My DVD drive is broken so i really needed a live USB.
Considering that most macbooks these days do not have CDrom drives Ubuntu should serious focus on this a bit more or write off a large majority of laptops from their user base.
The long method, which is somewhat more up-to-date for people finding this now at lifehacker.com/5934942/…, works.
However, even if you go to all the trouble of getting this installed via USB or otherwise, you'll still have a lot of work to do in configuring the OS at the low-level (better be familiar with the terminal) for the trackpad and other things to function as you expect them to; much reconfiguring.
If you select "USB" and "Mac" on this download page, it gives a series of command line instructions to make a USB key which the Mac Book will boot into Ubuntu from.
I've followed them to the letter two or three times on different USB keys, and it doesn't work. If you have a newer Mac (64 bit), just remember to use the Mac iso( the bootable USB key to its own partition on your hard drive and then boot off that partition. This doesn't always work, even on the same hardware.
There's a very great deal of technical discussion about EFI etc. Apple doesn't want you to boot an OS other than OS X off USB. In particular, if you have a Mac Book Air, which doesn't have an optical drive, then the forums are filled with posts of trying the dd-to-a-partition trick and failing.but this set of instructions seems to suggest it should just work, but it doesn't. I'm increasingly unhappy with the more locked-down approach Apple is taking, and I'd quite like to start using Linux with a view to transitioning over to using it as my main operating system, but booting from the CD takes forever, runs slowly and I'm really hoping to get it moving off USB. Maybe I'm not completely sure what you're asking, but after installing the Ubuntu iso (v12.04) onto a USB stick from a windows computer, I just held alt on the Mac on boot to choose a different boot option, and the drive appeared as Windows. For Mac Book Air owners, it is strongly advised to obtain a Mac Book Air Super Drive (no, a regular USB CD/DVD drive does not suffice) and then use that to install through the usual CD route (using the Mac iso for a 64 bit install). ) to install 11.10 onto my Mac Book Air 3,1 (late 2010 model).Shame they haven't tuned it more for the Macbooks by now.This procedure requires that you create an file from the file you download.It will also change the filesystem that is on the USB stick to make it bootable, so backup all data before continuing. This answer is how to create a bootable usb key while currently running OS X. download the latest ubuntu iso (13.04 at this point) 3. hold option or command (alt or super) (i forget which) 7.The question is how to create a USB that can boot a Mac. I can boot a PC with the resulting USB key, but the Mac doesn't recognize it as a bootable device. create a live usb with "Usb Startup Disk Creator" (comes default with all ubuntu installations) 4. select efi×Comments may only be edited for 5 minutes×Comments may only be edited for 5 minutes×Comments may only be edited for 5 minutes After a LOT of trouble with various methods i finally got ubuntu 13.04 32bits working on a macbook 2,1 (mid 2007).
