Sleep wake failure

Could you please define 'freezes'? It is the black screen moving cursor issue?

same thing for me

ever since installing Yosemite, when I bring the Mac mini back up from its sleep state, the only thing I can do is see the mouse cursor move around the screen but can't click on anything, can't even bring up the system menu...nothing (this is what freeze looks like on my computer)

the only thing I can do is do a hard re-boot

hope this gets solved soon (reminder to self: don't install software updates until a year after they've come out )

I also have a Mac Mini (2012) which now after waking from sleep allows no mouse or keyboard input. The UI and mouse pointer are all displayed correctly but no response from mouse clicks or keyboard commands.

I had the similar problem on my rMBP. Called at Apple. Apparently i had to move some folder i think System Preferences to desktop and do a pram reset. After that everything workes lile a charm. I think that folder is somewhere in library/preferences/... I ll try looking after it asap i get home.

thanks..looking forward to you posting the fix...

Press command+shift+c - > Macintosh HD - > Library - > Preferences -> Drag SystemConfiguration on desktop, it's going to make a copy of it (May ask for password, then delete it from the Preferences (which is the initial folder). Shut down, then do a PRAM Reset. If you don't know how to do that :

After you shut down the computer, locate the option, command, P and R from your keyboard. Press the power button to turn it on and quickly press all four buttons before hearing the first 'power up sound'. Keep them pressend until you hear a second 'power up sound'.

That's how i solved mine (i have to SPECIFY that i solved that on MAVERICKS). Hope it works with Yosemite.

Let me know if you fix it.

worked great Thank you !

Unfortunately no luck here on my Mini late 2012😢. Had also tried a SMC reset, nothing changed.

Oh, wait, it's now working again!🙂 Had found in Console log a little little MIDI app from the last century which didn't had any startup entry and happily came with it's own deinstall routine. Running, reboot, problem gone🙂🙂🙂

(PS: Wow, how could such a little, old proggie do such harm to Yosemite? Have found out that after deleting the dwarf several other issues are also gone, like "Handsoff" probs or the missing "Do not disturb" button in Notification Center. What a little *******...😉)

What you actually did to see those apps / the cause of the problem? Guide us. The mavericks copy that got updated into Yosemite wasn't old (like 1 month) but it guess it won't hurt checking for hogging-ram-cpu-os apps.

@nick i am glad it worked for you 🙂

@Darkkz:First i had to scan the Console logs for something around the exactly time stamp where sleep wake get into business again. That wasn't tough, because the folks in this issue see a simple screenshot instead of a live monitor view and the screenshot has a time stamp in the right above corner by system clock, i.e. 23:09. "WindowServer" make this screenshots, it prints a something "screensaver" message in the logs. Then i looked at all app-related messages around this time stamp and found my little a..hole, recognizing that this app hasn't had an entry in all of my Maverick/Yosemite app places at all.

spoke too soon...still not working, plus my Telus mail account doesn't work again the only way to make it work is to delete it and then re-create it

this is starting to feel like windows....

Ok, when i spoke to that Genius, the next step would've been creating a temporary account and using it for a couple of hours, to see if the problem persists through that account. If not, then it's an account related problem, tho' you have to migrate your infos into a new one in order to get rid of it. I was lucky, because on Mavericks i fixed mine that way (SMC reset + deleting the Preferences Folder), but not smart enough because i did a 0 day update. And now too lazy to go back to Mavericks xD

My 2012 Mac mini have the same proublem. And I reset the PMU (Mac mini (Late 2005 and earlier): How to reset the PMU)，the problem is solved. U can try it.🙂

Seeing the same issue here with a Mac Mini 2012 - wake from sleep, mouse cursor moves but background is a static image, no UI interaction possible.

This happens even at the login screen after a restart, i.e. no user has logged in.

Deleted SystemConfiguration folder, reset SMC and zapped PRAM - problems still persists.

I am pretty sure this is something to do with wireless networking/wake from sleep as if I delete the Wifi network interface completely from System Preferences the freeze does not happen when I wake up the Mac Mini.

If I add it back, even leaving it unconfigured and not connected to any network the Mac Mini will always lock up as described above.

I cannot see anything obvious in the log file that looks like an error on wake.

For now I am turning sleep off for the computer.
