I am not educated on this issue, but: are you using a smbios.plist in /Extra? I think you should (iMac 9,1 or similar)
Have you tried Mu|tibeast - does it offer a app-store hack?
No, I have not tried Mu|tibeast, but it might be an idea. Though I don't know if it has an App-Store hack. I do not have a smbios file - that is one of the last things I've to do. I'll try those two, see if it helps. I know it's obscure, but do you have any experience with Corona on hackintosh and/or do you know anything about app signing for iOS on a non-Apple Mac?
I am now succesfully logged into the app store, after extracting the Ethernet card's EFI string w. EFI studio, adding the following code into org.chameleon.Boot.plist<key>device-properties</key> <string>4b00000001000000010000003f0000000100000002010c00d041030a0400000001010600041c0101060000007fff0400160000006200750069006c0074002d0069006e0000000500000001</string>restart, app store, login
Before it wouildn't work ("Device not recognized")
Yeah, this is what I've endlessly tried, and it has not helped.
