I worked a number of years as a full time Macintosh programmer for Rorke Data Europe based in Emmen the Netherlands
So I just had to get a mac, i now own a PowerMac G4/500 Mhz with 1Gig of ram a 27GB HD, DVD-RAM and a 500Mhz 2001 iBook.
I haven't written much original software for Mac yet, but I ported my Crystal library to OS9 and OSX .. so my source tree now compiles and runs on Mac.
Some of the standard Crystal test application and the Inga game engine.
