Hi there i am confused about the actual requirements that Macbook / Macbook Pro and Macbook Air require in order to complete a clean install..
If the MB/MBP/MBA came out with 10.8 pre-installed can i use a bootable USB stick loaded with 10.8.4 to do a clean install?
Some people have told me that you can only re-install to the same version ie..10.8 for 10.8..and not 10.8 to 10.8.4 etc
Also why does the Macbook Air and retina displays not allow a clean install from any bootable USB stick?
Thank you in advance..
