 ### macOS
 
-Similar to Linux build, but need `macdeployqt ./goldendict.app` to copy necessary dependencies to the app bundle.
+If you build in an IDE, then the created `goldendict-ng.app`  will be runnable from the IDE which set up necessary magics for you.
+
+To make the `.app` runnable elsewhere, you can run `cmake --install build_dir/` which will invoke macdeployqt, ad-hoc code signing and various other things. The produced app will end up in `build_dir/redist/goldendict-ng.app`
+
+To create `.dmg` installer, you have to have [create-dmg](https://github.com/create-dmg/create-dmg) installed on your machine, then also `cmake --install build_dir/`.
