I never followed-up, but for devs, https://travis-ci.org/pantsbuild-osx/pants/ has been green now fairly solid. There was one failed CI due to a timed out shard, but it seems like a hardware failure sort of thing, the timeout was a few deviations away from norm. So ... keep keeping an eye out on https://travis-ci.org/pantsbuild-osx/pants/ and soon enough @bored-art-40741's work on the mac-mini1 node on jenkins will be part of the mainline CI.
