Hi,

Not for Mac OS. If you're running Microsoft Windows on your Mac (either through virtualization or through a multi-boot setup), you should be fine, though. Check out this:

(This is for the desktop software products. For the online services it doesn't really matter, since they're pretty much platform-independent anyway.)

I hope this helps!
