VMX option to disable use of XSAVE instruction under Big Sur

This post was originally published on this site

I am running Big Sur on “unsupported” hardware – a Mac Pro 5,1. With updated graphics and WiFi/BLE it is actually running without patches,


To avoid KEXTs VMware 12 is using some extended instructions  like XSAVE under Big Sur. Parallels still allows using it with KEXTs and works fine right now.

Is there a VMX parameter to disable this?


monitor.allowLegacyCPU = “true” does not do it.
