As soon as Outpost 2 v1.3.6 is released, I'll be pushing out the 1.2.0 macOS release. I've been working on a (basic, as I'm not a serious programmer) game launcher to go along with it to give access to the game settings file, as well as to provide an "Online Support" option to link the user back to either OPU or NTCS (both are currently included as options). Eventually, I plan on adding an Update Game option. Right now that button opens a browser page for the macOS download and reports the currently running version.
I'll also be adding a link to the Help Manual section of the OPU Wiki, as macOS doesn't use the same type of offline help manuals, and I see little need for an offline file in this particular environment.
If anyone has any thoughts or suggestions, feel free to let me know.
