Add support for macOS hosts

[dgsga]

Netatalk does run on modern Intel and Apple Silicon based Macs with a number of code patches which have been tested over a two-year period.

As a side note, I think this would warrant a minor version bump, since it introduces a major new capability: netatalk 3.2.0

[slowfranklin]

Out of curiousity: why? Why running Netatalk on OS X when the builtin AFP server is cleanly integrated with the OS, avoid the crutch of AppleDouble sidecar blob and the like.

[rdmark]

Didn't Apple get rid of the AFP server ages ago, and only kept the AFP client alive in macOS?

[rdmark]

The AFP server deprecated with Big Sur, according to MacWorld: https://www.macworld.com/article/234926/using-afp-to-share-a-mac-drive-its-time-to-change.html

[slowfranklin]

I kinda lost track when it AFP was deprecated in favor of SMB, quite a long time ago already apparently, and if the AFP server was ever actually removed, was it?

[rdmark]

It's a good question; did Apple decisively remove the AFP server code, or is it still around and accessible through CLI shenanigans?

The official macOS docs do mention AFP file sharing as an option for Big Sur, but not Monterey or Ventura. So this confirms the official story.

Just checked, the Apple AFP server binary (afp) is definitely absent from Ventura. Quite relieved really as it might have made all my work on the macOS port null and void!

:) Did you add a Mac specific metadata backend that stores all the Mac metadata natively in the filesystem or is it just build fixes so the metadata will be stored in AppleDouble sidecar files or xattrs?

[dgsga]

Just a minimal alteration to the ea search macro allows metadata to be stored in the native APFS filesytem.I don't have the programming knowledge to build a backend...

[dgsga]

Nearly there, just have to sort out an authentication issue...

[rdmark]

The code in in main now. Great job!
