As the above but also remember to both leave your Mac on over night and/or turn it off occasionally. The computer does some maintenance scheduled at night, and at start-up (see Mlsstl and the reason for restart advice from the Sfar link).
How to do defragment disk on Mac?
Please help, I'm a dummy for Mac. This is my first time that I use Mac System. I've tried "help" on tool bar and even bought a book "Mac for Dummies" but I could not find any help regarding to "Disk Defragment". If any members know how to get Disk defragment work or locate its icon please show me how to do or get it. Thank you very much.
