Granted I am unsure how well it will work under a Mac, I know OSX has had a lot of under the hood changes with certain compatibility.
I mean it still has CUPS (the common unix printing system as OSX is loosely based on Unix) so you could try something there, not sure if it will make the whole unit work though as cups mainly is for printers not scanners.
Worse comes to worst you may need a new printer/scanner, sucks i know as if its worked for this long it will suck to give it up but sometimes compatibility is something that can be an issue on a non windows system.
For as much clout apple gets they still dont have as much hardware support as windows does, heck I even think linux has better hardware support these days (but thats thanks to open drivers something that apple really lacks on)
