Apple-ID fixing

Video guide here (Use SMBIOS iMacPro1,1)

  1. Modify the MAC address. You can use a random multicast MAC address generator.

    • With the basic.sh script, just edit the script and modify the MAC address (search for "mac=").
    • With virt-manager, paste it into the template generated by make.sh. While I was editing the template, I also used uuidgen and pasted that in there for good measure. Then import the template with virsh define whatever.xml.

  2. In the macOS Finder, look for EFI in the left bar under Volumes. If it isn't visible you will have to mount it:

    • Open the macOS Terminal and type diskutil list and look for the disk/partition location of the EFI. (There may be more than one.)
    • Type sudo diskutil mount diskYsZ, using the disk/partition location name where you see EFI. It should look like this: image

  3. Download GenSMBIOS and generate a set of serials for the mac model shown under "System Report" ("iMacPro1,1").

  4. Locate the plist file at /Volumes/EFI/OC/config.plist. Insert the generated serials into generic section in the appropriate places.

GenSMBIOS Valueconfig.plist
TypeSystemProductName
SerialSystemSerialNumber
Board SerialMLB
SmUUIDSystemUUID
  1. You can edit it by hand or use ProperTree for this.
  2. Reboot.
    • Sequoia only: In this version, it seems macOS detects the VM and "blocks" the apple ID. To trick macOS the default opencore config disables the flag "hv_vmm_present".
    • Due to this, make sure the flag hv_vmm_present set to 0 by runnning the command sysctl kern | grep 'kern.hv_vmm_present'. If it is not, try updating your local repo, and if this still does not work, open an issue or join the discord server.
  3. You should be able to log in with your Apple ID now.
