Hi I noticed this when building apache-arrow that Homebrew released a new patch version
... ==> Upgrading apache-arrow 7.0.0_3 -> 7.0.0_4 ... And now it works! I tried to see what has changed and found this which sounds related: https://github.com/Homebrew/homebrew-core/commit/0d53c4ddc79abc153967d0f903c5621eab59e422 However, that change should already have been included in 7.0.0_3, so I'm confused... In any case it seems this was a Homebrew issue and that it is now fixed. I appreciate all your help, and I learned a lot about macOS along the way. Thanks /Sten
