Issue: How to Fix Freezing Screen Saver On Mac OS?

When I don’t use my Mac for 15min, the screensaver turns on automatically. Probably such settings are set in most of Macs. The problem is that very often Mac’s screensaver freezes. In other words, when I get back to my Mac and try to wake it up, I move the mouse (which moves), but the screensaver won’t go away. Or sometimes it happens that the screensaver turns off, but right after that the mouse freezes and I can’t do anything except to turn off Mac manually. Do you have an idea why this may happen? I’m using Mac OS X. Any help would be appreciated!

Solved Answer

Freezing screensaver on Mac OS running devices is a common issue that happens for most of the users from time to time. Unfortunately, but it’s not clear why this issue happens, but don’t fall for panic because Mac experts have already found out several fixes for screensaver error.

What happens when screensaver freezes occurs? When the user doesn’t perform any moves on Mac for 10, 15 or 30 minutes (depends on the settings adjusted), the Mac’s system goes to sleep mode and the screensaver is turned on. When the user gets back to the Mac and attempts to use it, it appears that his/her keyboard’s hits and mouse’s moves are in vain as the screensaver won’t go away. In some rare cases, the screensaver turns off when clicking the mouse, but right after that the mouse freezes and no moves can be performed with the Mac. Beware that mouse clicks and keyboard hits are registered, so don’t start hit and click those devices nervously because you may cause further problems.

As soon as the user finds a stuck screen saver, usually he or she hold a front button and force-shutdown Mac. This method helps single time, but, unfortunately, don’t fix screen saver error. Consequently, the screen saver freezes again and such instances may start happening more and more often unless some real fixes are applied. Thus, to fix stuck screen saver, try the following fixes.

Reset the NVRAM (non-volatile random-access memory)

Although that sounds serious, don’t worry. This fix is not that difficult as you may find it at first. NVRAM is a storage that is responsible for keeping data like screen resolution, speaker volume, mouse, and track pad. For some reason, NVRAM may get damaged or corrupted causing the screen saver to freeze and similar issues. Therefore, to fix stuck screen saver issue, try resetting NVRAM first.

  1. Shut down Mac.
  2. Press the power button and hit Cmd + Opt + P +R command with your keyboard.
  3. Keep these keys until you hear a startup sound for the second time and then let the system boot up normally.

Use your Mac as usually and if you won’t encounter stuck screen saver, then it means that resetting NVRAM has helped. If, however, this problem reoccurred, then try the next fix.

Force Mac to sleep manually and wake it back up

If you force-shutdown your Mac, you may find the last document or task you were working on damaged. Nobody wants this to happen, so to unfreeze screen saver, you should force Mac to sleep and then wake it up manually.

If your Mac’s screensaver freezes again, quickly tap power button (for a second, no longer). This will force Mac’s system to sleep, what means that pressing the power button will wake it up. Unfortunately, but that’s just a temporary fix, so you can use it and wait for the permanent fixes that may be found every minute.
