 However, as far as I know there's no guarantee that NSImage will keep treating true-color images the same way in future macOS versions, meaning this workaround could break eventually - and it doesn't do anything for custom images installed in `${XDG_DATA_HOME:-$HOME/.local/share}/lix`.
 
-Therefore, I also have an alternative workaround implemented. If you set `convertImagesToTrueColor` to `false`, Lix will instead be linked against a custom build of Allegro 5 which has the macOS native image loader disabled, and instead uses the same `libpng`-based method as on Linux and Windows, avoiding the bug. To prevent this as well (for instance, to test out the bug's behavior on a given version of macOS), additionally set `disableNativeImageLoader` to `false`.
