Ubuntu provides documentation, but unfortunately it only applies to modern Macs (specifically, those without optical drives). Older Macs don’t have the capacity to boot MBR-partitioned USB media, and you must use an EFI loader to do it. See: https://sevenbits.github.io/Mac-Linux-USB-Loader/
If you have a modern Mac, then the standard procedure works: just write the contents of the ISO onto the device using dd, and then boot up in either BIOS or UEFI mode from the boot menu (hold Option at start). The latter is preferred (“EFI Boot” using the fallback loader) but the former is sometimes required (Macs call it “Windows” regardless of the underlying OS). Is anyone confused yet? Sorry about that. :) I won’t vouch for the performance of Ubuntu on your hardware. I will say that having sighted help around is a distinct possibility, if only to verify that your image is booting. -- The following information is important for all members of the Mac Visionaries list.
