrated webcam :
    • if you need to do video-conferencing, make sure you get a webcam with your display – an integrated webcam will turn out to be very convenient (an integrated webcam cannot compete with a high-quality webcam, but if you use an external webcam, make sure to get a display with aย USB3-hub with enough ports in your display)
      • added bonus of most integrated webcams is that de webcam is either pop-up or slide-to-open, so you can easily prevent being ‘accidentally’ exposed to webcam viewers
      • make sure the integrated webcam is 1.2 megapixel (1.2MP) or more : the FaceTime HD webcam that is built into a MacBook is at least 1.2MP (in an iPhone X the selfie camera is even 7MP)
  9. integrated microphone :
    • if you have the need for a webcam on your display, make sure you also have a microphone – an integrated microphone will turn out to be very convenient (an integrated microphone cannot compete with a headphone with integrated microphone, a gaming headphone or a separate directional of voice microphone)
  10. integrated speakers :
    • most displays do not have integrated speakers, butย having the option to watch home schooling lessons or YouTube-videos without a headphone are very convenient, even though audio quality of most integrated speakers is okay but not impressive (if you do not already have an audio systemconnected to your MacBook, these integrated speakers might even turn out to be essential)
  11. bezel thickness :
    • the bezel (the edge around the actual screen) is really important if you want to set multiple displays side-by-side, but most of the time it is only a matter of taste in design : about 15mm is okay, especially if the display will be placed in front of a distracting environment (like a window, fancy wallpaper or a hallway)

Note : make sure you also think about these :

  • you need to use an external keyboard and mouse (or trackpad) :
    • any mouse or keyboard that suits you will do, so if you have an old mouse and even keyboard around, use those
      • for work, USB, Bluetooth and RF (wireless connection from a dedicated USB-to-wireless-plug) will all do
      • for gaming, only USB is advisory as any wireless connection might get laggy during intensive use
    • if you need to buy a new keyboard, think about these :
      • get a ‘Designed for Mac’ keyboard with the Mac key-layout, so with a COMMAND/CMD-key (and not a WINDOWS-key : only if you can typ blindly without any restrictions, you can get a Windows-layout keyboard and remap the keys in macOS)
      • get a keyboard that suits your main language : usually that is a QWERTY-layout, but for French it is AZERTY-layout and for German it is QWERTZ-layout (this will also help when you need to use accents in texts)
      • if you need to typ a lot, get a keyboard mechanical keys and spacing between all keys
      • if you need to input a lot of numbers (if you’re in accounting or working with Excell sheets) get a full-size keyboard with an integrated numeric pad (on the right of the keyboard)
      • a keyboard with an integrated trackpad can be beneficial for some, but make sure you get one with a Mac key-layout
      • an ergonomic keyboard can be really beneficial, but there are very few ergonomic keyboards with a Mac key-layout
    • if you need to buy a new mouse, think about these :
      • a mouse with a right and left button and a scroll-option will do for most purposes
        • most people have no need for a fancy gaming mouse with more than these 3 functions
      • consider using a trackball or ergonomic mouse
      • a Bluetooth or RF-wireless mouse does have downsides :
        • it will need to be charged (Apple’s Magic Mouse 2 is problematic in this respect…)
        • it easily gets lost
        • when the battery is down, you will need to open your MacBook and use the built-in trackpad until the mouse is recharged
    • if you need to buy both a new mouse and a new keyboard, have a look at the mouse & keyboard combo offerings by renowned brands like Logitech,
  • make sure your MacBook (Air/Pro) has it’s power adapter plugged in when using an external display, else you cannot use your display with the MacBook’s lid closed and your MacBook will quickly run out of battery
  • if your MacBook has USB-C (Thunderbolt 3) ports, and your Display doesn’t have a built-in multi-port USB3-hub, consider getting a USB-C Docking-hub
  • if your MacBook has regular USB ports, and your Display doesn’t have a built-in multi-port USB3-hub, consider getting yourself an additional USB3-hub
  • if your mouse is on a very reflective surface (like a glass table) or a wobbly surface (like a rustic wooden table), your mouse will not work reliably, so it is advisory to use a mouse mat (or a plastic placemat or even a sturdy-covered magazine)
  • to minimize the clutter of cables, you can use a cable hose to keep your cables together (budget option : use tie-ribs, or even ‘the pieces of plastic covered metal wire’ that you get with nearly every cable or electronic device you buy, to tie your cables together)

fixed : external display goes black when I close my MacBook

Question :

Since I need to work form home at this moment, I have connected an external display. It works great and I now have a far better overview than I had on my tiny MacBook Pro screen. Now I have connected a USB-keyboard and a wireless mouse, so I would like to close my MacBook’s lid while I’m working on the external display. But, somehow, every time I close my MacBook’s lid, the connection to the display is lost and the display goes black…

What is going on ?

