macOS uses a different identifier system. Instead of HWID, Apple operates with Apple ID + Hardware UUID + Apple Silicon Secure Enclave keys. Our Windows utility doesn't apply directly.
But macOS apps still pin to MAC, disk serial, and CPU identification — like Windows. Plus Apple-specific stuff: Hardware UUID (visible in About This Mac), Activation Lock token, FindMy ID.
On Boot Camp / Parallels (Windows on Mac), our HWIDChanger works as expected within the Windows partition or VM. We don't touch the macOS layer — only the Windows layer.
If you need an HWID change on a native macOS install, look for niche utilities like "NoNotch" or "OCLP." They operate at a much lower level (boot.efi patching) and require advanced macOS skills.
