Maintenance advice please

Dear members, I need some advice please. I purchased a imac this past june 08 and I need some advice on removing cache files performing repair permissions( if thats needed now ) and ways to prevent a disaster. Articles etc. Members you have done a fine job of helping people here.

In a word - Onyx. Free, and it does a very fine job.

There is no need to 'repair permissions' unless you're experiencing problems.

Thanx members.

I've just discovered that I can't open gmail notifier or look into idisk!
