Melissa,
PTC has just started to support Mac OS X clients at Windchill
10.1. There are still a few missing pieces though, like Creo
View and desktop integration.
But based on the viewing capabilities in the Windchill mobile
app, which runs on iOS I would imagine that some sort of Creo
View capability for Macs may be in the cards at some point.
But that is of course purely speculation on my part. Or
perhaps a bit of wishful thinking 🙂
I have been using a Mac for Windchill development for several
years. Completely unsupported of course. While there are some
shortcomings, there are also some advantages...
