+### Installing on macOS
+
+Engine Core can be installed on macOS as well, but with some restrictions:
+
+- Intel-Macs only (related to liquidsoap version 2.1.x; will be obsolete when we're upgrading to 2.2.x. __NB: Don't try to upgrade to 2.2 - this won't work without refactoring the implementation__)
+- instead of `apt`, use a package manager for macOS, such as `homebrew`
+- install without ALSA-libraries (which will fail since macOS uses CoreAudio instead of ALSA)
+
+Your installation procedure might look something like this:
+```bash
+brew install opam
+opam depext pulseaudio bjack ffmpeg samplerate flac taglib mad lame vorbis flac opus cry ocurl liquidsoap -y
+opam install pulseaudio bjack ffmpeg samplerate flac taglib mad lame vorbis flac opus cry ocurl liquidsoap -y
+```
+
+Please note that `make.init.dev` also uses `apt` for installing additional packages, so in the makefile, you need to replace `apt` with `<your_package_manager>`, such as `brew`.
