 ## Using pre-built binaries
 
+NOTE: Currently Windows builds are broken. See [#98](https://github.com/haskell/ThreadScope/issues/98) for the current status.

 Currently [pre-built binaries](https://github.com/haskell/ThreadScope/releases) for the following platforms are provided:
 
 * Ubuntu Trusty (64-bit)
-* OS X
+* macOS (XCode 11)
 * Windows (x64)
 
 GTK+2 needs to be installed for those binaries to work.
 
-On OS X, `gtk-mac-integration` also needs to be installed.

+On OS X, [`gtk-mac-integration`](https://github.com/jralls/gtk-mac-integration) also needs to be installed:
+
+```sh
 brew install gtk+ gtk-mac-integration
 ```
 
 On Windows, the [MSYS2](http://www.msys2.org) is the recommended way to install GTK+2. In MSYS2 MINGW64 shell:
-```
+
+```sh
 pacman -S $MINGW_PACKAGE_PREFIX-gtk2
 ```
+
 then you can run the threadscope binary from the shell.
