fixed : MacBook’s external monitor screen stays black

Question :

In my office, I am using an external monitor as my main screen for my MacBook Pro. Today, the screen didn’t respond when I connected my MacBook however : the screen stays black and nothing appears on-screen. So I opened up my MacBook and used the built-in screen to figure out what’s wrong, but so far I haven’t found any indication in the Displays Preference Panel that my MacBook even detects the second screen…

What can I do ?

 

Answer :

In such situations you should always do this first :

Remedy #1 :

  • make sure your monitor is switched ON
  • then hit the SPACE-bar on your external keyboard several times (maybe once, usually about 5 to 10 times…)
  • the monitor should now appear and show the inlog panel to unlock your screensaver
  • then login

if this works, you’re good, if not, try Remedy #2

NOTE : if you have a Benq monitor (especially the BL2420TP), try this first :

Remedy #2 :

  • unplug all cables between the monitor and your Mac ( DisplayPort / Thunderbolt / HDMI / DVI / VGA  and also USB, UTP, FireWire and PowerAdapter )
  • shut down your monitor
  • shut down your MacBook
  • reconnect all cables and double-check if they’re properly connected on both the Mac and the monitor
  • switch on your MacBook
  • switch on your monitor

if this works, you’re good, if not, try Remedy #3

Remedy #3 :

  • on your MacBook, open Apple [main menu bar top-left] –> System Preferences
  • in the System Preferences window, select “Displays”
  • in the Display Preferences window, see if there is a button marked “Gather Windows” bottom right
  • if there is no “Gather Windows” button, press the ALT-key on your keyboard and a button marked “Detect Displays” appears ; click on it when it appears

if this works, you’re good, if not, try Remedy #4

Remedy #4 :

  • on your MacBook, open Apple [main menu bar top-left] –> System Preferences
  • in the System Preferences window, select “Displays”
  • in the Display Preferences window, see if there is a button marked “Gather Windows” bottom right
  • if there is a “Gather Windows” button, click on it
  • then you will see 2 Display Preference windows on your MacBook screen
  • select the Display Preference window that has 3 tabs on it marked “Display”, “Arrangement” and “Color” (not the window that has “Display” and “Color” only)
  • first, press the ALT-key on your keyboard and a button marked “Detect Displays” appears where the “Gather Windows”-button used to be ; click on it when it appears
  • if your monitor switches on, you’re good, if not…
  • click on the “Arrangement”-tab and in the next window put a checkmark at “Mirror Display”
  • if your monitor switches on now, uncheck the “Mirror Display” option again and close your MacBook… you should be good now…

if this didn’t work, try Remedy #5

Remedy #5 :

  • unplug all cables between the monitor and your Mac ( DisplayPort / Thunderbolt / HDMI / DVI / VGA  and also USB, UTP, FireWire and PowerAdapter )
  • shut down your monitor
  • shut down your MacBook
  • reconnect your Mac to your monitor using a different type of cable then you normally would choose (e.g. if you normally use a DisplayPort/Thunderbolt-cable, use an HDMI or DVI cable now)
  • switch on your MacBook
  • switch on your monitor
  • if your monitor wakes from sleep now, open Apple –> System Preferences
  • in the System Preferences window, select “Displays”
  • in the Display Preferences window, see if there is a button marked “Gather Windows” bottom right
  • if there is a “Gather Windows” button, click on it
  • then you will see 2 Display Preference windows on your MacBook screen
  • now, remove the monitor-cable that you have just used to connect your MacBook to your monitor
  • then, reconnect your MacBook to your monitor using all cables you normally use to connect the two
  • if your monitor now wakes from sleep, you’re good
  • if it doesn’t, restart your monitor
  • it that doesn’t help, restart your Mac

normally your issue should be resolved by now…

if still the monitor stays showing a back screen, I’m sorry to inform you that your screen probably has a hardware problem… if so, get an authorized Mac-repair-centre to fix it, get the Apple Store support-crew to fix this…

that’s it !

enjoy 😉

fixed : get iOS10-iPhone’s photos on old Snow Leopard OSX10.6.8-Mac

Question :

I just got a new iPhone 7, and now I want to transfer my photos from my previous iPhone 6 onto my MacBook. I was hoping to use iCloud for this, but my MacBook is rather old and can’t run any version of OSX newer than MacOSX 10.6.8 “Snow Leopard” which doesn’t have iCloud installed, just it’s predecessor MobileMe…

What can I do ?

