We have heard from him and he is quite active, but not so much on the IRC
channel, which may be why you get this impression. 🙂
Actually he just released a revision 3 of the DMG (like barely 2 days ago
and it was uploaded on download servers yesterday but not on the website
yet as we need to wait for mirrors to pick it up). I suggest to anyone with
issues to test it (gimp-2.10.22-x86_64-3.dmg):
https://download.gimp.org/mirror/pub/gimp/v2.10/macos/

For the record, from feedbacks so far, the revision 2 DMG was already much
better on Big Sur, but it turned out it was slower for macOS before Big Sur
(for this, the revision 1 was better). Our new macOS contributor thinks
that this last revision should be better for everyone. We welcome feedbacks
to confirm (or oppositely to refute).

Indeed as a general rule, GIMP is fully community-developed and relies on
volunteers (whichever the platform even).

And more particularly macOS has always been the platform with lowest
contributors (even since I started to contribute, this is the only platform
where we never managed to get more than 1 active and regular contributor in
the same time as I recall).
So we really encourage people who like GIMP on macOS to actually
participate. This is the only way for support to be actually reliable.
