I'm working on a MacBook late 2008 Unibody Aluminium with Mountain Lion on. I'm trying to mount Ubuntu 12.04 LTS 64 bit on a USB stick in Mountain Lion but it seems impossible.
I've read all the documentation on how to install it on the Ubuntu site with all the command lines etc., but it's not working. I get errors like "No mountable file detected" when trying to open the .iso file.
I'm specifically looking to have an OS that doesn't make high frequency noises. Has anyone been able to install 12.04 LTS Ubuntu on their Mac (with Mountain Lion)?
