At first I thought it was because they made the assumption you would know how to make the drive bootable (I didn't) but then I figured out why the guide was sorely lacking. What gives it away even more is Ubuntu's lack of regards for making the USB bootable through your operating system's native partitioning program, ergo, Disk Utility or Computer Management for Windows users. So in short, the instructions are severely misleading, because any Mac user would likely assume these instructions would be for creating the bootable media to work with OS X, but it'd only work with Windows. I thought about it some more and eventually figured out that these instructions were to create the bootable drive if you're using a Mac computer, and I know this because in Disk Utility, my 4 gigabyte Verbatim USB flash drive is formatted as MS DOS (FAT) with a partitioning map scheme of Master Boot Record which is not recognized as boot media under OS X. I'm actually not surprised Ubuntu's instructions don't work for creating a bootbale USB for Mac. Yet, the folks who wrote these instructions would certainly know this fact - yet their instructions don't work. I'm not surprised because my memory is that to get a bootable drive for a Mac requires some version of the correct OS X to be on the disk.
Eventually I get an "Unrecognized Disk" error. Issued: diskutil eject /dev/disk1 and restart with Option held down.
The copy goes fine, BUT at the end I get a OS X message that The disk you inserted was not readable by this computer. Issued: sudo dd if=/ubuntu.img of=/dev/rdisk1 bs=1m

The "USB for OS X" instructions say insert USB Flash media.īut, if one were to use Disk Utility to Erase, what format is correct: FAT, ExFAT, Mac OS Extended (Case-sensitivity), or Mac OS Extended?įound the drive: /dev/disk1 and unmounted OK. I've downloaded the 12.0.4 32-bit Intel ubuntu.iso and converted it to ubuntu.img and moved to root.
