http://forum.microchip.com/tm.aspx?m=304173 Robert Welch (from Microchip) has reported the following. "I've got one of the older Macbook Pros using the Intel Processor. Since the release prior to V3.0, Parallels has allowed me to use ALL USB development tools while running XP Home Edition, updated to SP2. I've used: Real ICE, ICD2, Pickit1, Pickit2, ICD2 LE, PM3, and the ICE4000." So Mac users (normally are willing to pay more to think different: Parallel Desktop and Windows XP SP2 are not that expensive anyway compared to a new Mac) should have a good solution now.
