Troed,
When I attempt to start Hatari 2.2 on my MacBook Pro (macOS Mojave 10.14.3, Retina display), it only shows the lower right hand corner of the ST desktop and the indicators were far too large as well. I moved my hatari.cfg file to make sure it was not the result of an invalid configuration file. The same behavior existed in windowed and full-screen mode. I was able to compile my own version of Hatari using the SDL 2.09 framework. That version appears to work successfully. In full screen mode, I did have garbage appear on the left-hand and right-hand sides of the Mac screen outside of the ST desktop area. However, it appeared to disappear after toggling Hatari a couple of times between windowed and full-screen mode.
Since I have a very plain Mac, I am assuming other Mac users (probably with Retina displays) will have problems with this release.
Everyone else,
I was unable to generate an Xcode project using CMake 3.13. I had to downgrade to CMake 3.12 in order to generate the Xcode project. After that, my old compilation instructions worked perfectly. I am assuming there were major changes to CMake in 3.13.
