I've looked and looked without much luck. Anyone know of a means to get Lion 10.7.5 11G63 on to a single layer 4.7GB DVD disc? 10.7.5's InstallESD.dmg is too large, coming in at 4.72GB. Lion DiskMaker 1.7 handled Lion up to 10.7.3 . I need 10.7.5 (during the install) since I use a non-EFI graphics card in my Mac Pro 1,1 and it is the only version with built-in drivers. A USB flash drive won't work since you can't see the Startup Manager (Option key) with a generic PC graphics card. I'm assuming holding the C key will work, but my old SuperDrive won't work with dual layer media. All the guides out there deal with 10.7.3 and lower.
