Hi,

here's an OSX port and enhancement i made to help creating hybrid MBR partitions on GPT drive.

Code came from project rEFit: http://refit.sourceforge.net/

The package below contain the gptsync command line tool for Mac OSX Leopard.

You can download the package here:

phnix had compiled 2 years ago.

Here it's an enhanced version. With selection of partition to add, to make active, etc....

Your app was very useful for me!!

At least I have an GPT/MBR Triple Boot with OS X, win7 and Ubuntu 9.

Thank you!!

So you can't boot Windows from a GPT partition then? Windows 7 supports GPT.

Windows 7 does support reading and writing GPT disks, but not booting from them, unless the computer uses EFI for firmware, rather than a BIOS. (I've corresponded with somebody who's used a post-BIOS EFI implementation to work around this limitation, but that's currently an awkward solution that doesn't work on all computers -- I couldn't get it to work myself, for instance.) So in a dual-boot environment with Windows and a need or desire to use GPT, you must have either multiple disks (at least one MBR for Windows to boot and at least one GPT) or a hybrid MBR configuration.
