Update: May 4th
We’re passed May 1st and the Bintray shutdown. As we know, CircleCI’s macOS images contain an older version of Homebrew, which is affected by the Bintray shutdown. We’re addressing the issue in two ways.
A Patch
To address the situation immediately, a temporary fix to automatically update Homebrew has been put in place for existing macOS images to prevent failed pipelines due to this issue. Some users, depending on the age of the image, may notice slower startup times. This is temporary as we continue to roll out the permanent fix.
Permanent Fix
The macOS Team is working diligently to get our entire macOS fleet updated, prioritizing by image usage. These will ship updated versions of Homebrew.
