My 2011 iMac won't wake from sleep mode

Reset the SMC and PRAM each 2-3 times back to back using the instructions in Intel iMac SMC and PRAM resets. Then retest.

If the problem persists please reply with an EtreCheck report of your system and we can look for obvious issues.

As a general rule of thumb, NEVER upgrade any OS unless it is working perfectly to begin with. Upgrading a OS that isn't working okay makes troubleshooting problems ever more difficult to detect.

another long-term ongoing issue I've had

What is that, and is it resolved?

Please read this whole message before doing anything.

This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.

The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.

Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem.

Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Ask for further instructions.

Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.

The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.

Test while in safe mode. Same problem?

After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

Thanks for the advice. I will try out the SMC and PRAM checks again as you suggest and see if it resolves the problem and will let you know. I have EtreCheck installed so I can do a report. I have checked Console and it is telling me that there is a an error showing as:

21/09/2015 08:29:05.750 powerd[50]: com.apple.message.domain: com.apple.sleep.failure

com.apple.message.signature: Platform Failure

com.apple.message.summarize: YES

SenderMachUUID: D88AA2E5-ABBC-3B2B-B53C-17A92A95F274

I don't know if that is relevant?

For your info, I did the upgrade when Yosemite was first released and I was using Mavericks at the time, which was working perfectly.

Thanks again

Donna

Please post the complete Etrecheck report, posting just an error report doesn't tell too much except to confirm what we already know.

Safe booting causes some caches maintained by the system to be rebuilt, and sometimes that's all it takes to solve a strange problem. I tend to doubt that it has been solved, though.

Hi

Just thought I'd let you know that since I carried out your resets - so far - I haven't had the problem with the iMac refusing to wake. It's looking promising that it may have fixed the issue. I'll let you know if it does happen again.

Many thanks for your help.

Donna

Your welcome.

Hi there

Really thought this problem had disappeared but it's happened twice again yesterday, the iMac wouldn't wake from sleep and I had to force a shutdown and reboot on both occasions.

So this morning I ran the Etre Check and here is the report:

Would really appreciate it if you can offer any further advice or suggestions as to what might be the problem.

Many thanks in advance.

Unfortunately you have made a bit of a mess on your computer. You have installed antivirus software which is 100% unnecessary and possibly the cause of the problem. OS X does not need any antivirus, cleaning or other third party tools to maintain itself. There are no virues for OS X, however there is a small amount of malware which is very easily avoided by:

• Do not use a torrent to download anything
• Keep OS X up-to-date
• If you get an ad, pop-up, e-mail or phone call advising your computer has been compromised, these are all SCAMS!

Also you have installed worthless WD software on your computer, uninstall it immediately.

Once you have uninstalled the antivirus & WD software run another EtreCheck report and post it and we will look for any other issues and confirm the apps are now gone.

Good luck.

I don't see any active A-V software in the report.

The Western Digital drivers have not been installed, they are simply present in a couple of utility apps that aren't running.

trusteer.rapport is known to cause issue for some users, but I've never heard that it prevented wake from sleep, and some financial institutions require it.
