I upgraded recently from 10.3.9 to Tiger 10.4.1. More than 30 percent of the time - when I shut down the computer or restart - at the very end - I will get a kernel panic. - this is a second computer - and older G4 single-processor 450 - and I'm hardly using it at all - mainly just safari - Norton anti virus 10.0.1 and a few little programs like tex-edit etc... - I am using Canon printer driver software however... - I have shut down most of the system preferences that might be problematic... The only ones running now are my Logitech mouse software .. Q: Does anybody know what's causing these kernel panics during shutdown? - I could upgrade to Tiger 10.4.2 - however I would like to solve this problem first ... -- Thanks - RevDave CoolCat at hostalive.com [db-lists]
