TICKET ARCHIVE -> Macos X Tiger Freezes. Restarting Is Difficult.
eastmont - Sep 30, 2005 - 2:50 pm
Several times now when my PowerBook 15" (alum) running MacOS X 4.2 was just on and sitting it crashed, forcing me to hard reboot.
After restarting my Mac would not boot past the twirly thing. I booted from my Data Rescue (Prosoft) CD to unmount and verify the drive. Eventually it took but I would like to identify the problem.
Is it heat, network activity, OS X glitches, memory, kernal panic, catalog or drive issues, what is up?

It's almost impossible to provide a definitive solution without knowing anything about your system, what was running, what's installed, etc. So troubleshooting can be a bit hit or miss. I would suggest you start by doing the following:
Boot from your OS X Installer. Be sure to use the installer for the version of OS X you have installed. After the installer loads select Disk Utility from the Installer menu (or Utilities menu if using Tiger.) After DU loads select your OS X volume from the list on the left, click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer. Now shutdown the computer for a couple of minutes and then restart normally.
If DU reports errors it cannot fix, then you will need Disk Warrior (3.0.3 for Tiger) and/or TechTool Pro (4.0.5 for Tiger) to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
Assuming all is OK per the above, boot into safe mode and let the computer sit to see if it crashes. If it does, then as soon as you get it restarted use the Console app (Utilities folder) to view the console, system, and crash logs to see if there is any evidence of what may have caused the crash. Be sure to check the panic log, too, in case a panic occurred and got logged.
If the computer does not crash, then the problem is at least constrained to third-party login items or startupitems or drivers or related components. I would then download a freeware utility called AppleJack from www.versiontracker.com. Install AppleJack and follow its directions for use. Use it and see if it helps fix anything that may be causing problems. Then run the computer for more time to see if the problem has been resolved.
Random occasional freezes, crashes, etc. can be difficult to track down because you cannot pinpoint a cause or conditions that reliably replicate the problem.

Coupled with your suggestions I will follow through on the notes on the Apple site: http://docs.info.apple.com/article.h...m=106464#symp1
You are indeed correct that there are alot of variables in the way of troubleshooting this. I am discovering too that a number of Mac OS X Tiger users are experiencing and reporting similar issues, with most of these occuring after installation of 10.4+.
For now, Data Rescue got me back up and running, so until the problem returns, I will be watchful and will attempt to document the symptoms, potential cause and potential solutions.
Thanks again Steven for taking the time to respond. Your suggestions are appreciated.
