Mac won't sleep after adding Kensington Wireless Mouse

I've added a Kensington PilotMouse Laser Wireless to my system and now it won't sleep, without first switching off the mouse. Kensington has no info on this, is there a workaround?

The "sleep" that you describe is not sleep. Your mac has crashed but since it thinks it is sleeping there is nothing in the crash logs.
Sleep on modern computers is not just a hardware shutdown. Because X and XP are server based kernels they are designed to run 24/7 and do what they can to keep it that way. Deep sleep requires an orderly shut down of processes and loading their status into memory so that when it wakes, all is as it was.
There are many things that can prevent sleep. Usb devices are designed to wake a mac on a change of state (doing something). When my mac did what yours did the only fix for it was an erase and install. I tried all the other solutions but the only one that worked was an erase and install.
If you care to try some of the "fixes" then here are some.
Reset the pmu.

Powerbook won't sleep after OS install and update

I replaced the original hard drive with a new drive, installed OS 10.4 from the boot disk, updated to 10.4.11, replaced original apps and user folder via Carbon Copy Cloner. Machine runs great, but won't Sleep, either from Apple menu or closing the lid, wakes up in 1-2 seconds. Had no problems prior to swap.
Airport and Bluetooth are off, nothing plugged into the port. Trashed bluetooth.plist and restarted. Checked Energy Saver, set to "drive sleep when possible". Nothing new showing in StartUp items, or Activity monitor. Same whether battery or plugged in.
The only diiference is that I typo'd my user name. I created a new Sys Prefs/Account, then deleted the old account. I've run Apple Disk Utility Repair/Permissions amd Onyx maintenance. Nothing scheduled to run in CCC or Onyx.
Any advice is appreciated!

Thanks BGreg,
I did Software Update via WiFi. It took multiple passes, as Java would install, Software Update would recheck, and then download the next version. Took about 5 passes, with 2-3 restarts to have everything updated vai S.U.
I used a generic Tiger disc as the boot disc.

Mac Won't Boot after Boot Camp Windows Update - Macbook Pro Mid 2010

Hello All, and thanks in advance for any assistance you can provide.
I have a Mid 2010 Macbook Pro. Last year I upgraded the RAM, then this year I decided to upgrade the hard drive to an SSD-hybrid. Everything went perfectly smoothly with both upgrades, and I was a happy camper.
I had also installed Boot Camp with Windows 7 and everything worked perfectly. Then last night, I boot in to Windows 7 and it gives me a 'service pack update'. After installing it, I had to reboot my computer. Rebooted it and it accidently started booting OSX. No problem, I thought. I held down the power button, and booted back in to Windows. The service pack installation continued and it had me restart my computer an obscene amount of times during the installation. This is when I initially thought "this is weird".
Finally the service pack installs, and I'm able to use Windows 7 again. Then I shut down the machine and tried to boot back into OSX. No dice.
Here's how the OSX booting process goes:
First, the Apple logo appears, then what appears to be a progressive loading bar at the bottom. After a few seconds, the loading bar disappears. Then it's just at the Apple booting screen with the spinning wheel/gear and sits there indefinitiely. I let it sit there for over an hour last night and nothing happened.
Any suggestions? I tried resetting the NVRAM and the SMC.
Thanks so much,
dlevv

It looks like a hard disk problem. Press Command and R keys on boot, open Disk Utility, select Macintosh HD in the sidebar and repair your drive

Display won't sleep after being in suspend once.

When rebooting the computer, the display sleeps after set interval and can manually be put to sleep using shift+ctrl+eject.
However if the computer goes to sleep or I myself close the lid to make it sleep, the display won't sleep again.
The display won't sleep after set interval in power settings and when I press shift+ctrl+eject the keyboard backlit turns off but the screen stays on.
The only way to make it sleep is to close the lid.
I have tried resetting SMC and NVRAM but to no avail.
I have the first generation aluminium macbook.
Does anyone else have this problem?
I have had this problem both in 10.6 and 10.8

Mac won't sleep - Reason?

