I need to repair some problems on my disk. Mac is running very very slow.

I follow instructions and restart the computer with Cmd+R.

I get the OSX Utilities up ok but when I select Disk Utility from the 4 options nothing happens

to allow me to proceed?


Can you help.






iPhone 3GS, Mac OS X (10.7.2)

With a MacBook, you don't have a lot of other things to try. But DO try Safe Mode.


Hold down the Shift key at Startup. This will take five minutes to do a Disk Utility (Repair Disk), then put up a Login Screen that demands your username and password, even if you normally auto-login. It says Safe Mode in RED. The System will be running with minimal extensions loaded. so some things may not work properly.


If it manages to make the repair, you may be OK going forward. But this should push you into thinking deeply about Backups.


If you use Time Machine under 10.7.4 or later, it will make another copy of your Recovery_HD on the backup Volume.


If your drive does not perk up immediately, you should buy a new drive to have one ready in case the old one continues to decline and dies. An external enclosure, or just a simple USB "non-enclosure" can be tremendous help in making the transition to a new drive.
