USB 3.0 is NOT supported by the internal firmware in the newest MacBook Pro so it cannot boot to the drive, but the Operating System itself clearly adds the support for the USB 3.0 device once it is loaded. Once the OS is fully up and running, the USB 3.0 disk shows up fine as a device in Finder, it works at USB 3.0 speed, etc. In fact, when booting holding down the option key, even then the external USB 3.0 drive is not visible on the newer MacBook, but is visible on earlier MacBook.

The USB 3.0 drive will NOT boot on the newer MacBook (but it boots fine on the earlier MacBook with only USB 2.0). The USB 3.0 drive is clearly an option in System Preferences, Startup Disk, and I can select the drive just fine. It does support USB 3.0 on the newer MacBook Pro. The USB 3.0 external case drive can be read by both machines. In some testing on a MacBook Pro with USB 3.0 and an earlier MacBook Pro with USB 2.0 (no USB 3.0) I've foundД«oth will boot to an external disk (a clone of the internal drive) if the drive is in a USB 2.0 case.

Your Mac will show you a row of icons of each volume or partition currently connected to the Mac (internally or externally) that holds a Mac OS X installation that you can successfully boot from. When you boot your Mac, immediately after the startup chime, hold down the Option key. Booting from an external USB 2.0 drive, whether a flash/thumb drive or a spinning hard drive, is, however, quite slow. I have not specifically measured drive speeds in this scenario I'm just saying that it performs quite well.ДЄs far as I know, all Macs with USB have been capable of booting from an external drive connected via USB-all the way back to the first iMac circa 1998, which only made use of USB 1.0. When booting from an external spinning hard drive over USB 3.0 on my new MacBook Pro, the external hard drive sends data back and forth to the Mac about as fast as it would if it were installed internally. I know of no reason why it would not work on a MacBook Air. Yes, I just got a new Mid-2012 MacBook Pro 13' and did this very thing over USB 3.0.