I am trying to figure out why my mac won't sleep.
I have run this command in the teminal (pmset -g assertions) and this is what I get back. If anyone can let me know what the problem is I would appreciate it. I have disconnected everything from the machine such as firewire, usb cables etc. But the computer will not sleep on its own. It does when I initiate it but not by the automatic function in energy saver pref pane.
Thx
Felix

If it is'nt the card, this may help;
If your Mac happily goes to sleep but won't wake up--Hold down the power switch to force-reboot your machine and get it running again.
Don't worry-your Mac isn't narcoleptic. Its Open Firmware system or NVRAM (nonvolatile RAM) is likely corrupt, and your Mac can't remember how to wake up.
Restart your Mac and immediately hold down the Command-Option-O-F key combo until you see a somewhat intimidating command-line display that ends with the Open Fimware prompt. Type the following lines:
reset-nvram
press Return on keyboard
set-defaults
press Return
reset-all
press Return
Your Mac will reboot. Once it's running, put it back to sleep to test. If the problem recurs your Energy Saver preferences may be the culprit. Delete the com.apple.PowerManagement.plist file (go to Finder/Hard drive/Library/Preferences/SystemConfiguration)--don't worry, your Mac will regenerate a new one--and then restart to see if that rights the wrong.
Still did'nt work? Might be time to call AppleCare or see an Apple Genius or a technician.

Mac won't restart after updating to OS X Mountain Lion

Mac won't restart after updating to OS X Mountain Lion. Please help?

Like what happens? Is it just spinning?
If you've waited sufficiently long (say 10 minutes) you could just hit the power button which will do the trick. A little more gentle would be to open a terminal window (if you can) and type 'sudo reboot' (without the quotes) and enter your password when it asks. That will do it too.

Mac won't boot after power chord became unplugged accidently.

Mac won't boot after power chord became unplugged accidently.
I have a Mac Mini running very latest version of OSX. I was making a recording with QuickTime; when I needed to plug in a USB recording device into the back of the Mac Mini, as I pulled the Mac off my shelf to do this, the power cable came out and the Mac lost power.
I plugged it back in and powered up the Mac. I get the grey screen with Apple logo and the spinning grey wheel; then it goes to a blue screen (as usual) and I get the "starting OSX..." progress bar. When the progress bar finishes, I'm left with a blue screen only, no dock, no apple icon at top left, nothing across the top, no nothing.
So far, I've booted from the original disc and repaired the permissions as well as the disc, then re-booted, but same old blue screen.
I have another iMac G5 machine, so is there any way I can at least retrieve the important HD files from the Mac Mini to my G5, before throwing the broken Mac Mini away?
Can anyone advise please?

Hi, Nigel.
Not to differ with my colleagues here, but there's an important question that wasn't asked.
1. You wrote: "So far, I've booted from the original disc and repaired the permissions as well as the disc, then re-booted, but same old blue screen."Did Disk Utility report any errors it could not fix when you ran Repair Disk? I suggest you run the procedure specified in my "Resolving Disk, Permission, and Cache Corruption" FAQ. Perform the steps therein in the order specified.
2. You may also want to run the Apple Hardware Test that came with your Mini to be sure nothing shorted when the power cable was removed from the computer. I've seen it happen, hence I usually recommend removing the power cable at the wall before disconnecting the power cable from the computer. See my "Apple Hardware Test" FAQ.
3. Repair Disk gives your Mini a clean bill of health, the blue screen may be the result of some Startup or Login item that was corrupted due to the sudden power outage. My "Troubleshooting Startup and Login Items" FAQ can help you pin that down if such an item is causing the problem and may help you avoid and Archive and Install.
4. If you elect to go the Archive and Install route, see my "General advice on performing an Archive and Install" FAQ for some important tips on this process.
5. As FYI, this is the kind of problem that makes one glad they've implemented a comprehensive backup and recovery solution. For advice on the backup and recovery solution I employ, see my "Backup and Recovery" FAQ. Computing without a comprehensive backup and recovery solution is like driving without auto insurance.
Good luck!

