4. My Macintosh computer is having various problems with SigmaChat.
SigmaChat is not supported on Macintosh OS 8.x and below systems. SigmaChat runs best on OS X when using MSIE, Netscape or Mozilla. When using OS 9 we recommend using MSIE only. Problems have been reported when using the Safari browser.
