Update timeline
- identified Nov 26, 2025, 10:53 PM UTC
We are seeing an increase in wait times to start jobs on Mac M1 Large. Customers are encouraged to move workloads to Mac M4 if possible.
- resolved Nov 26, 2025, 11:24 PM UTC
We are in the process of deprecating our M1 fleet due to limited machine capacity. So while all jobs will run, some running on M1 Large may be delayed. Customers may move to M1 Medium if you must have an M1 chip. Otherwise we encourage customers to move to M2 and M4 resource classes. Thank you for patience and we apologize for any inconvenience.
