Running 0SX 10.4.8.
Everything goes as normal on start up, until the last few seconds when the desktop loads, then it goes from millions of colours to 8 or 16.
- I have tried reseting the pram
- I have restored OSX
- I have just tried rotating the screen in the display settings and it goes back to millions of colours, but when I restart or shutdown the problem comes back.
Anybody had the same problem? and how did you sort it? or anything else I could try.
