fixed : quick way to make hidden files visible on macOS

Question :

I sometimes need to view the invisible files on my Mac. I know I can do this using the Terminal.app, but isn’t there an easier way to do this ?

 

Answer :

To turn on the ‘Hidden File Viewer’ (or ‘Invisible File Viewer’) mode in MacOSX, you could use the command line in Terminal.app or you could use little apps named something like ‘Hidden File Viewer’ or similar.

In macOS 10.12 Sierra and newer, there is a far simpler way to do this :

  • press the [SHIFT] + [CMD] + [.] key-combo on your keyboard

Using this key-combo, you can switch the visibility of invisible files ON or OFF.

That’s it !

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

Question :

I have a  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 😉

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 : compress video for WhatsApp (or eMail)

Question :

I would like to send a small piece of a video I just shot at a birthday party to a group of friends on WhatsApp, but it’s too big to upload.

How can I compress it for easy viewing on Whatsapp ?

 

Answer :

If you have shot the video on your iPhone you can send it right away, and iOS will do the compression for you.

However, if you already have the video on your Mac and you want to compress it before you send it using WhatsApp Desktop (for macOS), do this :

  • make sure you trim down the length of the video to a clip that only includes the most relevant part of the video
    • you can do this in QuickTime Player (included in macOS for FREE)
  • use Smart Converter (FREE from Mac AppStore) and choose ‘for iPhone or iPod’, then click ‘Convert’ to convert
    • this will convert to an .mp4 video with 1280×720 resolution at 30 frames per second and AAC sound (file size ca. 10MB per 10 seconds)
  • use Handbrake (FREE from handbrake.fr) and choose ‘Presets’ > ‘Gmail Large 3 minutes 720p30’, then click ‘Start’ to convert
    • this will convert to an .mp4 video with 1280×720 resolution at 30 frames per second and AAC sound (file size ca. 2MB per 10 seconds)

Note : even though the frame rate and screen size are the same, the ‘Gmail’-ready file will be much smaller than the ‘iPhone’-ready file, even though (or rather ‘because’) this comes with the downside that quick-moving objects will blur in the ‘Gmail’-ready video (compared to the ‘iPhone’-ready video that hardly has any blur and is similar in size and quality to the ‘Fast 720p30’ preset in Handbrake) 

That’s it !

fixed : Jaksta records .mp4 movies that QuickTime can’t play

Question :

I have been using Jacksta Media Recorder for a long time now, and it has always worked marvelously for me when I need to download a video. Jaksta can download nearly any online video that I can watch in Safari.

But recently, Jaksta does download the exact videos I want, but the downloads turn out to be .mp4 files that QuickTime hangs on when trying to play them…

What can I do ?

 

Answer :

The exact reason for this is unknown, but it might have something to do with the fact that not all browsers play HTML5-videos using the same technology.

It turns out that your solution is to use the Google Chrome (or Firefox) web browser – instead of Safari – with Jaksta running in the background. That way, when you play the online video in Chrome (or Firefox), the file that Jaksta downloads will be a .mp4 video that QuickTime can play without any problems.

That’s it !

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 😉

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 😉

enjoy !
