Hi all. being new to the mac can anyone tell me and anyone else who may be interested, what maintenance does one need to do to keep their mac in tip top shape? I've heard you have to repair permisions each month and every 6 months you have to zap the p ram. can anyone tell me exactly if there's any other maintenance one must do to their macs? I'm familiar with what one needs to do to keep a windows machine in good shape but the mac is a whole new experience. I'm enjoying the experience and I never thought i'd say it but man i'm so glad to have a mac and hardly use windows anymore. The mac is absolutely brilliant and i'm really greatful to apple for voice over and great access to the mac. I know there are always improvements that can be made but right now we have it pretty good and again thanks to the list for any assistance.
