Macintosh OS/Repairing Disk Permissions


Hi David,

I use OS X Mavericks 10.9.1.  What is the best way to repair disk permissions?


There many options.
Safe Mode (start with SHIFT key down)  should be done monthly

Disk Utility (Safe Mode uses this)
YASU Free  Read the Mavericks Note
ONYX Free  Avoid the Beta version
Cocktail  $20
Tinkertool System  $14

If you have a Rescue partition (some Mavericks upgrades on an existing OSX will not create it)
Boot hold COMMAND + R    not recommended, unless an emergancy

Terminal (be careful)  

Macintosh OS
