Description

The macos-14/macos-15 runner instances have the same hw.uuid which is preventing licensed software from properly activating during our builds.

Regression from macos-13 runners.

Is it regression?

yes from macos-13

Expected behavior

machine hw.uuids should be unique for each ephemeral runner.

Actual behavior

machine hw.uuids are the same for each respective runner os, which causes our licensed software to reject activations and has to be ran one at a time across all our repos.

Repro steps

not easily reproducible, since timing is a factor when activating the software licenses.
