Aha, so it’s not possible to build a Cog VM on Mac OS 10.7 or later, because John’s Mac support relies on QuickDraw system calls that were removed in 10.7, and Cog’s unixbuild won’t build on the Mac (not exactly sure why, Eliot just says so). Too bad… I’ve always appreciated having Ian’s Quartz-based Mac support to fall back on when John’s stuff misbehaved.
You can run 10.7 or later in a VMWare or Parallels virtual machine, but no earlier non-server releases (because of policy issues, nothing technical). So I guess I need to find and buy a copy of Snow Leopard Server.
