When iMac awakes from sleep, the screensaver has frozen

I recently added a new user account to my iMac (running OS X Lion v. 10.7.3). When no one is signed in, I have it set so that a screen saver comes on over the login screen after 5 minutes and the computer display goes to sleep after 15minutes. Whenever I awake the computer, the screensaver has been frozen (presumably where it was when the display went to sleep) and I have to aimlessly move the mouse around, "uncovering" the login screen beneath as I go until I can find the user I want to log in as. The screen saver doesn't go away entirely until I've logged in. Is there any way around this without setting the computer to go asleep and not just the display? I often have programs running in the background that need to be.... I have tried changing the screen saver several times and it always occurs. Thanks!

I have that problem on my Mac mini. The mini becomes so dysfunctional as to be unusable after it's been idle for a while. Even DVDs won't mount (or eject) without a reboot. <edited by host>. It's disgraceful. Apple should be ashamed of this Lion release, it clearly isn't ready.
I don't think there is anything you can do short of re-installing Snow Leopard until Apple releases enough bug-fix updates to fix the Lion mess. In the mean time, just hope that Lion doesn't eat your Mac, especially if it's a mini.

Mouse locks when iMac awakes from Sleep or FrontRow

Have just gone back to Mac after four years of gloom on the PC. Bit nervous about being an early adopter but couldn't resist.
So, brand new two-day-old iMac, and it appears to have a problem: When the iMac goes to sleep, or if it is in Frontrow mode, and it awakes or is switched back to the Finder respectively the mouse is completely dead. At first I thought that the system was hanging (having read reports of similar problems on here) but I have discovered that simply by unplugging the mouse and replugging it in, the mouse comes back to life.
Anyone have any ideas? Everything else appears to work fine - so far.

Bill, good question,
there should be some default shortcuts:
Toggle keyboard access on/off --------------------
control F1
focus to the menubar --------------------
control F2
focus to the active window --------------------
control F4
focus to the window toolbar --------------------
control F5
Thanks! I didn't know about holding "control" with F2.
Now I know what to do if the mouse locks again:
control F2, then press arrow down a few times to get to "Restart", then press return.

When Lion awakes from Sleep the whole system is sluggish? Must restart computer to get it back up to speed.

Upgraded to Lion and when the computer wakes from sleep it is incredibly sluggish. Takes 1-2 minutes to switch between applications, typing is very slow, etc. Only thing that cures it is restarting the Mac. Is this something others have experienced and can it be fixed?

Folder always opens when imac wakes from sleep

Don't think its a huge problem but when new imac wakes from sleep the same folder always pops up on screen(shaded in black). It always has to be closed before I can proceed with anything.Any suggestions would be appreciated. Also the folders name is always highlighted red. Thanks

When my IMac awakes from sleep mode, the password login screen freezes and no cursor appears.

Hello! When my IMac awakens from sleep mode, my log in screen is frozen (I can't type anything) and there is no cursor.
I can turn the computer off and on again and then I have an active log in screen, but if I walk away from the computer and it goes into sleep mode and i have the same problem trying to bring it back from sleep mode.
Thoughts?

Hey Kristogirl,
I understand that when waking from sleep mode, your iMac freezes. Try executing these two troubleshooting steps:
Intel-based Macs: Resetting the System Management Controller (SMC)
http://support.apple.com/kb/HT3964
OS X Mountain Lion: Reset your computer’s PRAM
http://support.apple.com/kb/PH11243
If neither of those help the issue, I would follow the steps in the next article, specifically the "If the issue occurs in various applications, or in Mac OS X" section:

Sharing error when iMac awakes from overnight sleep

Every few days I get this error message when my iMac wakes from sleep. The error is "The name of your computer (my computer name) is already in use on this network. The name has been changed to (new name). I must then go to Sharing and change name back to the correct name. My local Apple store advised me to go to Recovery and download new version of Lion. I did same, but this action did not stop the problem.

Apparently corrected the problem. I was connected to network via ethernet cable as well as wireless. I shut off my wireless. Problem has stopped.

OS 10.8.2 on an imac. Whenever I wake from sleep, the wifi has disconnected and I have to use the Netowrk Diagnostics in the Network settings to log back in to my router. Every time. is there any kind of fix for this?

I am running OS 10.8.2 and everytime I wake my computer from sleep, the wifi is disconnected and I have to use the Network Diagnostics assistant to reconnect to my router. Is there any way to get it to not disconnect everytime? I have resorted to just leaving Network Diagnostics open and just rejoining the network every single time I wake the computer. Any help here?

Cannot login after awaking from sleep (login screensaver sleep problem)

After awaking from sleep or returning from the screensaver, the "loginwindow" of system.login.screensaver (visible after checking "details") does not recoginze the correct password. It is not possible to login this way anymore.
Very annoying!
Fortunately, I found a workaround using the functionality to switch users. The standard OS X welcome screen recognizes my password.
Anyone experiencing the same or with a way to correct the initial problem?
PS: the user account in question is a "network user"; it works as expected for a local user

More info:
It seems to be the screen going to sleep, not the computer. When I come back and touch the mouse or the keyboard, as the screen lights up, there is a flash of the web pages I left up, then they vanish.
Yikes!!!

AIR event when computer awakes from sleep mode?

