Oh, I tested it in Word and they worked fine. I just figured if it worked in Word it would work in just about anything.
It would be nice if they came out with newer ones' thought, wouldn't it?
You can use the SIL IPA fonts in OS X just as you could in OS 7, 8 and 9.
www.sil.org will get you going, look for the SILIPA93 fonts and you are good to go. They are free and you have three to choose from.