 

Answer :

Theoretically, you could also go online from your Mac and get access to your photos through the iCloud.com website… but since the latest versions of Safari, Chrome and Firefox don’t support MacOSX 10.6.8 any longer (Opera does for now, but that’s about to change also), this route is not a future-proof solution.

The most future-proof solution is using a USB-connection like this :

  • on your Mac, open the Applications-folder and open the Image Capture app
  • now connect your iPhone to your Mac using a USB-cable
  • you will get this error message [ Photos in the Camera Roll on “…” cannot be viewed or imported because the iPhone is locked with a passcode”
  • click on OK
  • then unlock your iPhone with your fingerprint (or type your 6-digit unlock code)
  • on the iPhone you will get this message [ Trust this computer? ]
  • click on Trust
  • then in Image Capture, under Devices, click on iPhone
  • now all the photos on your iPhone will be listed and/or displayed on your Mac
  • from the pulldown list at “Import to:” select a folder to import the photos to (the default folder is your Pictures-folder, but you can also choose iPhoto or create a new folder at “Other…”)
  • then select the individual photos you want to import and click on Import, or click on Import All to import all your iPhone’s photos onto your Mac
  • then wait…

that’s it – enjoy 😉

fixed : “No Volumes Found in backup”-error

Question :

I was trying to get Migration Assistant-app to put all my data on my new Mac, but when I select the sparsebundle backup-file from Time Machine in Migration Assistant, I get an error : “No Volumes Found in backup”.

How can that be ? I’ve made a new TimeMachine-backup just minutes before, and I didn’t get any errors there… what is wrong ?

What can I do to fix this ?

Answer :

Time Machine is great. But there seems to be a bug in the backup-software that causes this “No Volumes Found in backup”-error you’ve encountered. Normally, this error-message should only be displayed when a sparsebundle backup-file is corrupt (for some reason), but it turns out that it is now also displayed when a sparsebundle backup-file is incomplete…

This is probably due to a disconnection from the backup-disk during the TimeMachine-backup process (for instance because of shutting down the Mac, or switching from WiFi- to Ethernet-connection or vice-versa, during backup).

If the original files are still available on your Mac, the solution is rather simple : just go back to your Mac and use Time Machine to make a new backup. If you want extra insurance to prevent this error, either make a new Time Machine backup to a new/fresh harddrive (preferable an external USB- or FireWire-harddisk), or follow the backup-routine outlined in this post.

If the original files are no longer available on your Mac (e.g. your Mac is stolen, sold or you’ve just done a clean install on it, wiping off all of it’s data), you are in trouble…

…in that case, you could try using Disk Utility to repair the sparsebundle-file. If that works, you are in extreme luck… if that doesn’t help, you have very few options other than using the Terminal-app or a specialized expensive retrieving app like DiskWarrior (the cheaper knock-offs turn out not to work in most cases… too bad…).

I will be posting instructions on how to use the Terminal-app for this shortly (in a new post).

tip : make sure your TimeMachine-update is useable

Question :

While doing a regular check on my Mac with Disk Utility, it just informed me that I have a potential hardware failure, should save a many data as I can and reinstall.

So I was planning on doing a TimeMachine-backup and disk-reformat, followed by a clean install of OSX and copy-back from TimeMachine.

But… I recently found reports on a bug in TimeMachine, that might prevent TimeMachine from recognizing the latest backup…

Is there a way to make sure that my latest TimeMachine-backup is useable ?

 

Answer :

This bug seems to occur with unfinished TimeMachine-backups, either due to disconnection, unplugging or switching from WiFi to Ethernet or vice-versa…

As with all things in life, nothing is 100% sure or secure…

But if you want near-100% assurance that your latest TimeMachine-backup will work after a ‘clean install’, do this :

– make sure your Mac is connected to your TimeMachine-backup-disk in only one way, so if it’s an external harddisk disconnect the Ethernet-network cable and set AirPort/Wifi to OFF, to have the connection ‘only via USB’ or ‘only via FireWire’ and if your TimeMachine-backup-disk is a NAS or TimeCapsule, disconnect from AirPort/WiFi (and preferably connect the Ethernet-cable from the NAS or TimeCapsule straight into your Mac, and if possible, stop all other network-connections over Ethernet, by disconnecting all cables, and shutting down AirPort/WiFi) to have the connection ‘only via Ethernet’

– do a new “Back Up Now” in TimeMachine, and make sure it finishes completely before you do anything else (preferably, shut down all other apps before backing up also)

– then startup the Migration Assistant-app (from the Utilities folder in the Applications folder), and type your Mac’s administrator-password when asked

