I need help. I created a Mavericks install flash drive from the App Store Update using MyHack and ##### on different occasions, but with the same result: As soon as the Apple Logo shows on the screen, it instantly reboots. This is on a stock Optiplex 745 SFF with 2GB RAM a 320GB hard drive, an NVidia Quadro NVS290, 1.86GHz Core2Duo. Please help!
If it is a CPU problem, I could understand that. after doing an install from a USB drive of a retail Snow Leopard DMG, i got it updated to 10.6.8 and wouldn't download the app, because it said "Mac OS X Mavericks is not supported on this computer." It is really annoying, as I would like the latest and greatest.
