Core Sync is preveing my computer from sleeping or shutting down- why?

Is there a fix for this?

Can you quit Mail normally or do you have to force quit it? If you don't want to lose your e-mails, go to Mail/Mailboxes/Export Mailbox. You can put them on your desktop for now. I would then try deleting your account and then setting it up again.
Who is your e-mail provider and are you using IMAP or POP?

When waking from sleep, it shuts down

I use the energy saver to put the computer to sleep when I'm not using it. When I hit a button to "wake" the computer, it starts to spin up but then shuts down.
I was told by Apple (when I still had my call-in protection plan) that this was because there was no room on my hard drive. This first happened when I had about 1 GB left (60GB drive). I have subsequently bought an external drive on to which I have moved my music files and now have 25+ GB, so that should no longer be an issue.
Any ideas?

USB scanners are generally a red flag for sleep-related isuues but usually in terms of failing to wake or failing to sleep, not shutting down instead of waking up. You can check if the peripheral hardware is involved by disconnecting all peripherals other than keyboard and mouse, Starting Up in Safe Mode (to disable any peripheral drivers), and seeing if you can then sleep and wake the Mac without the shutdown problem.
The system.log messages indicate you have the Mac set to use a Virtual Private Network (VPN); I'm not familar wnough with that to be sure if it affects the wake-from-sleep issue. You may want to post that snippet from the system.log along with a statement of the problem in the Using OS X 10.4 Tiger forum part of the Apple Discussions in order to reach a broader audience than in the eMac part of the Discussions.
The 'SystemUIServer not responding' message may be helped if you try this:
-- trash /Library/Preferences/SystemConfiguration/com.apple.PowerManagement.plist
-- trash /Users/[username]/Library/Preferences/com.apple.systemuiserver.plist
-- reboot while resetting PRAM
To reset PRAM, restart, as soon as the screen goes dark, hold down command-option-p-r until you hear three sets of chimes, then release the keys and let the Mac finish starting up. You may need to re-do some System Preferences settings after resettings PRAM (see What's stored in PRAM?)
BTW, a viable workaround is to change the Energy Saver settings to slepp the display only after XX number of minutes, with put system to slepp set to Never and put hard drives to slepp when possible unchecked. That also ensures the Mac can perform the background maintenance tasks overnight. If you normally shut down an OS X Mac overnight or leave it in system sleep, the cron maintenance tasks cannot run in their nominal 3 am timeframe. (Display-only sleep allows the maintenance tasks to run). Tiger 10.4.2 and later will force the maintenance tasks to run after sufficient time has elapsed, but kust how long is long enough, and whether the timer is reset on shutdown, isn't entirely clear. You can leave the Mac in display-only sleep a weekend or two a month; you can manually Force Background Maintenance; or you can use a third-party utility such as OnyX to run the maintenance. Note that any system utility you use must be compatible with the OS version (e.g., use the Tiger version of OnyX with 10.4.x).

Macbook pro will not wake from sleep without shut down?

My macbook pro 2007 will not wake from sleep without holding down start button and then restarting? Is this a serious problem?

You can Try resetting NVRAM/PRAM http://support.apple.com/kb/ht1379
You can run the Disk Utility> Repair Disk from Recovery ( command R on start)
if that does not sort it I would reinstall OS X

When I import to itunes my computer sleeps or shuts down.

When I import to itunes, and work in another program, my computer either sleeps or shuts down. Sleeping is much more frequent but it's extremely frustrating. Obviously I didn't use to do this. I suspect it is as a result of an upgrade, but am unsure. any suggestions would be very gratefull accepted.

Not it. Thanks. I tried it, so thanks for the tip, but I get the same error message. That I need to authorize this computer to get the purchases. I guess it's not really an error message. But It will not let me proceed any further. Once again I have deauthorized and this is the only computer that is authorized for this account.
Then
Then and last
Pretty annoying. Any ideas?

