Hi. Does anyone know which macOS versions are supported by Git?

I don't think we have any formal decision here (or for any other
platform; it is usually a cost/benefit for individual features we may
want to depend on).

Motivation: I spotted that git-credential-osxkeychain.c uses a
deprecated API. SecKeychainAddInternetPassword was deprecated in
2014's macOS 10.10 [1].  Replacement SecItemAdd was introduced in
2009's macOS 10.6 [2].

+cc Taylor, who I know was looking into this recently.

I'd guess that anything older than 2009 is probably not worth worrying
about.

Further motivation: If I understand the documentation correctly, the
new SecItemAdd API has better support for storing attributes alongside
secrets, which might be handy for storing Git credential's new
password_expiry_utc attribute (d208bfd, credential: new attribute
password_expiry_utc, 2023-02-18).

Yeah, that would be a nice bonus (in addition to avoiding a deprecated
interface).

I had similar issues last year with older versions of the compiler
tools and/or an API that I was using in FSMonitor.

IIRC my API usage needs 10.6 or newer.
