Mach 3 and mac computer

I have an older mac and Ive seen a couple threads saying you can run Mach 3 on a Mac and something about Parallels. Just curious if there is a number to call an email to see or a link to download the mach 3 software on a mac.

I don’t use a Mac for much but I have a MacAir that I use Basecamp on and run Mach3 in Windows on - that’s what I use for my Crossfire laptop. I figure it’s a little more resistant to water spray than a non-solidstate machine.
