Energy saver display sleep function not working after upgrade to Mavericks. Any idea why?

I take back everything I've written in earlier posts, this morning I have only used Safari and my own files from Finder and now my display sleep and computer sleep not working, I have tried resetting SMC etc, no joy

Totally mystified, I'm just going to have to get used to clicking on sleep!

I think you're on track here. I've always had my screensaver activate first, then display sleep kick in eventually if I haven't used the computer for some time, but what's been happening since switching to Mavericks is the screensaver just stops at the display sleep time and the displays go back to full on. I've turned off screensaver entirely and now the display goes to sleep after the scheduled time.

Obviously this isn't correct behavior.

Hi Dave,

I've not (yet) experienced the effect you get, if my Mac is not working properly it will usually but not always just stay on screensaver.

For your info my system is iMac desktop, Apple TV, Time Capsule and iPad mini on which I use Remote App to play music through Apple TV and then speakers, just recently an electrician came to the house to check on replacing kitchen lights while I was out, apparently he had power on and off 6 or 8 times in about 10 minutes, after that Apple TV was very poorly, rebooted it still didn't work. I decided to do a full reboot of everything in the order that one of the AppleCare guys told me was best, shutdown and unplug my iMac unplug router and Time Capsule unplug Apple TV shutdown iPad

Reboot in this order, plug in router (wait five minutes) plug in Time Capsule (wait for solid green light) plug in iMac (wait five seconds) power on iMac let it start up fully then plug in Apple TV and let that reboot, finally reconnect iPad.

Screensaver, display sleep and computer sleep all worked perfectly for about two weeks then went to pot again, if screensaver worked it would stay on screensaver and not shutdown, if screensaver didn't work then display sleep and computer sleep would work.

If I reboot and reset SMC it all works again for a while then goes weird on me again, I've given up trying to work it out, there seem to be too many variables.

Yep, it was Chrome. Thanks for the fix!

I had the same problem with Mac OS Sierra.

In the Energy Saver preferences I have disabled the "Wake for network access".

That solved the problem. Now the sleep function works again.

Well it seems the problem was not related to the "Wake for network access" option.

I am sorry for the misunderstanding post.
