Minor Eccentric Behavior

All kinds of glitches may befall you, occasionally, in Mac OS X. Your desktop picture doesn’t change when you change it in System Preferences. A menulet doesn’t open when you click it. A program won’t open—it just bounces in the Dock a couple of times and then stops.

When a single program is acting up like this, but quitting and restarting it does no good, try the following steps, in the following sequence.

First Resort: Repair Permissions

An amazing number of mysterious glitches arise because the permissions of either that item or something in your System folder have become muddled—that is, the complex mesh of interconnected Unix permissions described in Chapter 12.

When something just doesn’t seem to be working right, therefore, open your Applications→Utilities folder and open Disk Utility. Proceed as shown in Figure B-1.
