-# Running Medley Interlisp on a Mac.
-
-Running on MacOS requires an X server, and building on a Mac requires X client libraries. An X-server for x86 can be freely obtained at https://www.xquartz.org/. For the new arm64 MacOS 11, you'll need https://x.org which you can get via MacPorts or Brew.

-### Middle-mouse tweak
-
-if you don't have a 3-button mouse (wheel = middle mouse)
-you can enable FN-left to be middle. Run in a terminal:
-
-```sh
-defaults write org.macosforge.xquartz.X11 enable_fake_buttons -boolean true
-defaults write org.macosforge.xquartz.X11 fake_button2 fn
-defaults write org.macosforge.xquartz.X11 fake_button3 none
-```
-
-To turn the settings back to the original default values do:
-
-```sh
-defaults write org.macosforge.xquartz.X11 enable_fake_buttons -boolean false
-defaults delete org.macosforge.xquartz.X11 fake_button2
-defaults delete org.macosforge.xquartz.X11 fake_button3
-```

 ### Setting up X
 
-Medley Interlisp needs an X-Server to manage its display. Most Linux desktops have one. 
-If you have a high-resolution display, note that much of the graphics was designed for a low-resolution display, so an X-server that does "pixel doublilng" is best. (E.g., Raspberry Pi does pixel doubling on 4K displayes).
-* It also presumes you have a 3-button mouse (the scroll-wheel on some mice act as one with some difficulty.) See [README-mac.md](./README-mac.md) for more info on dealing with that.
