I’m not able to get this working - it keeps running in regular macos.x86.medium.gen2. Any tips?

Maybe you are on the Free plan? Per CircleCI Resource Classes - CircleCI M1 Medium is not available on the Free plan.

Just tried out the M1 medium resource and I’m seeing nearly a 50% decrease in workflow times, which is a great result given the 2x credit cost.

In fact, looking at the runtime of my original jobs, I’m seeing as much as a 3x speed increase on the biggest job - the workflow runtime could still be better but it seems to be spending up to 30-60s sometimes queued waiting for an executor to become available. Is there any chance this could be improved?

We’ve gone from a median workflow time of around 17-8m down to 10 minutes but I think with reduced queue times we could get this down to around 7-8m.


I’m thrilled to hear you’re seeing great performance improvements! As we get more usage, we certainly expect our pre-booting algorithm (and therefore queue times) to improve. Thank you for the feedback!

Hi, I’m unable to receive Push Notifications on the CircleCi simulator. I’m using macos.m1.medium.gen1, xcode: 14.3.1 and iPhone 14 v16.4. I have the same setup locally, same app build and Push Notifications are working. Any ideas? :pray:
