A couple of readers have asked about Torchlight 2's much-delayed Mac port, so we reached out to developer Runic to see what's up. Here's their statement.
The official word as of right now is that we encountered unexpected complexities in porting Torchlight 2 to the Mac, simultaneous with our scramble to ramp up on our next project and get it moving forward. The Mac platform still poses some challenges for us as a company (as anyone who waited for the Mac port of Torchlight 1 can attest). As a result, while we are still pursuing it, we don't have a date or any real details to share on the Mac port of Torchlight 2 just yet. When we do have something to share, though, we'll do so as quickly as possible.