Mac Mini Won't Sleep after installing 10.4.6

My Mac Mini wakes itself up after just 1 minute of putting it to sleep mode. I've tried restarting my mini, and tried quitting all apps and disabling airport and bluetooth- but it still won't sleep! Anyone else experiencing this problem, I didn't have this problem with 10.4.5 and I've installed no other software since then...

This is for a Mac that won't sleep.
First, read things in Apple doc.#25801 on sleep settings.
USB devices and hubs often cause Macs to not sleep or wake quickly from sleep (notably HP printers and scanners, HP all in ones, and Cannon scanners). Disconnect all USB except for keyboard and mouse and try. If it sleeps, add one back at a time testing after each one to find the culprit.
If you've set your Mac to recieve faxes, it may not be able to sleep. It might also have a damaged preferences file.
If you use your Mac for faxing, open System Preferences. click Print & Fax, click the Faxing tab, and uncheck the Recieve Faxes On This Computer box.
If that does'nt work or you've never faxed on your Mac, go to Finder/Hard Drive /Library/Preferences/SystemConfiguration and delete the com.apple.PowerManagement.plist and com..apple.AutoWake.plist files (if your Mac asks, type your admin. password).
If the latter file isn't present in the folder, go to user name(probably your name)/Library/Preferences, delete the com.apple.systemuiserver.plist file, and reboot your Mac.
Hope this helps!
P.S. One member here reported this (Michael Gleason);

tomhorvat adds this; After few days of messing around I found out that I had desktop background (wallpaper) set to change every 1 minute.
After unchecking "Change picture..." in system preferences (under Desktop/Screen saver), my powerbook went to sleep all by itself.

Any ideas how to solve?

You can go into the OS X Server Forum and search for this issue. I think there are some discussiom threads that discuss it and you can read some of the solutions.
I'm also running Mountain Lion 10.8.2 and OS X Server on a Mac Mini and it won't sleep if I have the File Sharing, VPN and Printer Sharing services running. To me, this is a good thing as a server is usually available to client machines 24x7.
I did experiment and turned off each service one at a time to see which ones deny the sleep function and I found all 3 do.
Here's an example from my server. The bold entries are the culprits for my server.

Macbook Pro won't sleep after updating to 10.4.11

Hi,
I just updated to 10.4.11 reluctantly from 10.4.9 as whenever I do update I always have issues...I basically just went to software update last week and updated to everything I could. I've just been reading the forums and noted that updating is not always that easy...
Well basically my computer won't sleep if the lid is left open, this is IMMENSELY annoying since I often leave my desk to work on drawings, and I don't want energy being wasted like it is at the minute. Call me picky but I just want my computer to work.
I've reseted the PRAM, (option, alt, p and r), closed all applications, etc, but no luck...
Its a 2.2ghz MacBook pro, 2GB. Thank you in advance
Neal

The important thing for the future imho, is to always Repair Permissions before & after any update... seems to ward off most of these problems. Of course that is only good if the disk is Verified once in awhile.
Using Disk Utility in Mac OS X 10.4.3 or later to verify or repair disks...
http://docs.info.apple.com/article.html?artnum=302672
About Disk Utility's Repair Disk Permissions feature...
http://docs.info.apple.com/article.html?artnum=25751
In fact I'd start with those 2 now, if that doesn't help you may need to reapply some updates by getting them directly from apple>downloads.

