Apple released "Mac OS X Update 10.4.3" on Halloween, October 31, 2005.
I had previously advised my Macintosh friends to hold off on upgrading their own Macs until I have tested it. Now I have ran it on my PowerBook 12" for over a week without any problems I believe that it should be safe for my Macintosh friends to upgrade their respective systems.
NOTE: The following steps are the recommended steps to upgrade any Mac OS X versions. It is especially important given the number of fixes that this Apple update included.
- Backup all you important files. I had always advised everyone to make frequent backups. You will thank me when time comes to recover from one of those backups.
- Run Disk Utility (Location: <user folder>/Applications/Utilities/) and perform a Repair Permission on your boot hard drive
- Download Apple's "Mac OS X Update 10.4.3 Combo" from Apple's web site (it should be around 109MB in size)
- Restart your Mac in Safe mode. To do so, all you have to do is hold down the Shift key while restarting
- Mount the disk image (the .dmg file) of Mac OS X Update 10.4.3 Combo and then execute the update, following the instructions on the screen
- After the installer ask you to restart your Mac, run Disk Utility (Location: /Applications/Utilities/) again and perform a Repair Permission on your boot hard drive
