Mac Clock Freezing

Select  ▹ System Preferences ▹ Language & Text ▹ Region ▹ Region: your country. Test.

Hello, let's start with this...

One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for problem in Safe Mode...

PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive

Reboot, test again.

If it only does it in Regular Boot, then it could be some hardware problem like Video card, (Quartz is turned off in Safe Mode), or Airport, or some USB or Firewire device, or 3rd party add-on, Check System Preferences>Accounts>Login Items window to see if it or something relevant is listed.

Check the System Preferences>Other Row, for 3rd party Pref Panes.

Also look in these if they exist, some are invisible...

I'm having the exact same problem. It seems to have started just recently. Do you by chance run this program on your Mac?: http://bjango.com/mac/istatmenus/

Stuck clock seems to have become an issue for me just after updating to istatmenus newest version.

I've not attempted to re-boot in safe mode - too busy to trouble shoot now. Just popped in to see if anyone else had already found a fix. Thanks.

Ok, had to check if it was the same in 10.6, 10.7, & 10.8, but appears so, kind of...

You've probably got a couple of corrupt preference files.

Move these files to the Desktop for now...

/Users/<yourname>/Library/Preferences/com.apple.systempreferences.plist

/Users/<yourname>/Library/Preferences>com.apple.systemuiserver.plist

/Users/<yourname>/Library/Preferences/ByHost>com.apple.systemuiserver.xxx.plist

where 'xxx' is a 12 digit (hexadecimal) numeric string.

Some may also end in .lockfile in higher osx versions.

Reboot.

This will reset your Menu Bar to the default, you'll need to go through System Preferences to reset the ones you need. (If they are already checked, uncheck them first and then recheck them).

I recently had the same locked up menu bar clock. It seem to be simultaneous with the expiration of a trial version of iStat Menus. I ran the uninstall that came with the latest version and everything is back to normal.

I hope your problem is fixed as easily.

Great idea to run the Uninstaller - Just did and your fix worked. Too bad, rather enjoyed the program. However, I'd rather have accurate time. 🙂

Did you go back to the old version and if so - what are your results?

I have not had the time or desire to troubleshoot any further. I'm just happy to have my menu bar clock working properly again. Best Regards!

For me, this problem seems to have been solved by manually updating my Logitech Control Center from 3.6 to 3.7, which had not happened automatically.

My clock and Finder menu bar dropdowns had been behaving oddly, I was getting crash reports from LCC itself and from UI Server, and the computer would not wake from sleep.

Resetting PRAM and SMC had not worked, nor had deleting Scroll Reverser which had been on the menu bar.

I have had this issue for a while and I have istats program. I when to menu and there was a tab that said re-install I did that and it fixed my problem as of now.

I just ran into the same problem of the clock freezing and disappearing. I did an update of the istat menus and the problem is fixed. Thanks to those who suggested that was the problem.
