That's interesting, @mcored, It has to be one of two things. I checked the KB articles again and they don't specify it only works on certain Macs. It does say Parallels must be either Parallels Desktop for Mac Pro Edition Parallels Desktop for Mac Business Edition Are you running either of these versions of Parallels? Or - if you go to Hardware > +, but a TPM chip isn't there, it means your Windows virtual machine is based on Legacy BIOS. TPM chip will work with UEFI/EFI BIOS only. If Legacy is set, create a new Windows virtual machine. When you get to the Name and Location window when creating a machine, enable Customize settings before installation. In the automatically opened configuration window go to Hardware, click + > select TPM chip > Add. Close the configuration window and proceed with Windows installation.
