MacBook Pro Glitching Fix

Just fixed an annoying problem that started when I upgraded to Lion. When dragging something to the dock from finder, or from a stack to Finder there would be a flash of strange coloured graphics at random points around the screen. It’s gone too fast for me to do a screenshot but I may try to get a small video of it.

Anyway, the fix is easy and involves turning the dock from 3D to 2D mode.

The Terminal commands are as follows:

defaults write com.apple.dock no-glass -boolean YES
killall Dock

The first command sets the Dock into 2D mode, the second command resets the Dock to allow the changes to be seen.

Below is the About This Mac screen. It’s an old (Powerbook G4 Style) MacBook Pro, Core 2 Duo.

Now I just need to find out why it takes so long to boot up.
