I have created USB bootable OS X installs a number of times. Just for kicks, I even install OS X on a USB thumb drive and it booted up.
The USB disk needs to be formatted as MAC OS Extended, Journaled, to make it work. What I've found when using Disk Utility is that, if you are wanting to format the whole drive, you don't necessarily need that options menu. For example, if you select the USB drive (not the volumes on it, but, the actual entire drive), then select MAC OS Extended, Journaled, it will make sure to use the proper partition scheme. However, when using the partition option in Disk utility, you should use that options button to make sure the proper scheme is selected, because Disk Utility might use the wrong scheme in some cases. This has been my experience. -- You received this message because you are subscribed to the Google Groups "MacVisionaries" group.
