GTK apps feel pretty clunky under macOS, with GIMP feeling moreso than other GTK apps with its various oddball UI patterns that don't even fit in with a GTK Linux desktop (like its layer palette with what looks like a standard list view but behaves nothing like a standard list view). It also doesn't handle multiple monitors well (alerts popping up on a different screen than the document window is on). In summary, it's pretty unpolished option among image editors that run on macOS. Also, GIMP isn't the most lightweight of software out there… it can be overkill depending on needs.