 

Answer :

To prevent your battery from draining while you are not using your MacBook, all connections are cut off when the lid is closed (since you cannot access the keyboard or the screen when the lid is closed). This also means that the connection to your external display will be cut off whenever you close your MacBook’s lid.

However : since your MacBook’s battery will no drain as long as extra power is provided, this shut down feature will not be activated as long as your MacBook is plugged into the wall charger. So, there’s your answer : just plug your MacBook into external power, and your external display will not go black when you close the MacBook’s lid.

Note : if you already have your MacBook connected to external power and your external display still goes black, see this post.

That’s it !

fixed : MacBook Pro sighs then hangs during startup without progress bar over and over again

Question :

I have a ย 2018 MacBook Pro 13″ with TouchBar and 4 Thunderbolt3 ports that seems to hang during startup : the MacBook ‘sighs’ (fan noise) during startup and shows only a black screen with a white Apple-logo, but no progress bar as usual… then it automatically restarts… and the same thing repeats itself…

Is there any way to solve this ?

 

Answer :

This might be caused by a hardware problem, so if it happens frequently, you should take your MacBook Pro to an AppleStore or authorized Apple Repair shop for repair.

But before you do so, try this, as it might fix your problem :

If you do see a progress bar during startup, look at this post :

fixed : MacBook Pro hangs during final stage of macOS startup

If you do not see a progress bar during startup, do this :

  • unplug everything else from the USB-C ports
  • now plug in the USB-C power-adapter
  • then, if you can, plug-in a USB-C-to-Ethernet-adapter and make an ethernet-connection to your network (and the Internet), if not leave it
  • then, press the ON/OFF-fingerscan-button (top-right in the Touch Bar) to restart your Mac
  • then, during restart, immediately press the [CMD]+[ALT]+[R] key-combo on your keyboard
  • keep this key-combo pressed for about 30 seconds, then release
  • now, leave your MacBook connected to power and internet overnight
  • in the morning, your MacBook will have reinstalled the latest version of macOS

…and you will be good to go ๐Ÿ˜‰

If the problem persists overnight, you might want to try this also, before you decide to bring in your MacBook Pro for repair :

  • create a macOS installer on a USB-stick (or even a USB-C stick)
    • as your own MacBook Pro is not available for this, you need to do this on another Mac or ask someone to do this for you
    • instructions on doing this can be found here on Apple.com
  • then plug the USB-C stick (or USB-stick with a USB-to-USB-C-adapter) into your MacBook Pro
  • then restart your MacBook Pro, while pressing the [ALT]-key on your keyboard
  • release the [ALT]-key when the Startup Manager window opens
  • then select the USB-stick as your startup disk
  • then follow the onscreen instructions for (re)installing macOS

That’s it !

As mentioned before : if you keep running into this problem frequently, you might have a hardware problem and you should bring your MacBook Pro in for repair.

fixed : how to retrieve Safari Strong Password from iCloud

Question :

I am setting up an app (ToDoist.app in this case) to work across my devices. I have set up the app (ToDoist.app) on my iPhone about a week ago, and now I am trying to set up the app on my Mac. The problem is I need to login to my ToDoist-account on my Mac, but since I have used the password that was automatically suggested I have no recollection of the password I have set…

Is there any way to retrieve the password from iCloud ?

 

Answer :

Yes, there is ๐Ÿ˜‰

To make the actual password visible, do this :

  • make sure that both your iPhone and your Mac are logged in with the same iCloud-account
    • on your iPhone, goto Settings.app > [your name] (listed on top) > iCloud
    • on your Mac, goto System Preferences > Apple ID (grey tile with the white Apple logo, top right)
  • then, make sure that iCloud’s password backup is switched on
    • on your iPhone, in Settings.app > [your name] (listed on top) > iCloud > “Apps using iCloud” > Keychain should be ON
    • on your Mac, in System Preferences > Apple ID > “Apps on this Mac using iCloud” there should be a check-mark at “Keychain”
  • if it wasn’t, restart the app on your iPhone
  • then, on your Mac, goto Safari > Preferences > Passwords
  • then, login on the window that opens ( using your Mac’s screen unlock password )
  • in the next window, scroll down the list and select the appropriate website
  • then, left-click on the dotted-out password ( so the actual password will be shown )
  • then, right-click on the password and select “Copy Password” from the pop-up list
  • now, paste the password into the app’s login-window

…this will unlock the app ๐Ÿ˜‰

enjoy !
