Wake from sleep in 10.8.5

Try Combo Update.

Mac computers: Progress bar appears after waking from sleep

I have the same problem on my late 2012 21.5" iMac. It was really noticeable straight away.

I have installed the combo update as suggested, reset NVRAM and repaired permissions, but the problem persists. It was definitely 10.8.5 that caused this and I'd love to find a solution.

Sleep – Slow Wakeup/Requires Reset

All nice ideas - but when it worked fine under 10.8.4 and now fails under 10.8.5, I blame the OS ratehr than one of my own settings.

I don't have this issue, which is strange because usually when Apple software sneezes, my computer gets the flu. I'm using a MacBook Pro though so maybe the issue only affects desktops - I've seen a few posts on forums regarding other iMacs and Mac minis. My guess is, that this is a glitch in the software causing a power issue. You can try resetting your SMC (System Management Controller), which is usually a quick fix to power issues - but my guess is that Apple will adress this issue shortly. Resetting your PRAM may also help, if the issue is non-power related.

I'd already tried resetting PRAM, which didn't help, but didn't think of SMC, so thanks! I will see how it goes...

I've tried combo update but that hasn't helped.

2012 27" iMac. Whenever I wake from sleep it take 10-15seconds for the display to turn on. Then no keystrokes are acknowledged in the password box, then the beach ball comes up and finally all the keystrokes are inputted at once and the log in happens aburpt.

never this bad before 10.8.5

The SMC reset didn't help. But I have something further to add. I have the wired keyboard, but Magic Mouse and Trackpad (wireless). It's these wireless peripherals that are taking about 10 seconds to re-connect; the keyboard is functional straight away and I can logon with no delay.

That said the iMac is still taking longer to wake in the first instance too.

Yes I've found that I have a wake-up issue with my MBA when my magic mouse is connected - but that was way before OS X 10.8.5 .

Hope your issue is resolved, too bad the SMC reset didnt help. Hopefully it will be solved soon!

Saw on some other threads issues with external drives and such. I turned my external BD drive off, and it seems to wake from sleep better now. Turned it back on and wake was slower, but not as bad as before (but I may not have waited for the BD drive to completely auto off?). Will see what happens in the morning. (if this is a fix, it still shouldn't be happening..)

Others with the issue - any external drives of any kind??

(I'm on an imac, btw, not a laptop)

Yes I do have an external drive (USB 3.0). I did wonder if this was causing the issue. I will try disconnecting it and see if that helps.

Confirmed. Turned the BD drive back on, mac went to sleep for a few hours (overnight), and in the morning the 'wake up' issue returned. So we may have a diagnosis. Anyone else have luck with that?

Interesting that while wake-up took longer, the BS drive activity light never came on...

i don't have any externals connected to my imac and i still experience slow wake from sleep mode....

i tried unpairing and repairing all my bluetooth devices and check/uncheck "allow bluetooth devices to wake this computer" and at first it seems like there was an improvement but alas it didn't work as it takes just as long to wake from sleep and the keyboard is unresponsive for the first 10 seconds after display turns on.

I wish i could go back to 10.8.4
