(I bcc'd Alan; apologies if the intrusion is unwelcome, and thanks again for all the work you have done already.)
Since we have upgraded EMBA to Debian bullseye, the NS port tests
fail. See bug#62210.
Alan Third, who has worked on this in the past, has stopped his
activities. Is there somebody else who cares now?
Since a couple days have passed...
I no longer have a macOS machine (not one where I can reasonably try out OpenStep regularly), but there seem to be a lot of macOS+ns-port users out there, especially on the emacs subreddit. If someone could point to/put together a description of what's involved, I (or someone else) could post to that subreddit and try to recruit someone who's in a good position to help.
Thanks,
~Chad