Sleep or shut down at night?

Hi, it just occurred to me that in summer with frequent lightning storms especially during the night, might it be a good idea to shut the computer down and disconnect the power adapter at night?
I tend to use the computer plugged in during the day, with short periods of battery use, and then at night I leave it plugged in and just close the lid. Even with old PC's I did this without a problem, but with my new MBP I don't want to take any chances!
Thanks,
Karen

Thanks.. re. shutting down at night, I thought there was an issue of wear and tear from starting up so often.. otherwise it would certainly be simpler to shut down and not worry about nighttime power surges.
I don't worry about wear and tear, because although technically it might be better to run your computer at full power 24/7 to avoid premature wear from thermal and power cycling, realistically nearly every Mac user either sleeps or shuts down their laptop at least once a day whether that's at night or merely to transport it (since it is a laptop after all) and therefore powering off is the norm, and it is not causing mass early laptop deaths.
We are also weighing leaving the computer plugged in versus the potential damage from a lightning strike, and we're saying the potential damage from sleeping or shutting down at night is assumed to be less severe than that of a direct lightning hit.
Re. sleeping the computer all night and draining the battery, I do that once a month to calibrate the battery, but isn't it recommended to not drain deeply too often?
You are right that is is recommended to not do deep discharges too often. But an overnight sleep does not drain the battery that far, maybe a few percent. What I didn't mention is that if your battery is new and fully charged, it will probably last around a week in sleep mode. One night off the charger isn't going to drain the battery unless, as I mentioned, it's an old battery with a fraction of its original capacity.

Sleep and Shut-down menu commands

Our 500 MHz Power PC G3, upgraded to system 10.4.6, is a great machine and a real work horse for us. However, it has been acting up lately. The apple symbol drop down menu command that puts the computer to sleep, restart, shut down etc. will not respond. The key board commands for sleep etc. also don't work. I tried the Disk Utilitly- First Aid, both Disk Repairs and Permissions. "No repairs were necessary" for both. I even reinstalled OS 10.4.6 which seems to have complicated the problem and ate a big chunk of our precious little harddrive memory. Now every time I start up I get the warning message, "Application Launch Failure" The applicaton "Transport Monitor' could not be launched
because of a shared library error:"8<Transport Monitor><Transport Monitor><HotSyncLib.PPC><"
Could this be the root of the drop-down menu problem?

As I said, a weak or dead PRAM battery can reportedly cause odd startup issues. If it has never been changed in six years, that's a really long-lasting battery, even if the iMac was kept on continuously.
They are pretty cheap from the right source, so you may want to try changing it.

Sleep mode shut down

i recently upgraded to 10.4.9 and everytime i put computer to sleep it shut down after about 5 min. i checked all energy set pionts and they are default to never shut down. what could be problem?

Try these diagnostic procedures:
1) Try trashing these 3 .plist preferences and reboot. Reset your Energy Saver preferences.
HD > Library > Preferences > SystemConfiguration > com.apple.AutoWake.plist & com.apple.PowerManagement.plist
User > Library > Preferences > com.apple.systemuiserver.plist
2) Do an Open Firmware reset: Hold the CommandOption+OF keys during startup. At the '>' prompt type:
>reset-nvram
Return
>set-defaults
Return
>reset-all
Return
Reset PRAM:
1. Shut down the computer.
2. Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
3. Turn on the computer.
4. Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
5. Hold the keys down until the computer restarts and you hear the startup sound (bong) for the second time.
6. Release the keys.
3) Reset your PMU.

Wake computer from sleep & sync iDisk?

I'm wanting to wake my computer from sleep & sync my iDisk at a set time in the day. Does anyone know if it would be possible, & if so how?
I thought if it could be done with AppleScript (wake & sync the iDisk) I could set iCal to run the script at a set time while sleeping which would wake the computer & run the script.

