TPM | Apple Wiki - Fandom

This article may require cleanup to meet this Wiki's standards. (Need sources to verify whether some of the following in Power Macs is true.)Please improve this article if you can.

A Trusted Platform Module (TPM) is a cryptoprocessing unit that handles security operations such as encryption and decryption in hardware to reduce the likelihood of tampering or a cyberattack.

Usage in Power Macs[]

Early TPMs were used by Apple in PowerPC-based Power Mac G4 and G5 models to allow Mac OS X to load securely on official hardware.[1] Apple used this for its digital rights management (DRM) and Mac OS X licensing as it is soldered onto the motherboard to be registered to that particular machine.[citation needed] The Hackintosh community is critical of this technology as it is closed for the sake of security, and seeks to circumvent these measures to run Mac OS X or macOS on unsupported hardware.

Usage in Window PCs[]

These modules were adopted by PC hardware developers, such as Dell, Intel, HP, and AMD for platform security, and became a requirement for running recent versions of Microsoft Windows.[2]

• Windows 10 requires TPM 1.2 or later
• Windows 11 requires TPM 2.0 or later

In December 2024, Microsoft relaxed TPM requirements for Windows, while maintaining that it was still recommended for security.[3]