– in the first window, select “From a Mac, Time Machine Backup or startup disk”, and click “Continue”

– in the next window, select the disk that your TimeMachine-backups are on (if you’re on a Time Capsule, you will need to type your TimeCapsule-password when asked), and click “Continue”

– in the next window, a list of all backups (a.k.a. sparsebundles) available on the disk will be displayed ; now you will have to wait a little for each sparsebundle to display what the date is of the backup-version that can be retrieved… if that date matches today’s date, you have a perfect backup available, and you can exit the Migration Assistant-app by repeatedly clicking the “Back”-button

…but if the date is different, or the “No Volumes Found in backup”-error is displayed, your backup is useless for easy recovery ; you will have to exit the Migration Assistant-app, and start over the entire backup-routine explained above, and then check again in the Migration Assistant-app …you have to keep repeating this entire routine until you get today’s date displayed below the backup’s name

If you do not do as described above, you are in serious, enormously time-consuming trouble…  (even though this doesn’t always mean that your personal data is lost… everything might be lost, but… it could also mean you will have to repair the sparsebundle-files and/or it could also mean that you will have to copy everything back ; folder-by-folder or even file-by-file… either in the Time Machine-app or in the Finder ; and all applications will have to be manually reinstalled again…)

fixed : setting up WiFi-printing for the Samsung CLP-365W

Question :

I just bought a Samsung CLP-365W color laser printer and I am very happy with it. Setting it up for use over USB and Ethernet was easy. But since it is a wireless network-printer, I would like to use is as such. Even with the enclosed “Wireless Network Quick Guide” I have still no success in setting it up after several tries…

Do you have any idea how to set the CLP-365W up for wireless networking from my Mac ?

Answer :

Yes !

…and you are completely right : all instructions provided by Samsung are incomplete…

…and the setup-process is not always smooth and hassle-free…

So… here’s how to do it :

1- download the Wireless Setting app for OSX from the Samsung website :

http://www.samsung.com/us/support/owners/product/CLP-365W/XAC#

on that page, go to “Manuals & Downloads”, then to “Software” and click on the “ZIP”-button of the Easy Wireless Setup (Software) for Mac OS

2- install the Wireless Setting app on your Mac (it’s a drag&drop-installation)

Note : since the app’s name is just very generically “Wireless Setting” and doesn’t include any reference to Samsung, I suggest you put it in a folder labelled “Samsung” (you might already have one, if so put it there) inside the Applications folder

3- now, first make sure there is no connection from your Mac to the CLP-365W, so pull out the ethernet-cable to disconnect from your network, choose “Turn Wi-Fi Off” from the AirPort-menu in the top Menu-bar of your Desktop (the pie-shaped radiation icon) and pull out the USB-cable that might connect your CLP-365W to your Mac

4- open the Wireless Setting app

5- click “Next >” in the window that opens

6- turn the printer on, and when the printer is ready, click “Next >”

7- select “Using a USB cable”, and click “Next >”

Note : even though there is an option named “Using a direct wireless connection”, that will NOT work… too bad… neither manually connecting to the “Portthru” WiFi-network, nor pressing the “WPS” button on the CLP-365W will help…

8- connect the CLP-365W to your Mac using a USB-printer cable

9- now turn on AirPort/WiFi on your Mac, and make sure your Mac is connected to the AirPort/WiFi-network that you want the CLP-365W to connect to also (to do so go to the pie-shaped icon in the top-Menu bar of your desktop)

10- then click “Next >” and you will first see a screen indicating the search for a connection between the Mac and the CLP-365W, and after that a new screen called “Wireless Network Search”

Note : if this doesn’t work, disconnect all cables from the CLP-365W, and also take out the power cable for at least 30 seconds, then put the power cable back in and redo from step 3

11- the name of your wireless AirPort/WiFi-network will now appear in the list of SSIDs, select it and click “Next >” (if it is not listed, try clicking “Refresh”, if that doesn’t help, redo from step 3)

12- in the next screen type your AiPort/WiFi-password and click “Next >” (if you get an error, just retry)

13- in the next screen you can enable Wi-Fi Direct, which enables your iPhones, iPads and Android-devices to easily connect to your CLP-365W

the iOS app needed can be downloaded from the iTunes App Store :

https://itunes.apple.com/us/app/samsung-mobile-print/id429611283?mt=8

14- in the next screen click “Add printer” and the “Print & Scan” System Preferences panel will open ; in the “Add” window, select the one with the “Bonjour” indication (so NOT the “USB” one), adjust the “Name:” if you like and click “Add”

