Make sure you pick the right name, or you could end up doing some damage. They will have names such as /dev/disk1s1 and dev/disk0s4 for example. Open Terminal.app on your mac and copy/paste this command (you can type it, but there'll be some more complex commands later that you might want to cut and paste to avoid errors) diskutil listįrom the output, identify both the flash drive and the 2gb partition.

Create another partition (you can choose FAT32 for this too) the same size as you want your final install to be (I have a 750GB internal disk on my mac, so I gave ubuntu 100GB of that). Create a 2GB partition on it, formatted to FAT32. Open Disk Utility and choose the internal or external disk that you're going to use. When that's finished you'll get a warning that the USB is not bootable on a mac. Choose the ubuntu iso as the source and the flash drive as the destination. Those instructions just don't work.ĭownload and install the app UNetbootin from here: įree space on an internal or external disk to boot from and install too. Whoever's responsible for the ubuntu page on this (the one I linked to in my OP) really should get it changed. However, I'm going to offer a summarized version here.

OK, so I figured it out, largely thanks to this extended thread on macforums
