First restart may be longer than usual Note that your first restart after installing Mac OS X 10.4.3 may be longer than usual -- up to 10 minutes or more on some system installations.
The stall is most likely to occur after the startup progress bar shows completion, but fails to proceed to user login.
In some of these cases, the startup process is only temporarily frozen, and will continue after several minutes of waiting. After the first, abnormally long restart process, future restarts may return to normal speed.
General purpose workarounds (try these first) Two workaround routines will solve many of the issues that are indirectly caused by Mac OS X 10.4.3 installation (i.e. not due to bugs or flaws in the update, but pre-existing system conditions that may be triggered by the updater process).
The routines are as follows:
Delete kernel extension caches, other caches for some issues A number of common issues that crop up after incremental Mac OS X updates can be resolved by deleting specific cache files -- specifically kernel extension caches -- and restarting.
This can most easily be accomplished with a shareware utility like Tiger Cache Cleaner, but also bears a manual process which involves dragging the following files to the trash:
com.apple.kernelcaches (a folder in /System/Library/Caches)
Extensions.kextcache (a file in /System/Library)
Extensions.mkext (a file in /System/Library/)
com.apple.ATS (a folder in /Library/Caches/)
Files that start with com.apple.LaunchServices (in /Library/Caches)
You will be prompted to enter your administrator password when dragging these files to the trash. You may need to restart after moving them to the trash.
