I spent the day making sure that my system and data disks were both clean as far as "Disk Utility" and "DiskWarrior 3.03" were concerned. I then used "Carbon Copy Cloner" to duplicate my system disk to a new drive (thankfully). Then I upgraded from 10.3.9 to 10.4 (I bought 10.4 the day it was released, so it's base 10.4). Once the system was rebooted, I started poking around and realized that I didn't have the upgraded X-Windows installed, so I went into the Optional Installs and told it to install the Optional Applications. I believe I told it to install the upgrades for everything except for iTunes. Shortly after I did that, I crashed. Rebooted from my utility HD, ran "Disk Utility" and "DiskWarrior" and everything seemed fine, so I rebooted to 10.4 again, and promptly crashed. Rebooted again, logged in as root this time, started downloading the 10.4.9 combined updater and a couple minutes later crashed. At that point I pulled the system disk, swapped it for the copy, and I'm once again running 10.3.9. Would installing the 10.4 versions of "AddressBook", "iCal", iChat", "Mail", Oxford Dictionaries", "Safari", or "X11" (like I said, I don't think I installed "iTunes") cause instabilities on a system that's been running 10.3.9 and was up-to-date with the exception of the last two months worth of updates?
