Update macOS executor for CircleCI

[MikeMcC399]

What would you like?

Update the circle.yml executor for macOS.

Update to an xcode version chosen from Supported Xcode versions for Apple silicon using a version of macOS >=13.5.

Migrate away from CircleCI macOS execution environment resource class using macos.m1.medium.gen1 before Feb 16, 2026.

Why is this needed?

The CircleCI config uses xcode machine image 14.3.1, with macOS 13.2.1 and resource class macos.m1.medium.gen1

cypress-test-tiny/circle.yml

Lines 9 to 13 in f01f393

	executors:
	mac:
	macos:
	xcode: "14.3.1"
	resource_class: macos.m1.medium.gen1

Depending on the version of Node.js used, a minimum of macOS 13.5 may be needed. This would need a minimum version of xcode 15.0.0:

Node.js	minimum macOS x64	minimum macOS arm64
20	>=10.15	>=11
22	>=11	>=11
24	>=13.5	>=13.5
25	>=13.5	>=13.5

CircleCI announced Deprecation of Mac M1 and M2 resource classes on Oct 15, 2025, with brownouts in Dec 2025 & Jan 2026 and removal on Feb 16, 2026.

@MikeMcC399 did you want to do go ahead and do the work for this or should I handle it?

I wasn't sure of the implications of changes in terms of use of this repo in Cypress' main CI workflows or what billing implications it might have, since I can't see what CircleCI plan Cypress.io uses, so I'd be happier if you could handle it in this instance.

I opened a similar issue in cypress-io/cypress-example-kitchensink#1006 and for that one, when the Nov 10, 2025 milestone for Free plan: Default macOS resource class changes to m4pro.medium on November 10 has gone by, I would submit a PR in the kitchensink repo, where I'm more involved in any case.