Your script will not run while the machine is idle, so you have to have some other process effect the wake up. This can be scheduled through System Preferences -> Energy Saver, or through the command line pmset, but you can't just have your AppleScript running in the background and expect the machine to wake on its own.
So you need to get a script to run your backup, and some other process (e.g. iCal) to start that script at the appropriate time.

How do I stop aluminium wireless keyboard from waking computer from sleep?

Hi
My aluminium wireless keyboard wakes my computer from sleep, at random occasions. Sometimes after five minutes, other times up to four hours. Sometimes not at all. My iMac wakes up (annoyingly during the night, waking me up as well) and screen says "Connection Lost", showing the greyed out keyboard-logo. It's not lying either—keyboard doesn't work, for about 30 sec until the stupid thing finds it again and all is back to normal.
*What can I do to stop this irrational behavior?*
Could this be a bluetooth hardware-malfunction?
(Background: My iMac has been acting this way, as far as I can recall, throughout all of the 10.6.X-upgrades—from time to time. Reason I am posting this now is that I haven't had this problem for a couple of months now, but it came back out of nowhere the other night, about a week ago. And I haven't been doing anything out of the ordinary, that I haven't done at least a couple of times during this period where it all worked fine.)
Additional information: I don't know if this has anything to do with the problem at hand, but when using the bluetooth for something other than just keyboard+mouse, say syncing my Nokia phone, the mouse always goes haywire and acts all laggy, trickling across the screen as I try to move it.

Yes, that sounded indeed like a daft question, but as it seems changing the batteries did actually solve the puzzle. I am baffled by this, as the batteries claimed to be at 40% and shouldn't need to be changed. But I changed them after reading your reply, and the problem stopped. Now, one week and a couple of days later, the problem still has not reoccurred.
For one reason or another, once batteries drop under a certain level of power, the keyboard connection will start acting up. I feel a bit silly, should have checked that bit myself before posting my question, but I'm glad this solved my problem. Thank you ajduguid.

Restore disk OS X Mountain Lion: Prevent computer from sleeping

Please help, I need to create a backup using the disk utility on my restore disk. However, the computer keeps going to sleep and corrupting the backup. How do I prevent my computer from sleeping while the imac is creating the backup?
Processor 3.06 GHz Intel Core 2 Duo
Memory 4 GB 800 MHz DDR2 SDRAM
I can not add anymore physical ram
Graphics NVIDIA GeForce 8800 GS 512 MB
Software OS X 10.8.3 (12D78)

I would recommend using a proper tool for backing up, if you want to create a bootable clone use either SuperDuper or Carbon Copy Cloner. Either that (or even better use a clone and) or use Time Machine.

I have a password problem. After importing data and settings from one MacBook Pro to a new one, I have to put my iCloud password in when re-starting, but the password from the old computer in when waking the computer from sleep.

I have a password problem. After importing data and settings from one MacBook Pro to a new one, I have to put my iCloud password in when re-starting the new computer, but the password from the old computer in when waking the computer from sleep. I want to use my iCloud password on both computers consistently. How can I fix this?

