Eric.C Posted December 20, 2008 Share Posted December 20, 2008 I've read that you need PC EFI v9 before updating to 10.5.6. I currently have v8, and downloaded v9 (only 1 file named boot). Do I just drag it into the root folder of Macintosh HD to install it? or is there some other way of updating from PC EFI v8 to v9?
