note we may need for 1.2.5 as well?

will know for sure when I do the manual backport of #41924

or could backport anyway?

@jorisvandenbossche Do we want to bump min version to 0.17.1 in general for MacOS, not just in the CI?
@simonjayhawkins I think 1.2.5 is still on pyarrow 0.15 so shouldn't backport?
EDIT: See below comment for clarification.

we don't really want ci constantly failing. if we need a patch for pandas 1.2.x to work with pyarrow 0.15 that's a different issue.

Sorry, should've been more clear.
The MacOS Python 3.7 job on Azure is on pyarrow 0.15.1 on 1.2.x.

pandas/ci/deps/azure-macos-37.yaml

Line 24 in 322d54a

- pyarrow=0.15.1

According to the JIRA issue, it seems this would only affect 0.17.0. I guess we should just first not backport, and then backport if CI is red on the MacOS job then.
