  1. @MTXR, A Google search for "Boot Failed. EFI SCSI Device" reveals there is a post here in this forum that points toward the solution. http://www.insanelymac.com/forum/index.php...t&p=1664097 "PS: i convert my .dmg to .iso with poweriso4.4 and it boot now thanks !" Are you using a dmg file? You need to uncompress it. Try dmg2img. http://vu1tur.eu.org/tools/ dmg2img -i <input.dmg> -o <output.img>
  2. Try this. - Browse to youtube and click on a video. - Right mouse click on the black area where the video should be playing, choose Settings in the pop-up menu. - Uncheck "Enable hardware acceleration" and click Close. Reload the page.
