The MacBook Air and the Mac mini line (as well as the newest MacBook Pro) do not include a built-in optical drive. The SecuROM copy protection will attempt to detect the game DVD on launch, and unless you are using a directly-attached optical drive (ie. not using Remote Disc) the detection will fail. In my case this renders the games unplayable on my 2011 Mac mini. The hardware requirements for this compilation do not mention a directly-attached optical drive.
