A frozen or black screen after sleep on Mac OS X 10.10.2 (beta 1, beta 2, beta 3) is often caused by a incompatible third-party display driver and is easily fixed by removing that display driver or delete completely the third-party app, e.g. via using CleanMyMac 2 for completely uninstalling the app. In my case, the culprit was AirParrot 2, an app for screen mirroring to an Apple TV or Chromecast and for desktop extension to a Mac or Windows PC.
There are multiple sources for a frozen or black screen. In the case of an incompatible display driver, the indications are as follows:
- The display remains black after waking from both full sleep and ‘energy-saver” display shut-off. Meaning you got a black screen when awaking the Mac or try to activate the display. To be clear: the display is not OFF. Just black. You can change the backlight up and down, thus displaying a very bright or very dim black screen.
- The keyboard backlight is fully functional as well.
- The mouse pointer isn’t visible and no trackpad gestures work.
- The only way to actually get the display back is a hard reset.
- Other tweaks like resetting the System Management Controller (SMC) or Parameter Random-Access Memory (PRAM) did not work.
- The issue is present regardless of whether you intentionally put the machine to sleep or allow it to turn off on it’s own.
In my case, the AirParrot 2 display driver caused the frozen and black screen issues on my MacBook Pro 13′ retina (End 2013), similar to the reported problems in the Apple Support Communities. AirSquirrels, the makers of AirParrot and AirParrot 2, are aware of that problem and are working on a fix. AirParrot (1) and AirParrot for Chrome OS are working on my MacBook Pro 13” Retina (End 2013) without any issues.
In the meantime, you can solve the issue following this work-around:
- Start AirParrot 2 on your Mac running on Mac OS X 10.10.2 (beta).
- Go to the menu bar, click on the AirParrot icon, then on the gear-wheel at the right buttom and select ‘Preferences‘.
- Click on ‘Uninstall Display Driver‘, quit ‘OK‘ when the question ‘Are you sure you want to uninstall AirParrot 2 Display Driver?’ is prompted.
- At last, you must reboot your Mac. After that, you should not have any frozen or black screen issues anymore (This works for me 🙂 ).
- If you still have some, uninstall Air Parrot 2 completely from your Mac. The best option is to use apps like CleanMyMac 2 to get AirParrot completely removed from your system.
Update (Dec 27, 2014): The AirParrot 1 and Air Parrot issue is fixed.
- AirParrot for Mac 1.6 is Available (includes fix for AirParrot 1 on Mac OS X 10.10.2 Yosemite)
- AirParrot 2 for Mac and Windows Version 2.1 is Available (includes fix for AirParrot 2 on Mac OS X 10.10.2 Yosemite)
If you did not install AirParrot 2 on your Mac, but you face the frozen or black screen issue, then look for apps you installed within the last couples of days, update them and, if this does not help, remove one by one to find the culprit. Best candidates are Adobe apps, e.g. Adobe Flash Player, or outdated Java versions.
Finally, I could fix my frozen or black screen issues by removing AirParrot’s display driver without the need to completely uninstall AirParrot 2.
Stay tuned! 😉