The only other place to change a password for the computer login is in Users & Groups preferences. But I don't really know enough here to fix your problem. You can try fixing the keychain:
iCloud- Frequently asked questions about iCloud Keychain
Tutorial: Resolving Keychain Issues
If you can't access your keychain, or forget your password If you can't get into your keychain file because you've forgotten your password or the keychain file appears to be corrupt, there are a couple of options.
First, if you've forgotten your password, you can use the "Keychain First Aid" utility to make the keychain password the same as the login password. This can be accomplished via the following process:
1. Open Keychain Access (located in Applications/Utilities)
2. Go to the "Keychain Access" menu and select "Preferences"
3. Click the "First Aid" tab
4. Make sure the "Synchronize login keychain password" box is checked
5. Close the Preferences window
6. Go to the "Keychain Access" menu and select "Keychain First Aid"
7. Enter your username and password
8. Click the "Repair" button
The second option is to completely delete your keychain then recreate it. This routine is useful if your keychain appears to be corrupt or otherwise inaccessible. This can be accomplished as follows:
1. Launch Keychain Access (located in Applications/Utilities)
2. Click "Show Keychains" in the lower-left corner of the window.
3. Select the problematic keychain from the left-hand pane.
4. Navigate to the "File" menu and select "Delete Keychain '(name of keychain)'"
5. Check all options for deletion and press "OK"
6. Create a new keychain by going to the "File" menu, then "New" and selecting
"New Keychain"
7. You can now make this keychain your default if you desire by selecting it, then
going to the "File" menu and selecting "Make '(name of keychain)' Default"
Login as root and perform repair In some cases, problems with keychains can only be resolved when logged in as the root user.
First, you want to enable the root user:
1. OS X Mountain Lion: Enable and disable the root user
2. OS X Lion: Enable and disable the root user
3. Mac OS X 10.6: Enabling the root user
4. Enabling and using the "root" user in Mac OS X
After enabling the root user, and logging in under this account, again open Keychain Access. First attempt repairs using Keychain First Aid, and failing that, delete then recreate the keychain as described above while logged in as root.
Persistently asked for stored passwords If you are persistently asked for passwords in various applications that you have specified should be remembered in a keychain, your "login" keychain may not be active for one reason or another.
Navigate to ~/Library/Keychains/ (this is the Library folder inside your user's home folder). Find the file named "login.keychain" and double-click it.
Failing that, select the "login" keychain within the Keychain Access application and make sure it is the default keychain by going to the "File" menu and selecting "Make 'Login' Default"
Turn off Keychain synchronization in applications having problems If specific applications are experiencing issues when accessing password-protected material, the Keychain may be to blame.
The above comes from an article published on MacFixit.com.

Change "require password to wake this computer from sleep or screensaver"

Does anyone know how to change the checkbox in sys prefs > security > require password to wake this computer from sleep or screensaver via cli?
I would like to always have this enabled, but individual users can shut this off...
Thanks

Code an AppleScript using the SystemsEvents>SecuritySuite>SecurityPreferencesObject>RequirePasswordtoWake then use the cli 'open' to run it?

Mail needs to be restarted every time I awake my computer from sleeping,

Every time I awake my computer from sleeping, Mail needs to be restarted.
Why's that?
The problem is that if I'm not aware of i it, my Mail stays offline.
Any help?
Thanks
Nico

This is a bug that doesn't affect everyone. I can't reproduce it and I don't know what triggers it. The following steps have been reported (but not confirmed by me) to work around it in some cases:
Turning off Dictation
Turning off the built-in firewall
Turning off the Energy Saver setting to allow hard drives to spin down when idle
Changing DNS servers
That's all I've been able to find out.

Woke computer from Sleep: USB doesn't work

So, I woke my computer from sleep, and now all my USB ports are dead.
I tried restarting, resetting the CMOS, removing the D-Bracket, which I had just installed (it didn't work either.). Any thoughts?
EDIT: All ports get power, none get signal.

Any further suggestions are appreciated.
Okay, with your front panel connectors, do they have a wire for pin 10 on the USB connector? That would be the one next to the blocked out keying pin (pin 9). If so, that could be causing your problem. If you remove the pin from the connector that could clear up the problem. I haven't personally had the issue, but I've seen it talked about. If your internal USB connectors only have 8 wires on them, then I don't know what to tell you...

Is the trackpad supposed to also wake up the computer from sleep?

Hello,
I am not sure if I am able to before, but right now making a swipe or even a click on my trackpad doesn't wake up the computer from sleep - although typing on the keyboard does. Is this really the case? Or can the trackpad also wake the computer? I've already tried resetting the PRAM but it would still not do the trick. It doesn't bother me much though.
Thanks!

Swiping the trackpad should also wake the computer. Touching a keyboard key that is benign is usually preferred. i.e. shift key.
