raymond81 Posted November 21, 2006 Share Posted November 21, 2006 I'm new here. Just try to install OSX to my Toshiba laptop, using 10.4.6 JAS DVD. Everything goes fine until 'optimizing system performance' stage. It stop at 50%. i don't know why this can be happened? Can anybody help me? I had done for the disk utility and the customization part before starting the installation. And i did try for several times, it failed at the stage too.
