Administrators Hervé Posted August 9, 2022 Administrators Share Posted August 9, 2022 It should be obvious that if you re-use the same EFI on several Hacks, you should change the serial numbers so that you use a unique one on each of them. Think of it like the postman trying to deliver mail in a street where several physically identical houses have the same number! Just plain common sense, really.

Administrators Hervé Posted August 9, 2022 Administrators Share Posted August 9, 2022 I've no idea what you're doing or what you're talking about with programs for AMD and programs for Intel. I think you're completely off track here, most likely not knowing what you need to do and/or what you're doing. If you use OpenCore, follow the Dortania Guidance, at least read it. Or you may simply use OpenCore Configurator app or Clover Configurator app, go to the PlatformInfo or SMBIOS tab, select your target SMBIOS model and click on the Generate buttons a few times to regenerate random numbers. Copy/paste those numbers in your existing config on the relevant Hack and you'll be good to go after an NVRAM reset and a reboot. As simple as that. We've a dedicated thread on this very matter for years in our FAQ section, may be you should consult it too... At least next time you have a query.

Moderators Jake Lo Posted August 9, 2022 Moderators Share Posted August 9, 2022 there's 3 areas that you need to change System Serial number, MLB & ROM You can use Hackintool.app as well to generated for the model you're emulating Link to comment Share on other sites More sharing options...
