Tip & How-To about Computers & Internet
If you are having problems with crashing slow running or an app not opening or quitting on you this should help.
First start up with the "c" key held down, this does some system housekeeping and boots in to safe boot, if this does not work or you get a folder with a question mark icon then you need to boot from a Cd (or DVD) with computer off and this works for all macs running OSX, insert the Cd into the drive when the mac is off, start with the"c" key held down until the chime or the screen lights up, when booted select language (dont worry you do not have to perform an install) the next screen has a menu along the top, select utilities and you get a new menu, select disk utility and when it has gathered information you will see your hard drive in the left of the window. Select your hard drive and then select "disk repair" run this and it will either pass the disk as Ok, repair the disk or fail it ( the repair is all about the directories where it keeps all the files, if it get corrupted the whole machine gets lost but all your information is ok) If it fails you need a 3rd party utility like DiskWarrior to rebuild your directories. Assuming this goes well then select permissionsrepair, this should be run anytime you install any software or updates (it can be run from the systems own disk utility in the applications folder but the boot disk version is better) it takes a while. When this is finished quit disk utility and from the same menu select start up disk utility and select your hard drive and then select restart.