Insomnia - - My Mac won't SLEEP

Hi folks,
I just re-installed OS 10.5.4, ... and began to have a couple buggy behaviours:
Primarily, my computer won't respond when I try to put it in SLEEP mode.
Also, there is a funky little 1/4" square that appears in every window that opens. Clicking & dragging over it makes it go away, but it then reappears on the next open window.
p.s. In an attempt to 'fix' these anomolies, I downloaded the upgrade to 10.5.8 but this didn't help.
Any ideas ????? (This is my second post... with no responses).
Thanks,
P

This is for a Mac that won't sleep.
Here is Apple's KB article HT1776 with their tips.
Mine follow;
USB devices and hubs often cause Macs to not sleep or wake quickly from sleep (notably HP printers and scanners, HP all in ones, and Cannon scanners). Disconnect all USB except for keyboard and mouse and try. If it sleeps, add one back at a time testing after each one to find the culprit.
If you've set your Mac to receive faxes, it may not be able to sleep. It might also have a damaged preferences file.
If you use your Mac for faxing, open System Preferences. click Print & Fax, click the Faxing tab, and uncheck the Receive Faxes On This Computer box.
If that doesn't work or you've never faxed on your Mac, go to Finder/Hard Drive /Library/Preferences/SystemConfiguration and delete the com.apple.PowerManagement.plist and com..apple.AutoWake.plist files (if your Mac asks, type your admin. password).
If the latter file isn't present in the folder, go to user name(probably your name)/Library/Preferences, delete the com.apple.systemuiserver.plist file, and reboot your Mac.
Hope this helps!

I ran the update to 10.4.4 today and now my display will not sleep. Since then, I have:
1. Ran the fix permissions utility
2. Restarted, zapped p-ram
3. Deleted the preference file in /Library/Preferences that houses the energy saver configuration, then reconfigured.
Any other ideas? I did not change any of my settings after running the updater and this had been working fine since purchasing the computer.

A number of sleep-related issues can appear after incremental Mac OSX updates, including the inability to properly go to sleep, problems waking from sleep, and having your display go to sleep without your Mac going to sleep. The most common culprit is Bluetooth. Try these tips to fix your sleep problems.
WAKE UP
In System Preferences>Bluetooth, uncheck Allow Bluetooth Devices To Wake This Computer. If you are using a Bluetooth mouse and keyboard, you'll have to wake your Mac by pressing the power button.
FILE CORRUPTION
Your Bluetooth preference file may be corrupt-you'll need to delete it. Turn Bluetooth off, then go to the /Users/user name/Library/Preferences folder. Look for a file called com.apple.Bluetooth.plist and trash it.The OS will create a new preference file when you enable Bluetooth again.
ENERGY SAVER
If you have issues with a Mac or display that goes to sleep at inappropriate times, you may have a problem with Energy Saver. Delete the following .plist files and restart:
-/Library/Preferences/SystemConfiguration/com.apple.PowerManagement.plist
-/Users/username/Library/Preferences/com.apple.systemuiserver.plist--(username is your name or System Administrators name).
-/Library/Preferences/SystemConfiguration/com.apple.AutoWake.plist
A restart is very important after deleting these plists. After a reboot your Mac will then generate new ones.
In some cases, running MacOS X's cron tasks-maintenance that the OS performs automatically if you leave your Mac on 24 hours a day-can resolve many sleep problems. If you don't want to leave your Mac on, you can use MacJanitor, Yasu, or OnyX free at Versiontracker.com.
Some, in these forums, have had luck fixing sleep issues downloading the Combo update from this site (yours may be corrupt), not Software Update, disconnect all firewire + USB devices except keyboard + mouse, Repair Permissions, re-install update, Repair Permissions again + try.
Yours would be the 10.4.4 Combo update. Others reading, download the combo update that applies to you!
Cheers!

HT1776 Mac won't sleep automatically

Despite attending to all of the issues mentioned in this article, my machine won't sleep automatically. However, I've found that using SleepNow (http://www.dragonone.com/products/macosx/pleasesleep/) works like a charm. Apple should do something similar.

Wow thank you. I have been struggling with my macbook for about a year with this issue. Even after complete reinstall of the system, on new hard drives etc. nothing seemed to work. It drove me nuts coming back to my computer 2 hours later to find it completely dead because the computer would. not. sleep. ever!
This free simple tool took about 15 seconds to get on and running, and problem gone. Thanks so much.
Apple get on this...
