Problem with waking from sleep with 10.8.2

I installed the supplemtal update and restored my Energy Saver settings to the default last night but I'm not sure if I have left my Mac long enough to get to the deep sleep that causes the problem. I have let it sleep for a couple hours and so far the problem has not surfaced but will need to test the deep sleep state before getting too excited. I was pleased to return to my Mac after a coudple of hours this morning and wake it up without a problem. fingers crossed and I will report back either way.

I too have the failure to wake from sleep with my 2008 Mac Pro. I most notice this when the machine shuts down while I have any apps up. Like so many I have tried everything to no avail. Something is wrong here with Mountain Lion. Incidentally I also have installed the supplemental update to 10.8.2. Hopefully we will hear something from Apple SOON!

Supplemental update to 10.8.2 has no positive effect on this problem.

Also unchecking "Wake for Network Access" doesn't solve it for me.

So this morning after about 8 hours of 'sleep' I had to switch my MacBook Pro off with the power button again because the screen stayed black.

When I switched it on, I ended up with the root console! The Macbook Pro had booted in single user mode for a reason unknown to me and I had to type 'exit' to perform another reboot.

This is getting weirder and weirder.

I'll stop to perform tests on this problem now and just shutdown the computer everytime I otherwise would just have closed the lid and put it into sleep mode.

This may be a dumb question but what is a "supplemental update" and how can it be found and installed? When I do a "software update", the recent updates have been for apps and they were all a few days ago. I have seen no updates via the app store in recent days that look as though they would have any relevance to the wake from sleep issue.

Yesterday I posted saying that I had applied the supplemental update and it had not solved the wake problem.

I'm revising that statement. Looks like my problem may be fixed. Following the update yesterday I found that bluetooth was not working. When I attempted to turn it on I got a message that the bluetooth module was not present and to check my hardware. Never seen that message before and wasn't sure what it meant.

I tried a shutdown and restart without solving the problem. So I did a NVRAM reset--power down, hold the command, option, p, and r keys during power up until the machine boots the second time. That fixed the bluetooth issue.

Next I turned the wake-for-network-activity option back on and let the laptop sleep. My MacBook Pro slept normally from noon yesterday until this morning. It woke normally this morning with just a click on the mouse pad. Checking the system log I saw a number of RTS alarm wakes overnight--those were the kiss of death for me before--with normally sleep operations following them.

Looks like my problem is sloved. Don't know if others will have the same success, but I hope so.

As bratman91 I didn't see the update show up in the app store. Found it by doing a google search for 10.8.2 supplemental. You can download the update from Apple support page http://support.apple.com/kb/DL1600.

I'm happy to report that the 10.8.2 Supplemental Update has fixed this problem for me. No problems at all today, deep sleep or not. Yay! 😀

I am not sure if I have the same problem.Touted here by someone responding to my post of a few days ago

I have a new MBP Retina SSD.

The MBP wakes from sleep. Ok BUT I notice something happens If I carry my MBP while it is sleeping. Especially if I turn it while carrying (or turn it to reconnect it standing in my ArcSouth stand)_

I can't get the MBP to respond. There is no light on the front , not pulsing no nothing. My initial thought has been that the MBP has shut down but I don't know. To get it respond I have pushed the power key a few times and the MBP reboots, with the dialog box that I seemed to have shut down my computer because of a problem, etc etc.

After reading some of these posts, perhaps the problem I have is NOT that the MBP shuts down but rather that it does not wake from sleep and the only way I got it to respond was to shut it down.

Don't know

Have NOT had the problem as long as my MBP is stationary. It is only motion that seems problematic, no matter if the MBP is sleeping during my hour commute to work (I.e carried in a secure backpack) or If I am carrying it from one room in my home to another.

Yesterday I followed Chet's suggestion to perform an NVRAM reset. For the first test I kept 'Wake for network access" disabled and put my MBP to sleep yesterday evening. This morning it woke and works like a charme again.

Thanks to Chet for this hint!

Tonight I'm going to reenable "Wake for network access" (althouth I've never needed this in the past) and tomorrow morning will show if the problem is fully gone.

As mentioned before I also had problems with waking up. But recently these problems have disappeared. Don't know exactly what solved this, but the problem on my MBP (early 2009) are gone.

Yahoo!

My MBP works normally again.

The NVRAM reset had a healing effect (even with "Wake for network access" enabled).

Thanks to Chet.

I believed that this might have helped some days ago, too. But it didn't.

Blubalu,

Your MBP simply did not awaken?

Did it matter if it was stationary or had been moved or carried?

I just reset my SMU

Will see if THAT makes a difference

MY issue only seems to occur if put my MBP into clamshell mode and then carry or move it.

The MBP either has shut down or does not want to awake from sleep. I cannnot determine which of those two states is happening.

Mine is a new Retina MBP so maybe there is something unique to that new model

My issues seem to only occur when I put the MBPwR into sleep mode via the Apple logo and don't close the lid first before putting it into sleep via the external monitor. If I close the lid and have the display switch to only the external monitor and then put it to sleep no issues...

I have the same problem with my MBP 13" Mid-2010. After the ML 10.8.2 update my MBP won't wake always from sleep (sometimes it actually does wake up). I tried PRAM reset, SMC reset, clean install of Mac OS X (10.8 from the app store, which installed immediately to 10.8.2 (?). The problem of not waking up occurred from then on less frequent. After installing the iLife and Java update yesterday, my Mac won't wake at any given moment after closing the MPB or after choosing the sleep option provided by the Apple menu in the top-left corner...

Any ideas?

Hi,

I had the same problem after installing a new SSD and reinstalling Mountain Lion fresh from the AppStore: after going to sleep I got problems when waking up. Either the whole system froze instantly, sometimes I could use it but within seconds one application by another started to freeze. It seems, the system could not access the disk (no entries were written into the system.log upon wakeup !)

I finally solved the issue by first starting the original 10.8.0 Installer which gave me - after reboot into the main installer - the option to "repair" (or "restore") my system.

After that everything worked perfectly. All my settings still existed.

I only got some problems which were resolved after clearing all cashes etc. (using Onyx).

As the latest iPhoto won't work with 10.8.0 (needed 10.8.2) I finally decided to give it a try using the downloaded Combo-Installer (10.8.2) from apple.com.

Now I am using 10.8.2 incl. Suppl.Update for over a week with no problems concerning wake up from sleep !

Hope, it will help you !
