OS X Lion 10.7 Sleep Issue

well it has worked for me and alot of others. try turning everything in the sharing menu off and try again to c if it fixes it. i currently only have 1 thing turn on and its bluetooth sharing and its running greet. i had the internet sharing on and it wasnt work but when i turned it off it worked.

You do not understand my problem. The problem is NOT going to sleep, what does itregularly. The problem is the wake of the mac!

Same issue here:

Close laptop lid -> Lion turns off laptop screen -> Laptop DOES NOT go to sleep.

(All sharing options disabled)

It's really annoying because I used close the lid, wake computer up again so only the external display would turn on, then open my laptop lid again WITHOUT Mac OS automatically turning on the laptop display again.

I can't keep it closed because my MBP will melt my laptop screen. So now I'm forced to either have both displays on, or keep lid closed and generate a lot of heat.

I had the same issue, resetting the SMC did the trick for me (http://support.apple.com/kb/HT3964), I also heard if that doesn't work to try resetting your PRAM (https://support.apple.com/kb/HT1379). Hope that works for you!

This worked for me. Thanks. This has really been bugging me since I installed Lion

for testing, I checked the box filesharing on and then the mac wont sleep.

i checked it off now.

but i dont understand, why apple dont fix this issue, its know a long time

I had an issue with my iMac display not sleeping. After looking at Console, I found a bunch of errors regarding an application called SoftRaid. I didn't need this app, so after uninstalling it, my the display went to sleep as desired.

As mentioned above by others, I would look at the Console for repetitive error messages. If the computer is working hard to overcome the errors with no success, then I am guessing that it may be interpreted as 'activity' and the computer won't sleep.

Apple will eventually differentiate true user input and background input to determine activity and sleep cycles in a future update.Hey, it's a point 0 release, and for the most part, it is truly excellent!

Same problem here Macbook Pro (late 2008).

There are now hundreds of posts about this. Makes you wonder about Apple testing?

Thx!! The little snitch update solved the sleep problem for me to!!

Since Lion my MacBook Pro won't always go to sleep by itself anymore either (it does when I close the lid). It used to work with Snow Leopard. Internet Sharing, Printer Sharing etc. is not akrivated. Resetting PRAM didn't solve the issue either...

Since installing Lion 10.7, my MacBook Pro also will not go to sleeo, The display goes black, but the hard drive keeps spinning. This happens both when I close the lid and when I pull down Sleep from the apple menu. I am not using an external display. Just my solo MBP with all applications closed.

KEY NOTE: This only happens when power is connected. If I detach my power cable, my MBP enters sleep mode normally.

Taking advice of this and other threads, I have:

:: reset my SMC

:: reset my PRAM

:: internet sharing, file sharing etc. is off

:: I unchecked "Restore windows when quitting and re-opening apps" (however, when I shut down or restart, my apps and windows reopen from last session; I can't defeat this).

After all this, when my MBP is plugged in, sleep mode still ain't happenin'. Sleep worked fine in Snow Leapard, etc.

MBP 2.4 GHz Intel Core 2 Duo

Resetting the SMC worked for my 11" Air - thanks

Hi,

I have the same problem over here: MacBook Pro, 27" Cinema Display and none of the things mentioned worked. Tryed the SMC reset, the PRAM reset, updated Little Snitch, I have no sharing on at all.

That really *****. And as someone already asked before: Are apple not checking their software before releaseing it to the masses?

Any new ideas what it can be? Also a question to the SMC reset: When pressing Alt+Option+Shift and the power button, do you usually get any feedback that the SMC reset worked (eg a led flashing or a tone)?

Cheers!
