I made a bootable USB pendrive with Mac OS X Snow Leopard on it. On my Macbook Pro 2007, this USB pendrive booted and I was able to install Mac OS X from it. I have tried to do the same thing with a Macbook Pro Mid 2010. I powered on the computer, pressed Alt key, selected the pendrive from the Menu but then nothing happened.
Has anyone managed to boot up from a USB pendrive containing Mac OS X ?
