I recently updated my Power Mac G5 from Mac OS X Tiger to Leopard. I used the update option offered by the Leopard installation DVD which did a reasonable job. The process took about two hours and the machine started up without any problems afterwards. However, there were a few problems I had to sort out over time:
- The new automounter maps /home to an automount map called auto_home by default. If such a map is not available the directory /home will appear to be empty. Commenting out the according line in the configuration file /etc/auto_master fixes that problem.
- Emacs didn’t work after the update. It died with a Fatal malloc_jumpstart() error on startup. It seems that the update didn’t overwrite the Tiger Emacs binaries properly. Installing the Security Update 2008-002 fixes that problem fortunately because it contains an update for Emacs.
- Software Update refused to install the latest version of QuickTime with the rather cryptic error message The update â€œQuickTimeâ€ canâ€™t be saved. The problem could however easily be fixed by removing the contents of the /Library/Updates/QuickTime folder.
- Safari had been made the default browser. This can however be changed easily using Safari’s Preferences dialog.
- The system didn’t know my private root certificate anymore. I had to reimport it using the program Keychain Access in the utilities folder.
- The configuration for my (network attached) printer was removed during the update. Re-adding it was however easy as usual.
I hope these hints will help other people to sort out similar update problems.
