…or Ryzen 2000.

So basically any computer more than four years old is out of luck… and a lot of newer PCs are going to be out of luck too. Much worse support than macOS 12. Seems very arbitrary since Coffee Lake is essentially the same as Kaby Lake and Skylake. (Hardware protection against Spectre etc wasn’t introduced until 9th-gen Coffee Lake-S.)
Surprised this isn’t getting more attention, it seems like a much bigger deal than the TPM thing. Gotta think that Microsoft is eventually going to compromise on this one.
