Running Nokia PC Suite on a Mac is NOT a hassle free thing to do, and is also one of the reasons why Apple should embrace Symbian for its iPhone.
Luckily, people like Mark Guim from the Nokia blog have been thinking about the issue and have come up with the solution. Again, it’s not easy, but it’s well worth it.
Not to rant too much, here’s Mark’s post explaining step by step how to use Nokia PC Suite on a Mac.
UPDATE: There is a Nokia Music Manager for OS X available for Mac users. (thanks to My Your’s & Our E- 70 and E61).
