I used this guide.
Worked well with the Flat-image+10.5.1 update install and Brazilmac.
I've installed your method and must give you kudos works great!
Now, questions, questions....
I can only get your method to work if the drive is MBR. In Hatchery I select Hackintosh for Arch and it works.
Now I see your sig - GUID and EFI...
When I try the EFI trick in the EFI thread, format GUID and select Intel from Arch in Hatchery, it doesn't work.
Your EFI in your sig...is it GUID or MBR? When did you apply the EFI patch, after you installed flat image? I tried this also, and after I apply the EFI patch I only get blinking cursor.
Can you update your guide to specifically and chronologically articulate how you get GUID, EFI and your method to result in an install that one could upgrade to 10.5.1 and can do future "Software Updates"?
Thanks a million in advance!!!
