OS X might but don't count on it. the wings card in OS X is basically the same as having the whisper card cause of lack of drivers ot support it, and the AIO's monitor connects to the personality card to get its signal. so many functions do not work in OS X on the Beige G3. you will have to use OS 9 with the display adjusting utility (DAU) http://home.wanadoo.nl/manual.man/dau4_2.sit.bin or display service utility (DSU) ftp://grijan.cjb.net:21000/macintosh/Manuals/displayservutil.sea.bin
even if the Beige G3 was supported in jag, you could really call it semi support. cause not much was supported.
