i want to start a thread about how to take care of your macintosh because i haven't found any answers, searching. - it arrived with a leather shred, and from time to time i clean the screen with it - i use a the program CleanMyMac to clean system but i don't recommend because i don't know if its a good idea - i schedule it to go to sleep when its sure i dont use it, like nights during the weekdays and auto wake up in the morning - the cooler begin to make like a broken noise, so first i turned boinc from 100% to 20%, then uninstalled it completely, i also had to give up flurry screensaver, so the cooler doesn't have to roll at that high speed. - the dvd combo drive, at first didn't wrote anymore, and then didn't read. i bought a cd cleaner cd and used it. i succesfully wrote a dvd this week. - i organize my files using MuCommander, i use its directories, like My Documents, My Music, My Videos, Downloads. When i have files that i don't want to trash because i might need later i barry them in a folder with current day as a name. - i bought a large external hdd to keep at least 30 gb free on the mac hdd. I don't know what more to say. - i turned off in system things i don't use like bluetooth. - it crashed once and i sent it in service, i came back very nice and clean on the outside, now its dirty again, i have no idea how to clean it. - i dont use an antivirus. - i enabled Guest account so if anyone else wants to use it, be my guest. I dont know if for my account if i should have admin rights or standard? whould it work faster? - firewall is on. anyway, What have you done for yr mac to have a good and longer life?
