Just to clear something up that some people might be thinking about, Apple has had a TPM for years, it’s called the Secure Enclave. It’s just not compatible with the TPM  used by AMD and Intel, and Apple will never open it up for third party use.

but this development shows that the TPM, as used by AMD and Intel, at least, can easily be worked around by software, so its value is questionable.

On Intel or AMD motherboards, during booting, the UEFI part of the boot process checks for the TPM compatibility (if present and which level). TPM can be either a separate hardware chip, or is included in the latest Intel or AMD processors (but needs to be enabled in the BIOS/UEFI settings). On Intel Macbooks with the T2 chip (=where the Secure Enclave is among other functions like the Touchbar, signal processing, audio and certain codecs), Apple could define a TPM 2.0 compatible interface that is reported in the UEFI while booting and can be used in Operating Systems that rely on TPM (more than Windows). Or Apple could enable the virtual TPM in the Intel chips. Both could work. Years later, they still haven’t enabled any of both. 

On the M1 there is no UEFI, and the boot process works completely differently, so you need virtualization software that emulates the TPM and offer drivers for video (and DirectX), touchpad, mouse, thunderbolt, USB, etc. 

I find it strange that Parallels keeps supporting Windows 11 on ARM, while Microsoft does not support this use case. Therefore not an option for business. VMWARE does not support Windows 11 on ARM for this reasons.
