I can confirm that it works, but somehow I can't bring myself to actually play MP 3 now... just another round of Faster Than Light and then we'll see...
Rockstar support replied today regarding the Mavericks issue:
Thank you for contacting R* Support. We've received several reports of incompatibility issues with Max Payne 3 and OS X Mavericks. We're currently investigating these reports, but don't have any additional information at this time.
Thanks for the info. Hope they fix whatever the problem is. I hate rebooting and haven't gotten around to this game yet. It can keep waiting too. I'm not in a rush.
see on most games that would keep me happy, just fire up bootcamp, download 3 or5 or even 10 gigs and play it....but having just dumped 28 gigs the night before last on the mac version, im hesitant to download another 28 gigs tonight....
