Not tried 2008 on my Mac, but if it’s anything like 2007 is on the PC (which I suspect it is), then junk it and go back a generation!
2007 sucks on a PC compared to 2003, so much stuff you can’t immediately do, lack of compatibility etc. About the only benefit is up to 1 million rows instead of 65366 or whatever it is on 2003, but like you ever need that many (only databases really for which you’d be using Access anyway).
No issues running Office 2004 on my Mac at home, works very much the same as 2003 on a PC just with the familiar Mac interface instead of a PC one.
