OS X Issues

Having played around with OS X on my Dell laptop (I have a family pack Leopard license btw), I just tried to update Quicktime and ended up with the Setup Assistant continually restarting when I tried to login.
The problem was caused by the computer crashing when it tried to update, which required a “Finger of Death” restart. This inturn corrupted some cahce stuff in teh file system which caused teh Setup Assistant to run.
The simple solution was to reboot via safe mode, which I got to via pressing F8 on startup and then using the -f -v options, when it comes to the login screen, select restart. The computer should restart and install the updates and everything should be hunky dory.
