These instructions for macOS asssume that the Xcode command-line developer tools are installed (if Xcode is installed, open the Terminal, type “sudo xcode-select –install” and accept the conditions).
It is also assumed that CMake >= 3.13 is installed: this can be done with package managers MacPorts, Fink or Homebrew, or by a download from https://cmake.org/download/.
First get the latest macOS release of GStreamer-1.0 from https://gstreamer.freedesktop.org/download/. Install both the macOS runtime and development installer packages. Assuming that the latest release is 1.20.1. install gstreamer-1.0-1.20.1-universal.pkg and gstreamer-1.0-devel-1.20.1-universal.pkg. (If you have an Intel-architecture Mac, and have problems with the “universal” packages, you can also use gstreamer-1.0-1.18.6-x86_64.pkg and gstreamer-1.0-devel-1.18.6-x86_64.pkg.) Click on them to install (they install to /Library/FrameWorks/GStreamer.framework). It is recommended you use GStreamer.framework rather than install Gstreamer with Homebrew or MacPorts (see later).
Next install OpenSSL and libplist: these can be built from source (see above), in which case you may need to install the standard development tools auutoconf, automake, libtool, which can be done with MacPorts, HomeBrew, or Fink. Only the static forms of the two libraries will used for the macOS build, so you can uninstall them (“sudo make uninstall”) after you have built UxPlay. It may be easier to get them using MacPorts “sudo port install openssl libplist-devel” or Homebrew “brew install openssl libplist” (but not Fink). if you don’t have MacPorts or Homebrew installed, you can just install one of them before building uxplay, and uninstall afterwards if it is not wanted.

Finally, build and install uxplay (without ZOOMFIX): open a terminal and change into the UxPlay source directory (“UxPlay-master” for zipfile downloads, “UxPlay” for “git clone” downloads) and build/install with “cmake . ; make ; sudo make install” (same as for Linux).
On macOS with this installation of GStreamer, the only videosinks available seem to be glimagesink (default choice made by autovideosink) and osxvideosink. (It seems that vaapisink is not supported on macOS). The window title does not show the Airplay server name, but the window is visible to screen-sharing apps (e.g., Zoom). The only available audiosink seems to be osxaudiosink.
