## What changed

**1. Added: Update** (monitoring) · 2026-10-20 17:31 UTC

```diff
+ Wait times for macOS jobs on the m4pro.large resource class are recovering. Jobs using Xcode 27.0 are now waiting about ~3.5 minutes on average, down from about ~40 minutes at the peak. Jobs using Xcode 26.6 and 26.4.1 are still working through a backlog, which is clearing. Wait times on m4pro.medium are normal. We will share another update soon as we continue to monitor.
