How to fix the OSX Leopard Set up Assistant Loop Bug.

Today, my G5 (Leopard) started displaying the Set Up Assistant everytime it booted. Even after completing setup it was impossible to access the GUI. It was held in a continuous.

If you get caught in the Leopard Setup Assistant Loop Bug, here is the way to get your Mac booting again with no loss of data.

  1. Boot into Safe Mode by holding down the shift key just after you hear the first boot sound. This takes an eternity so be patient.
  2. Don’t log in to any account. Instead press the back arrow key once (this will highlight an account).
  3. Then click the restart button.
  4. Now just wait while your Mac performs some updates and then reboots as normal again.

Even Macs break occasionally / rarely.

  1. so i accidentally deleted the universal binary files and then proceeded to reset my mac book without an install disk as my disks are at my parents house. i started up single user mode and thought i entered everything correctly before i reset my comp i read that i have mac os x 10.5.8 any solutions to make my computer like new?

  2. many thanks for finding the fix for my wifes imac, my quadcore g5 and our two mac pro’s were not affected. Thanks again….this goes to prove the mac community rules!!!
