- Please put the system name in the title of this issue.

- Link to any log file showing the problem: https://ci.adoptopenjdk.net/label/ci.role.perf&&sw.os.osx&&hw.arch.x86/

- Please describe the issue: While we are [not yet utilising](https://github.com/adoptium/aqa-tests/issues/2401) the `ci.role.perf` in order to direct the `perf` tests onto specific machines for consistency, both of the current systems with the above label are currently offline.

Start with the CI label page for ci.role.perf&&sw.os.osx&&hw.arch.x86 and review the linked AQA issue for context. Identify the two offline systems, determine why they are unavailable, and update the issue title with the system name; done means the systems are back online or their maintenance status is documented.
