Xorg is still widely used in Linux distros far and wide.)īut Wineskin, distilled from Wine, which in turn is native Linux software, uses X11 to create the application window on Mac, and so refuses to start the game altogether when that app is missing, printing an error and prompting to quit. Linux, too, is making a transition to other window managing systems, but painfully slowly. (Note: rightly so, because it is an ancient piece of software.

This program was shipped with Mac, too, up until 2016 or earlier, but Apple stopped shipping the software with macOS operating system and discontinued the X11.app altogether. Wineskin isn't actually the problem at hand, but more precisely, it uses a Linux standard window manager called x.org or X11. Considering that both macOS and Linux share mutual roots on the ancient UNIX operating system, it's no wonder that Wine can be ported to Mac fairly easily. It is a program that translates original Windows software on-the-run so they can be executed on Linux. Wineskin is distilled from a program called Wine (pun intended). But it's wrapped into a compatibility container called Wineskin on Mac, which directs to the problem in hand. First and foremost, it isn't a native Mac app to begin with - it actually is the same Windows version that ships to, well, Windows. The X11 error stems from multiple layers of compatibility built into the macOS version of the game. I didn't find a solution posted for the infamous "The application X11 could not be opened" problem on newer macOS (OS X) operating systems.
