Ghost Recon on Mac OS X 10.7 (Lion) and later
As this comes up more and more often now, I figured it might be worth a separate topic. Mac OS X 10.7 (Lion) and later versions do not support running legacy applications like Ghost Recon anymore. A simple solution to play GR on modern Macs is to use the PC version of the game inside a Wineskin Winery wrapper that acts as a normal Mac app and provides full compatibility with the PC version of Ghost Recon (including expansions, mods, online/LAN multiplayer etc.).
I've prepared an empty wrapper that is fully SP/MP compatible and even allows all intro/outro video to be played. Just download, expand the archive, double-click the app and install GR either from its original setup.exe or by just copying the "Red Storm Entertainment" folder from a PC to the "Program Files" folder on the virtual C: drive inside the wrapper.
It's basically the same for installing a mod. For manual (drag and drop) installation, right-click the wrapper, select "Show Package Contents", navigate to "drive c:/Program Files/Red Storm Entertainment/Ghost Recon/Mods", drop the mod into this folder and activate it in the game's options menu. Alternatively, you can use a mod's installer executable (.exe). Right-click the wrapper, select "Show Package Contents", double-click the Wineskin icon, and click the "Install Software" button.
In conclusion, this is really neat - the Wineskin wrapper allows to install the PC version of Ghost Recon (including expansions and mods for PC) on any modern Mac, fully cross-platform compatible with feature parity! The performance is absolutely on par with the native version too, i.e. I see no performance degradation when using the wrapper on my Mac compared to a native GR install on my PC.
A cool little side-effect of this wrapper is that all Ghost Recon mods for PC are suddenly fully Mac compatible!
Enjoy Ghost Recon (and mods) for PC on Mac!
