The drivers and software used with most Celestron products are (as of Fall 2009) not compatible with Mac operating systems.
Though Celestron provides no support for these workarounds, some people have had success using Mac-based software and utilities to run Windows on Macs.
The Boot Camp utility in Mac OS X allows Windows to run on a Mac and to run Windows software and drivers, too. The virtualization provided by VMware’s Fusion also runs Windows applications on a Mac. A third program to run Windows on Mac OS X is Parallels.
