    Independently of this, Mac OS X since Tiger indeed recognizes GPT and can work with it. Not too surprising, since that was the first version of OS X to run on Intel. But PowerPC machines can't boot from GPT.

    So in this sense, MorphOS supports everything needed to work from the PowerPC machine, and GPT is not one of them. Anyway, there should be some basic support for GPT, at least to read disks using it, but it might not work in every case.


    It shouldn't actually be difficult in theory. GPT is just a different partition and drive geometry table, like MBR, but that allows 64 bit addressing. It should be simple for MorphOS to parse this and allow the mounting of partitions as it does with MBR and APT.

    I would guess it just hasn't been a priority to add because you can't boot from GPT on any current MorphOS hardware anyway, and removable drives haven't tended to be bigger than 2TB and so can be formatted with MBR.
