As of today, November 10, 2025, the default resource class for macOS jobs for Free plan organizations changes from macos.m1.medium.gen1 to m4pro.medium.
All macOS jobs for Free plan organizations are now running on m4pro.medium, regardless of the resource class specified in your configuration.
Quick reminder:
- If you don’t specify a resource class in your configuration, your jobs are already using the faster
m4pro.medium- no action needed. - If your configuration explicitly specifies a different resource class, we recommend updating it to
m4pro.mediumor removing the resource class specification to avoid configuration parsing issues when these resource classes reach end of life on February 16, 2026.
