KOTOR 2: TSL has been released to support Mac and Linux! In addition, they have updated all versions (Mac/Linux/Windows) to include native widescreen support, controller support, and Steam achievements and Workshop support!
Been waiting a long time for all of this. Widescreen was a much needed addition.
The update to the Windows version is only on Steam, and will be downloaded automatically if you already have it.
