Trying to find documentation for Appium for MacOS apps and not iOS apps on Mac system.

When I needed to automate an OS X app I evaluated this, but it did not work very well at the time (2-3 years ago). I settled on just automating with AppleScript, which while somewhat painful, we found to be both fast and reliable. YMMV.
