    [SOLVED] Re: Swap Command/Control on 15.04?

    Yes, this has been made more difficult in recent versions of Gnome and Unity - supposedly, they want users to concentrate on their real task (admire the sleek graphics) and not fiddle with their...

  7. [ubuntu] Re: imac runs hotter with Ubuntu 12.04 LTS & other questions

    That's because you are looking at the wrong readings... The critical temperature is the GPU. You can get it with this command:

    [ubuntu] Re: Booting Ubuntu from a Mac Mini

    well, sorry to say, but again: depends on what you mean when you write "My intention is to move that hard drive to my Mac mini." If you simply want to take the same drive and reformat it, that...

    [ubuntu] Re: Booting Ubuntu from a Mac Mini

    Depends on what you mean when you write "bootable usb hard disk." If you want to boot an (intel) Mac from an external hard disk, it must have a GUID partition table. If you install grub-efi to such a...

    Highly unlikely. From what I've learned in the past, for the boot sequence on the Mac, the memory card is treated like a USB drive. Macs will only boot from USB drives if they have a GPT partition...
