hey, i'm used to using a windoze pc where i had to regularly perform maintenance on it (defrag, clean up program folders, check disks, etc) i downloaded a version of norton sys works to try and there really isnt anything in it to do cleanup like cleansweep for the pc. do macs require some maintenance every now and then or what? if so is there a terminal command or some other hidden prgram that does this in the mac or will i have to download some software specifically for doing this. basically i want to keep my mac lean and clean. the drag and drop uninstall of many programs from the apps folder seems to easy, where are all the program files? help me out pleaseeee. thanks alot. you guys rock!
