Trusted Platform Module.

i do some contracting work with an organisation that requires that my computer has a Trusted Platform Module. How do I know if my Macbook air has this? And my iphone?

TPM is a feature required by Windows 11 and by some add-ons.

TPM is implemented either directly in hardware or emulated by a hypervisor.

Mac does not have a TPM, nor does iPad or iPhone.

Mac uses different hardware for related purposes; either the secure enclave in Apple silicon, or the T2 secure enclave in Intel Macs.

Both TPM and T2 have had security flaws.

Overview (written before the discovery of T2 flaws):

As far as I know, a TPM module is only required by the Windows 11 operating system on the PC platform. Your MacBook Air & iPhone are not affected by this as they run macOS and iOS respectively.

Try a Google search for "TPM module". You find a ton of info out there.
