@janne@social.treehouse.systems @nicolas17@social.treehouse.systems you can get that from the macOS IPSW BuildManifest. It's 0x6050. Apple stopped the "ChipID is unique across SoCs" with A18/A18 Pro. :/

@siguza@infosec.space @janne@social.treehouse.systems I think M5 Pro and M5 Max use the same CPU die attached to a different GPU die, so that could explain why the CPID is the same. But on the other hand, M1 Ultra is two bonded M1 Max and yet those have different CPIDs. And A18/A18 Pro having same CPID has no sensible defense...
