Hi There i am having problems booting the new version of Ubuntu on my mac. http://imgur.com/a/avG2I . That is the link to some photos. On my boot screen if I just let it load the Ubuntu boot screen pops up and the computer freezes. i i select Ubuntu (advanced) then select the forth on the list. i does load but the Ubuntu load screen is blurred 3rd photo. but i can use as normal once loaded. Please any advise would be appreciated thanks
