Macs are good for flash, but you can use flash on pc anyhow, I think you should get linus xp or 2000(don't mistake it for ME) for your operating system.
If you found or find in future, a program that only works on mac, then i suggest you look for plugins, patches and a lot of registry files, so you can make it work.
