Simutrans is back on MacOS!

Roboron did it again! After receiving some feedback from MacOS users (and developers), I solved the remaining problems that prevented the MacOS version of the game from running (on Steam or not). Now, MacOS players can play Simutrans... again!

I want you to know that this was not a very easy thing to do, and unfortunately, it is also not a perfect solution. Since Simutrans' developers resources are limited, we can only target newer versions of MacOS. I let you with the details:

[h2]Details[/h2]

• Simutrans has been compiled and tested on MacOS Big Sur (11.0) - and this is the only version that will be supported, initially.
  
• MacOS Catalina may be also compatible! If it is not, please let us now, we can also provide a Catalina compatible version without much effort, and we should support Catalina for now.
  
• Other MacOS versions (Mojave and older) will not be supported. However, if someone on those versions wants to provide a compatible build for Steam players, please read the pinned post on the development forums.
  
• MacOS Simutrans version is not currently a stable version. This means that you won't be able to play online with Steam users (but you will be able to... play!)
  
• Initial tests show that Simutrans crashes if music is enabled (although it can be just my VM). Just in case, I have forced the "-nomidi" option for everyone, but you can enable music from in-game settings. We will solve this later.
  

That's all. Changes are now live. Since I have only tested the release on my development enviroment, I am not sure if everything will "just work" for everyone. I will be listening to your feedback here or on the Steam forums.

With this we reached the #1 milestone of Steam Roadmap.Welcome back, MacOs users!
