Muaitai Posted December 2, 2020 Share Posted December 2, 2020 The problem most likely is that you are using an old SMBIOS already registered to iCloud. Get GenSMBIOS and update your information with a new serial number. Quote Link to comment Share on other sites More sharing options...

Get GenSMBIOS and update your information with a new serial number and confirmed its not validated by apple. Generated a new serial with SMBIOS and still having the error.

Please help and thanks in advance. houston car service This issue might be due to compatibility or configuration problems. Here are a few steps you can consider: Check SMBIOS: Ensure that you're using a compatible SMBIOS definition for your system. Using an SMBIOS that closely matches your hardware can help with Apple ID login issues. Networking: Verify that your network connection is stable and functional. iCloud services require a reliable internet connection. iServices: Make sure you've properly configured your iServices, such as your serial number, UUID, MLB, etc., in your OpenCore configuration. NVRAM: Ensure that NVRAM is properly emulated in your OpenCore config. Some iCloud services rely on NVRAM emulation. BIOS Settings: Check if your BIOS settings are properly configured for macOS compatibility, including enabling necessary virtualization options.
