should this match the oldest os specified on line 52?

[codeboten]

follow up question do we need to specify intel here?

[v1v]

Good questions, a bit of context:

The macos-13 is intel based, while macos-14 and macos-15 are arm-based, so the only way to keep the same arch was by using the macos-15-intel runner.

[codeboten]

I think its fine if we test on arm, based on the platforms we support, arm64 is a higher priority than arm64 https://github.com/open-telemetry/opentelemetry-collector/blob/main/docs/platform-support.md#tier-2--secondary-support

[v1v]

I applied your suggestion:
