We've created a Linux Wine port of the game. Given this is an old title and we cannot change the executable, there are a few issues\limitations:
1) Steam overlay doesn't work for some users
2) The game runs only in 640x480 resolution using Software Renderer
3) Alt+Tab might produce undesired behaviours for example, freezes the game
4) When launching, in the main menu, the mouse can go outside the game's window (it's like the game is running in window-mode) and can navigate through the desktop. When start moving between the menu options, the issue disappears
The game was tested on Ubuntu 15.10, SteamOS and Arch Linux. If you encounter any problems (different that those mentioned above) please attach the log file - G17.log.tx (located in game folder) - as well as a short description. Thank you!
The Mac OSX version is also updated and should run with el Capitan now. On some systems with Intel graphic chipsets the screen appears too bright. In this case, please set the gamma value down in the Graphic Options menu.
