The UpgradeWhile most people were probably going from Snow Leopard to Lion this weekend, I was upgrading my G1 Mac mini from Tiger to Snow Leopard. The system had gotten corrupted over the past few months for some reason. Everything became slow and the Internet connection was spotty, only going through about 5% of the time. So instead of returning to factory settings, I took the opportunity to go up 2 versions to Snow Leopard (10.6). Almost nothing is compatible with Tiger (10.4) now. When I first got the iPad, I tried to set it up with the Mac mini and it was incompatible! I ended up syncing with my Core i7 PC. Ironically, the iPad IS compatible with Windows XP... a 10-year old OS.
iTunes and MediaOne of the concerns of switching operating systems was my iTunes library and purchases. The solution was simple though. All I had to do was backup my Music folder and copy it back after the upgrade. As long as the path to all of your music and movies remain intact, you should have everything as is after the upgrade (and after you logon to the iTunes store for the first time). Your movies will even be in the same position you left them in.
iLifeThe main purpose of my Mac mini is for video editing. The $29 upgrade to Snow Leopard gets rid of the whole iLife suite though. So I had to spend another $25 on iLife 11 (on order) so I could get iPhoto, iMovie and iDVD. The new version should give me 2-3 versions of themes I was behind on too. That alone is worth $25 to me.
Windows VMAs part of Apple's backwards compatibility issues, I also had to change my VM. Previously, on Tiger, I was running Windows XP over the first version of Parallels. I switched to the free Oracle VirtualBox, which is a smaller program with the same features (same VM I used to run
OS X on Windows 7). The Windows VM acts as my home network's file server, so it's a minimal install. Out of the 80 GB total hard drive space, I only allocated 15 GB to the Windows VM. After the installation, all updates and Google Chrome, there's 6 GB free for me to move files around across my systems.
