Starting November 10, 2025, the default resource class for macOS jobs for Free plan organizations will change from macos.m1.medium.gen1 to m4pro.medium. This means that all macOS jobs for Free plan organizations will run on m4pro.medium, regardless of the resource class specified in your configuration. The m4pro.medium resource class offers significantly better performance and faster build times compared to previously available resources.
Note: This change only affects customers on a Free plan. For customers on Performance or Scale plans, the default resource class change will happen on December 3, 2025, as announced here.
What you should do:
- If you are on a free plan and don’t specify a resource class in your configuration, no action is needed - your jobs will automatically use
m4pro.medium. - If your macOS job configuration explicitly specifies a resource class, we recommend either updating it to
m4pro.mediumor removing the resource class specification from your configuration. This is important because when M1 and M2 resource classes reach end of life on February 16, 2026 (see deprecation notice), configurations that explicitly reference these deprecated resource classes will fail to parse. - Note that
m4pro.mediumis priced at 200 credits/min compared to 150 credits/min for the previous default, though faster execution times may offset the higher per-minute rate
