Problem with waking from sleep with 10.8.2

I have a MBP 17" late 2011. I just did upgrade from Lion to Mountain Lion 10.8.2. Immediately after the upgrade I was experiencing the exact same problem as the OP - it would take anywhere from 1.5 to 2 minutes to wake up.

I finally called Apple. They told me to:

1. Boot up holding down the CMD and R keys to get to Disk Utilities.

2. Run Repair Permissions.

3. Run Repair Disk.

4. Close out of the Disk Utilities and boot the machine.

5. Open the Finder. Hold down the Option key, choose GO from the menu and select LIBRARY.

6. From the Library drag the CACHE fold and the COOKIES folder to the trash.

7. Delete the trash.

I was sceptical but thus far it has fixed my problem.

I have the same problem with my mac pro. I have an automated wake set up to deal with the 'wake on network access' problems i got with 10.8, but even that doesn't wake my machine. Makes it pretty uselss for serving my ATV3

Same story here on my mid-2012 Mac Pro (12 core). I have to force restart. The problem began when I installed 10.8.2. I have to force restart the machine. I guess the only solution until Apple fixes this is to set Energy Saver to never sleep. PITA.

I'll add my name to the list...

Early 2009 MacPro 2x2.2GHz Quad Core Xeon with 16GB Memory and NVIDIA GT120

After update to 10.8.2 (12C54) the system no longer can be woken from sleep and needs the power button holding in to turn it hard-off and then on again.

Same problem here. 24" iMac 2.97 ghz core 2 duo, early 2009. Started with upgrade to 10.8.2. I have to force shut down and restart. I'm trying the usual disk permissions repair, but I suspect this is a deeper problem.

Has anyone attempted booting into safemode ( at startup holding down Shift till you see a progress bar)? Or did a filesystem check (not permissions) and see what happens after that?

Might be worth also trying to do an SMC reset, didn't see anyone mention that yet:

Same problem after 10.8.2 installation with retina/macbook pro. Also installed firmware update. The only way I have been able to resolve the problem is as described above--forced shutdown and then restart. I did do an SMC reset after the first instance (Saturday evening) but the problem recurred after computer was put to sleep Saturday night. One note: when I put the machine to sleep prior to the first instance of the problem, I had to choose sleep from the apple menu four times. Very smart computer did not want to go to sleep. Reminiscent of Invasion of the Body Snatchers.

Having the exact same problem as the original poster on a 2009 Mac Pro. Didn't seem to start happening until the last few days though. I think I was running 10.8.2 for a day or so before I started noticing the issue.

Early 2009 with 10.8.2 same problem.

I am able to ssh in from another competer and "sudo shutdown -h now" (-r for reboot does not work) successfully. I rather force the computer to shut itself down properly then use the power button and chance corupting anything.

Exactly same problem om my Macbook Air 11 inch Mid 2011. Upgraded to 10.8.2 a couple of days ago but problem only started yesterday. Has happened about 2 times, where just refuse to wake up from sleep. Interestingly when looking at Console Logs, on both occassions the last entry in the log is as follows:

Signal[274]: Error Domain=com.apple.coreWLAN.error Code=-3930 "Operation not permitted" UserInfo=0x400389500 {NSLocalizedDescription=Operation not permitted}

No idea what this means. Anyone know.

At moment, as Macbook Air is plugged into Monitor and in clamshell mode, is to set it to never go to sleep in the power preferences.

In General I have found 10.8.2 to be very buggy, have also had problems with Key Chain and ubd process creating 1000s of certificates and slowing everything down. Seriously considering rolling back 10.8.1.

At moment feel like I am living in Windows Vista World

I'd be curious to see, does this occur with all types of sleep occurrences?

Macs will go to sleep 1 of 3 ways:

1. Software timeout sleep

2. Clicking  > Sleep

3. Hardware mechanisms: On portables closing the lid activates a magnetic sleep switch, on desktops quickly pressing the power button sends it to sleep.

Anyone willing to post a copy of their logs from after attempting to sleep? If so:

1. Mark the time you put the system to sleep

2. After a reboot open Applications > Utilities > Console

3. Under kernel.log, provide the logs from the time your system went to sleep, till whatever the current time is.

Might be interesting to see if there's some weird issue causing the systems not to enter sleep correctly.

I've seen the same problem twice so far since upgrading to 10.8.2 on my MacBook Pro late 2008. When trying to wake, just get black screen. Nothing works, except powering off.

I don't know if the computer was actually running or not, since that laptop had all sharing turned off. SInce it happened a second time, I've turned on remote login and screen sharing.

Just saw a twist on what others have been reporting. Went to wake it just now. It is showing the login screen, but is not responding to any user input, and the password field is not highlighted. This may be the same problem, just happening slightly later in the wake up process.

However, I'm able to verify that the machine is actually running, since I just did a remote login (oddly it's not showing up for file sharing on my network).

I'm looking thru the system logs now... but not seeing anything that stands out as an obvious error related to sleep/wake. Any suggestions for what to look for?

Weirder yet... went to shut the machine down remotely via "/sbin/shutdown -h now" and it has so far not actually powered off (after 5 mins). It killed all the services, so I can no longer remotely log-in, but the computer is still powered up with the login screen displaying (although again, doesn't respond to any user input). I've never had that happen before...

I believe that the Take Control of Upgrading to Mountain Lion ebook from Tidbits discusses how to do a clean install that is the equivalent of the old archive and install. Catalog | Take Control

I wasn't anticipating having to do this so haven't yet read the clean install chapter.

I had the same issue with my early 2009 MBP. I found this option to reset the SMC, it fixed my wake-up problem. Check how to reset the SMC here: http://support.apple.com/kb/HT3964?viewlocale=en_US&locale=en_US
