Hey guys. I have a (circa 2003) single 1.8GHz PowerMac G5. Since the installation of Leopard (launch day) my G5's fans speed up a lot. I only have 1GB of memory, so maybe if I boost it to 4GB (newegg.com), the G5 won't have to strain as much and therefor possibly eliminate the chance of the fans accelerating? Would that work? Also when I used to use 10.3.etc Disc Utility always worked properly and repaired my permissions. Since the installation of Leopard whenever I try to repair permissions Disc Utlitly sits there acting like its searching for something but it is not. It just sits there for hours if you leave it. It makes no sense. Any suggestions? Thanks guys. I just need Leopard working properly since my G5 can't run Snow Leopard. I just bought a new Ninja so I can't afford a new MacPro this summer. Well.. if I went to empty the bank I could. Haha.
