Apple OS onboarding doc

[richlander]

Is there a doc that describes how to onboard a new Apple OS (for build or test) in this repo?

We've started writing such docs to make ourselves more efficient and make such tasks more easily repeatable.

Here are some other efforts:

• Add doc on OS onboarding runtime#112026
• Create an OS onboarding doc aspnetcore#60281
• Source build and VMR should move to CentOS Stream 10 and Alma Linux 10 in main source-build#4890
• Android OS onboarding doc runtime#113443

We don't have such a document at the moment, but I agree it's a good idea to create one, since updating to a new Apple OS is the major undertaking for pretty much the entire team every summer.

It would probably be easiest to create such a document this summer, when we update to the next OS version, so scheduling it for then.

Sounds great and yes I agree that documenting something like this "in the moment" is the best plan.
