Portal for MAC.
Known bugs/issues:
After application launch in main menu mouse doest work, change any graphic settings - mouse works, or just load a game. Use directional keys, tab and enter to get to configure dialog(Yeah remember the past times without mouse controller).
Settings are not saved, every time you need to apply them again from begining.Savegames are saved normaly.
Some graphics issues - such a not working HDR(or working with a graphics bug) and very small draw distance, so some objects may disappear from view but exist in game world, just come closer.
Some textures are not rendered correctly.

After launching application you notice that mouse is not working correctly and video settings are not saved. Spent 2 minutes for adjusting settings.
Use directional keys, tab and enter to get to options and change any graphics settings in advanced, apply, after game finishes mouse will work.
You also can load the savegame - in game mouse will work correctly.
Do not turn on HDR it will cause some graphics artefacts.
