Hi, I created a pendrive with MAC OS 10.8 I tested it to Mac Air and Macpro and it works OK. Live MAc runs and from boot pendrive. But when I try to boot a miniMac with that pendrive a circule with / appears and the screen and I cannot boot it. I am sure that pendrive is OK, because as I said with other computer it boots. And MiniMac is new computer. It is perfect. When I press Alt to get boot menu, I can see the pendrive, but it doesnot run. Any idea what could be the problem?
