Re: .exe files on mac
u could try a program called vmware. Don't know if it's available for macs and don't know exactly how it works, but it creates a virtual OS and u can use both of the OSs at the same time.
also, at least with linux u have programs like wine which let u use windows based programs on linux. Don't know if there is anything similar with macs, but u could try and find one if u have the time to spend.
