Is anyone else having a problem with a complete system freeze after Mac wakes from sleep mode? Post OS X Yosemite install.

Exactly the same, Mac mini (late2012)

I have the exact same problem every time coming out of system sleep. I can move the mouse but I can't click on anything nor type in my password.

Mac Mini (late2012).

I upgraded to Yosemite from Mavericks yesterday and have the same problem. Talked with service rep and they walked me through several steps to try and find the problem. No solutions found. They said the next step would be to try and download Yosemite again, which I did, and reinstalled , but have the same problems. Hope they come up with a fix for this. Everything else seems to be working properly.

Late 12 Mac Mini and exactly like above unresponsive screen, mouse moves ok but can´t do anything but hard boot...

Dock doesn´t show either...

Happens to me all the time, screen goes black but I see my mouse. I usually close my laptop and reopen it repeatedly and click and spam on my keyboard, sometimes I have to press the power button a few times, but eventually it comes on.

Yes! same thing. Late mac mini (2012), mouse moves and can't click anything. Also, rebooting sometimes causes all static screen. It didn't do it this morning, however, and I had pushed the power button to wake it up instead of the spacebar. Next time I will use the spacebar and see if that does it.

This happens to me too 😟 and it is really frustrating..

Mac mini (Late 2012) with Yosemite 10.10

Hey all, so as @caponey said, I tried waking the mac from the mac power button instead of pressing some keyboard buttons or moving the mouse and that seem to work for me too..

Same here. Ever since I installed the public beta for Yosemite, experiencing freezing after my IMAC (2009) wakes up from sleep. I did reinstall the new release on Thursday, but the problem persists. I have to restart for it to go back to normal. Very frustrating Apple! Please fix.

Same here. And I, too, have a Late 2012 Mac mini. For a while, in System Preferences, I turned off putting hard drive to sleep and set the computer to "never" sleep. That worked for a about 12 hours. Back to total freeze.

dothan08...please keep this thread posted with your latest news. I'm ineligible for Apple support because I'm way past my 1-year warranty. So you're our source of news and tips from Apple support.

I recently installed Sophos anti-virus to verify my hard drive was clean after I landed on a page that wanted to take over Safari (I Force Quit Safari because the page wouldn't let me navigate away). I may delete that app and see if things improve. I note that most people on this thread also have a Late 2012 Mac mini.

Also, I've changed the Energy Save system pref in several ways but I still get the freeze on waking from sleep. However, I unplugged my external USB Western Digital drive and so far so good: I'm able to log in after the mini has been asleep.

So thanks for your reporting on Apple support's response. Please keep us up-to-date.

Also the exact same problem. I can use my mouse and my trackpad to move the cursor around the screen. However, I can't enter my password with my keyboard. It's worth noting that even the caps lock light won't turn on.

Mac mini (late2012)

My was like After I updated my computer into the newest OS version, it has gone numb and so freaking slow, it gones rain bowing each and everytime I'm clicking on something and even when I'm typing this it just gone almost frozen.

I have the exact same issue for the first time after installing Yosemite. On resume from sleep, I can see the desktop, and can move the cursor with the mouse, but clicking on icons, etc. does nothing, and the keyboard does nothing. A cold boot works fine. This is a Mac Mini bought in the Summer of 2014. I run no unusual software. I have eliminated all log in items in Preferences/Accounts, reset the NPRAM, have no peripherals (other than standard Apple mini mouse and wireless keyboard), and have shutdown and unplugged to reset. It makes no difference whether a password is required or not - once it goes to sleep, this is the result, and only a forced shut-down by holding the power button and a cold boot give me control back. This problem does not appear if it merely goes into screensaver mode - which I invoke with a hot corner.
