Mac Software to run a tattoo and piercing shop

I am looking for a software package for our shop (tattooo and piercing) that does everything from appoitments, to POS, to inverntory, etc... The catch is we are a Mac based shop and thats where the problem exists. I have found programs like Tattoo Terminal, Mod Base, ProInk, InkScape, Tattoo Software, DecisionSW and a few more. Some people have been very helpful and I am getting some demos, but they are all for PCs. Trying to make it work some how. Does anyone have any idea who makes a package for Macs? Any help with this will be awesome.

working on a MAC is never a problem!

Filemaker pro should do the trick nicely.
