Post-build step hangs on self-hosted mac runner

[AArnott]

When running on private runners the cache works except on mac agents, where the cache hangs on the post-build step:

Post job cleanup.

I've given it 30+ minutes to finish but nothing further ever gets logged. When it succeeds (on a github hosted agent) it takes under a minute.

Any ideas?

Could it be that there are a lot of .DS_Store created in the repository/places to be cleaned/cached

[AArnott]

@NobodyXu The self-hosted runner is brand new, with only one repo on it. Given the whole build up to this point took about 10 minutes, it's hard to imagine it could have created anything that would take 30+ minutes to delete. Plus, this attempted to run 3 or so times before I disabled it, each running for at least 25 minutes. So if it was making progress on something that would be cumulative like deleting some location outside the repo, it's had probably 80+ minutes to do it.

Hmmm I'm not sure what caused it either.

Is there a way to increase logging?
