I installed Leopard on my 700 mhz iMac G4. I know Leopard doesn't officially support this machine, but I used LeopardAssist to install it. I figured the machine has enough ram (1 gig) and a CoreImage supported graphics card, so it should run good enough for simple email and web browsing. I wanted Leopard on this machine instead of Tiger so I would have the same OS as my other macs (it's easier to troubleshoot when you have the same OS on multiple machines). THe only problem seems to be that I keep getting the spinning beach ball every 30 seconds or so and it lasts for 5 seconds and locks up the system while it's spinning. These beach balls don't appear to be related to low RAM (the system is not paging, and 1 gig seems to be enough to run Mail and Safari). Does anybody have any idea what might be causing this or how to reduce the number of beach balls? I can't relate them to any one system process or anything in specific. Any tips to make LEopard run better on an old system would be much appreciated.