Hi,
I have an AIR app that displays a new set of photos every 12 hours. Some users are complaining that the photos are not refreshed after 12 hours if the computer had been in sleep mode over night.
At first I thought possibly the Timer was stopping when in sleep mode so I instead modified the Timer to execute every minute and just check to see if the last refresh was at least then 12 hours ago. This still did not solve the issue.
Is there an event dispatched I can listen for to detch when the computer awakes from sleep mode? Or if any one has any other suggestions.
Thanks,
Ryan

Networking issues following upgrade to 10.5.8 when iMac wakes from sleep

Hello,
I recently upgraded to 10.5.8 and I'm now experiencing issues with network connectivity following the iMac waking from sleep. I have to stop Airport and then start it again to resolve the issue.
Can you provide any resolutions to this or advice?
Many Thanks,
Sam

Reinstall the Mac OS X 10.5.8 Combo Update because the Combo seems to help a lot of people when a Delta upgrade doesn't take right.

WIFI slow to reconnect when phone awakes from sleep mode

Today, I updated my LG G3 to Android Lollipop. I have WIFI set to turn off when in sleep mode (unless device plugged in). Now when the phone comes out of sleep mode, it takes up to a minute before the WIFI connection is reestablished. With the previous version of the OS, WIFI reconnected immediately after awakening from sleep mode.
Has this problem been reported to Google? I have not found a way to report bugs directly to Google as a user.
Thanks,
Tim

Joel, thanks for your reply. I've followed your instructions, and the problem persists. I assume by reset, you mean reset to factory settings. No. It has been rebooted, and powered off/on several times since the OS update. I have no idea whether there are any apps that use WIFI only. How would I know what each app may require?
Since this happened immediately after the OS update, the logical conclusion is that the update caused this behavior. In my 45 years as a software engineer, I can say this is the most likely cause.
Now, here are two more observations. When I first power the LG G3 up, the WIFI connection is made immediately; before I even unlock the device. So, we know the OS is quick to establish connections upon power up. It is only when coming out of sleep mode that the WIFI connection is slow to be reestablished, taking about a minute as opposed to immediately with the prior OS version.
The second observation is that with my wife's Samsung Note 4, which was updated to lollipop several weeks ago, I do not see this delayed WIFI connection after being awakened from sleep mode. With the Note 4, the connection is reestablished immediately with lollipop as with the prior OS version.
Considering the difference in behavior between the Note 4 and the G3, I would conclude that LG made a firmware change for lollipop which is causing the delay, or LG didn't make a necessary firmware change for lollipop which is causing the delay. At this point, I would say this is an LG G3 problem. It should be easily reproduced. Under the advanced WIFI settings, the setting "Keep WI-FI on when screen is off" should be set to either "Only when plugged in" or "No".
Thanks again for your help.

Open browsers quit when computer awakes from sleep mode

This happens onlyon my Powerbook G4 15" 1.33GHZ, and not on my iBook 700MHz. When the PB awakes from sleep mode, any open browser quits. Following is, as an example, the debug output in Terminal of Firefox quitting (I have already sent those reports both to Apple and to the authors of the browser).

External hard drive won't power back up when iMac wakes from sleep

I have the external hard drive connected via USB. I always put my iMac to sleep before going to bed and I wake it up when I come home from work. Except that when I do, the external hard drive doesn't power up. It still shows in Finder, but clicking on it's folders just opens them up as if they were empty. There's no access noise and the drive can't be ejected.I have to switch it's power off and turn it back on for it to spin back up.
At first I thought it was because I had Energy Saver set to power down the drives whenever possible, which works just fine when it's on, the drive powers on and off as needed just as long as the iMac doesn't go to sleep. I turned it off just to make sure and it made no difference. As soon as the iMac goes to sleep and the drives powers down, it will not come back on without a power cycle once the iMac wakes.
I've used this drive in an old Macbook for years without having this problem. The only difference is that the Macbook was on 10.6.8. I was thinking about buying a 4 bay USB enclosure and filling it up with hard drives, but I'm not about to do that if every time I put the iMac to sleep, the whole thing will not power back on without a power cycle.
Any help would be much appreciated.

Not sure if you managed to get this issue resolved yet Marcus, but I too have a similar problem:
Currently I'm upgrading from Leopard to Lion (via Snow Leopard) on both an iMac and MacBook Pro (both Intel), but before I proceed with the OSX upgrade I wanted to back everything up. Thus far I have partitioned an external firewire drive (G Drive - one that is bootable), and cloned each machine using Carbon Copy Cloner to it's own partition (both GUID). There is plenty of space left over on each partition.
The issue - I can boot the OS X from the external drive on the MacBook Pro but not on the iMac.
When I restart and hold down Option on the iMac the only drive that appears is the HDD, not the other two selectable drives that are visible if I boot up on the MacBook Pro. On the iMac in System Prefs > Startup Disc I can see all 3 drives but when I select it and restart, the machine freezes on the grey loading screen and goes no further.
Not that it should make a difference, but there is a 3rd partition on the external drive that is currently empty (for extra storage).
Any help is greatly appreciated - I can't find any relevant answers elsewhere. Thanks,
Dan

Wifi Drop-out when iMac wakes from sleep

My iMac does not connect when waking from sleep. I have to turn the airport off and on every time. Its been doing it since last October when i installed Lion. I had hoped it would be fixed with an update but no such luck. I have seen similar posts but no suggestions to fix it. Anyone have any ideas?
