 The two folders within the `res` folder (`res/res` and `res/css`) are necessary. Windows also uses the `fonts` folder.
 You can put them directly next to the executable. On Linux, `css` and `res` can also be loaded from
-`~/.local/share/abaddon` or `/usr/share/abaddon`
+`~/.local/share/abaddon` or `/usr/share/abaddon`. On macOS, when installed via package managers
+such as Homebrew, the install prefix (e.g. `/usr/local/share/abaddon` or the Homebrew Cellar location)
+is also checked for resources.
 
 `abaddon.ini` will also be automatically used if located at `~/.config/abaddon/abaddon.ini` and there is
 no `abaddon.ini` in the working directory
