bootable USB drive with OS Installer
My MBA comes with Mountain Lion installed. I like to have bootable USB drive with OS Installer handy. Do I have to pay to download Mountain Lion Installer?
MacBook Air, OS X Mountain Lion (10.8.2)
If you want to make a bootable USB disk, open App Store > Purchases and download Mountain Lion. Then, use Lion Diskmaker to create a bootable Mountain Lion disk > http://blog.gete.net/lion-diskmaker-us/
