GH actions: macos build failing intermitently

[kinow]

Describe the bug

Most times it works, but I've gotten a few PR's where the macos build failed and the JS code didn't appear to be the reason.

/usr/local/bin/npx cypress verify

25l[19:53:56]  Verifying Cypress can run /Users/runner/.cache/Cypress/6.1.0/Cypress.app [started]
[19:54:26]  Verifying Cypress can run /Users/runner/.cache/Cypress/6.1.0/Cypress.app [failed]
25hCypress verification timed out.

This command failed with the following output:

/Users/runner/.cache/Cypress/6.1.0/Cypress.app/Contents/MacOS/Cypress --no-sandbox --smoke-test --ping=747

----------

25h::debug::The process '/usr/local/bin/npx' failed with exit code 1
Error: The process '/usr/local/bin/npx' failed with exit code 1

It happened today for #586 . I did as before, and clicked the "Rerun all jobs" button and the second time it worked 🤷‍♂️

Release version(s) and/or repository branch(es) affected?

master

Steps to reproduce the bug

Trigger a workflow a few times, wait to see if the macos build passes or not.

Expected behavior

Consistent behavior.

May be fixed by upgrading to Yarn2 - #593

@oliver-sanders what if we added experimental: true to matrix branch for macos?

I think that would prevent the build from being marked as failure when the macos job failed? https://ncorti.com/blog/howto-github-actions-build-matrix#shadow-ci-jobs WDYT?

[oliver-sanders]

I guess could just comment it out of the test matrix for now since it's failing so reliably.

[kinow]

Unfortunately the build is failing again today 😞 I've committed to master disabling it again, re-opening this ticket too.