15- click “OK” in the pulldown window regarding additional settings, and your CLP-365W will now appear in your list of printers

Note : if you get an error that your System does not have the drivers needed installed, first do a “Repair Disk Permissions” of your OSX-partition in the “Disk Utilities”-app and make sure you have all updates of OSX installed and just try again… only if that doesn’t work you’ll need to reinstall the printer-driver

16- do not forget to close the Wireless Settings app by clicking “Finish” and disconnect your

…and that’s it !

you can now use your CLP-365W from your Mac wirelessly

Enjoy !

fixed : use unsupported scanner in OSX 10.8 Mountain Lion

UPDATE : a list of supported scanners for OSX 10.9 Mavericks can be found here

UPDATE : Mattias Ellert has now updated the TWAIN SANE drivers, so there is a new version for OSX 10.9 Mavericks (and OSX 10.8 Mountain Lion), more on this can be found here

———————————

Question :

I have a Canon CanoScan LiDE 20 that used to work perfectly in MacOSX 10.6 Snow Leopard. But now I’ve bought a new Mac which runs OSX 10.8 Mountain Lion, I can’t seem to install it, since Canon doesn’t update the drivers anymore.

What can I do ?

Answer :

In OSX 10.7 Lion and 10.8 Mountain Lion any TWAIN-supporting scanner can be used without any additional software :

– connect your scanner directly to your Mac using a USB-cable

– open the System Preferences

– then click on “Print & Scan”

– then, just below in the list of printers on the left, click on the “+”-sign

– that will bring up the “Add”-window, which enables you to add a new printer or scanner

– if your scanner is TWAIN-supporting, it will show up there, and you just need to select it and click on the “Add”-button

– then it will be listed in the previous (“Print & Scan”) System Preferences window, and if you select it (and you put a piece of paper or a photo in the scanner), a Scanning Preview window will show up, allowing you to scan your document to file or eMail or something else…

but…

…some for some printers, like the Canon CanoScan LiDE 20 and LiDE 30, the TWAIN-drivers are not included in OSX. In that case, you will need to install some generic (FREE) TWAIN-drivers :

for OSX 10.8 Mountain Lion, download and install these files (in this same order) and restart your Mac after doing so, then your scanner will also show up in the “Print & Scan” System Preferences :

libusb.pkg.tar.gz

sane-backends.pkg.tar.gz

SANE-Preference-Pane.pkg.tar.gz

TWAIN-SANE-Interface.pkg.tar.gz

for MacOSX 10.7 Lion, download and install these files (in this same order) and restart your Mac after doing so, then your scanner will also show up in the “Print & Scan” System Preferences :

libusb.pkg.tar.gz

sane-backends.pkg.tar.gz

SANE-Preference-Pane.pkg.tar.gz

TWAIN-SANE-Interface.pkg.tar.gz

– if these files do not turn into regular .pkg-files when you click on them, you need unTAR-software like this :

The Unarchiver

– if you get an error-message telling you you can’t install this software (these drivers) since the are not from Apple-appoved developers, you need to :

– open the System Preferences

– then click on “Security & Privacy”

– then make sure the “General”-tab is selected

– click the padlock in the lower left corner and provide an Administrator name & password to unlock the padlock

– then at “Allow applications downloaded from:” select “Anywhere”

– and exit the System Preferences to make this setting stick

Note #1 :

TWAIN-supporting drivers (like SANE and the ones that come with OSX) will enable you to directly scan from within various applications like Photoshop, MS Word, GraphicConverter, OmniPage and OSX’s built-in Image Capture.

Note #2 :

when using the SANE drivers, you will probably not be able to use the ‘one click’-buttons that are on the scanner itself…

Note #3 :

if your scanner lets you scan the first time, but after shut-down and restart scanning seems impossible because OSX can’t find the scanner, just plug-out the scanner’s USB-cable and plug it back in and everything should work again…

Note #4 :

if the “Scan”-button remains grayed-out, make sure that you have selected an area to scan… (put differently : if “Selection:” is set to “Off”, you will need to select an area to scan before the “Scan”-button will be ready to use…)

Note #5 :

if you get a distorted scan when scanning in landscape view (or any other rotated view), just scan normally in portrait view and rotate the scanned image afterwards (in Preview app or another image editing program, like Photoshop or Graphic Converter)

Note #6 :

if you are not able to scan as a JPEG (.jpg-flie), just scan as a TIFF (.tif-file) and convert the scanned image afterwards (in Preview app or another image editing program, like Photoshop or Graphic Converter)
