The developers of Darktable, an open source photo editing alternative to Adobe Lightroom will likely have to end MacOS support after the next major release 4.2.1.
For the last 10 years, a single person has been responsible for maintaining and packaging Darktable for MacOS. Unfortunately, that tenure is coming to an end for the developer as they move onto other things in life.
From Darktable Lead
At the same time, there is a big roadblock on the OS X side:
currently, as requested by @parafin, the minimal required
XCode version is XCode 12.4 (LLVM10-based),
and with LLVM16 about to be released in ~April,
that puts us to 7 (sic) LLVM versions to support,
in addition to currently supporting three GCC releases.
Not only is this support matrix unsustainable,
not having a path forward makes it impossible
to someday make use of the compiler (and library)
features introduced in later compiler versions.
In summary, unless someone steps forwards and commits
to the role of OSX maintainer, we will be forced to
fully and completely stop supporting OS X,
after the next minor release (4.2.1).
If you are interested to help, please step forward.https://discuss.pixls.us/t/darktable-for-macos-needs-you/35142
We really need a long term dedication to solve this.
An Open Source software can only offer what
the community can work on.
