Re: I asume if you run Windows in a VM
Looks like I might have mis-remembered where I did this, or at least I don't find the reference for VirtualBox at the moment, but https://communities.vmware.com/thread/394665 shows cpu id masking in VMware...
I think I ran into this trying to run an older Mac image on a new (non-Mac) machine, required some hacking, but nothing major.
