Mac users can use My Class Reunion.exe by installing a VPC (virtual PC). There are many choices so use your search engine for a subject like 'Mac to PC VPC'.
A VPC is a separate partition and the only common element is the host Mac Operating system (OS). The two partitions share nothing. Therefore, in order to use any of the reporting functions a printer must be installed on the VPC partition just as it was installed on the Mac OS. An additional item is Adobe Acrobat reader. Go to Adobe.com and download the latest version of the free reader.
Each report can print to multiple formats including pdf, word doc, RTF (rich text format), text files and html. The files can then be sent via eMail. However, in order to print the file from the VPC partition, a printer is needed.
If you have any questions about either VPC's or the OS, please let me know.
