Sleep and Wake problems under Lion

See my August post above -- notably, this problem had largely gone away, until the recent spate of iTunes, iOS, OSX updates. Now, I am gettin similar behavior:

When my iMac is woken from sleep by the AppleTV or the iOS Remote app, say, to play music, it will work... for a while. However, it will then stop responding -- the music will stop and the AppleTV and Remote app cannot get any info from it. The computer is awake, but you have to walk up to it and push a button. The screen lights-up and then everything is working again.

2.4GHZ Core2Duo 24in iMac

iTunes 10.5

OSX 10.7.2

I am having the same exact issue when trying to sleep my Mac Pro... what once used to be quick and efficient is now elongated and annoying. Hopefully there will be a future fix for this, as resetting the SMC and resetting PRAM had no effect. 😟

I have a 2008 Mac Pro as well. Probably, the LAST best-priced Mac Pro there was. Anyhow, that's for a different forum.

I refuse to upgrade to Lion because I don't like it, I like Spaces, and I don't feel like running into compatability issues with all my software.

Anyway, I think the sleep problem is a hardware one. My Mac Pro would not go to sleep after the set time, and would wake up arbitrarily.

To fix it I came across a piece of donationware called "Please Sleep". It monitors your Energy Saver preference pane and will sleep the Mac Pro if it does not go to sleep at the designated time (1.5 hours for me).

Good luck !!!!

I too am having this problem. I'm trying to gain remote access to my Mac Pro 1,1 while on the road. I can wake the computer over the internet but it's only partially awake and I can't get to a screen sharing session without touching the keyboard or mouse button....

Apple please fix this.

Spaces is good, but Lion's "Mission Control" and multiple desktops available with a four-fingered swipe is infinitely better, IMHO. I don't know what you use, but most of my software has made the transition without much of a problem. Just sayin'.

I have the identical problem, same as myndsurfer and the same iMac. If I set it to "Sleep" from Finder, it might sleep for a moment & then comes right back,or it might just not sleep at all. I remember having toddlers who behaved this way!

1. My 2009 iMac 21.5 has just started misbehaving as above. I have left it to sleep overnight as per usual but now when it wakes there is no mouse / keyboard etc and it has to be restarted to get functionality back. Can we have a solution please?

2. Very odd but a whole load of apps appeared in a folder I had on the desktop. Apps like terminal.app, raid utility and many more.

I didnt know these apps were in this folder, which contained some pictures, until i put the folder into trash and tried to delete the folder. Then I got warnings about deleting apps. Now I cant get that folder OUT of trash.

I copied all the apps into the apps folder.

What caused this, where did all these 'system apps' come from? Any help appreciated.

I hav the exact same problem. Mac Pro early 2008 (3,1) with Geforce 8800 GT.

When it wake from sleep over LAN the GFX fan keeps on venting on highest speed, screen stays blank.

The normal Fans are silent, but the GFX fan is hearable in the whole appartment.

I also have the issue where, after I put the system to sleep, I'll come back later to the sound of a high speed fan.

I've got a MacPro3,1 with a GeForce 8800 GT so there does seem to be a pattern.

I have similar problem. My 2010 Macbook Pro wont wake from sleep.

I upgraded like two months ago and it was smooth at that time. However, the "forever sleep" issue started to happen last week. I have tried reset PRAM, but the problem still is still there!!

Dear Tech support,

please address this issue!!

I've found that if I leave the computer plugged in while the screen is closed, opening the clamshell will confuse the sleep-wake cycle and the computer will stay asleep. When this happens, removing the mag-safe adapter and replacing it will "reset" the cycle and the computer will wake up. I am guessing that this is a flaw somewhere, but born of a necessity related to docking or remote connection. Or maybe it's just a flaw.😕

I have a mid 2010 iMac with a fresh clean install of Lion 10.7.2 (installed today) on an external HDD.

I also have an older install of Lion on the iMac's internal HDD.

In both cases sleep functionality in both operating system installs does not function correctly.

In both OSs the sleep menu and the rear switch on the iMac put the Mac to sleep, but then it cannot be awoken from the Apple BT trackpad or keyboard, and worse still, the button on the rear of the iMac causes a cold restart.

This was never a problem with 10.6.

It's hard to believe that people are not screaming from the hilltops to get this fixed. Does it only affect a few Mac users?

- If the screens are already into sleep state (activated via ctrl-shift-eject), you cannot put the Mac itself into sleep by pushing the power button.

Instead, the screens wake up and nothing happens, the mac won't go into sleep. However, the Mac goes into sleep from normal screen activity.

I have this problem.

Slightly different for me with Lion 10.7.2

When I come back to my sleeping iMac and move the mouse, the screen appears exactly as it was when I left it, but as I start to move the mouse about, I'm kind of rubbing out (like a pencil eraser) the screen with 1cm squares and underneath is the normal grey login screen. I have to rub out enough so that I can see my username, then click on it to get back in.

It's not right.

I have an early 2008 MBPro. I installed Lion around November 20th and initially there were no problems. That has changed. In the last 2 weeks it has not wanted to wake from sleep. A few days ago when taking it out of my carry bag it was extremely hot and would NOT wake from sleep. I did a hard shut down, took the battery out and then back in and it booted fine. Today, when trying to wake it up it turns on, but seems to boot into sleep mode. None of the keys are responsive. I tried booting into the Snow Leopard disk for disk utitlity, but it absolutely won't. Any suggestions? PLEASE???
