Unit tests fail on macOS

[valgur]

While macOS is not explicitly supported, it should still run without any issues on ARM64 if the code has been constructed correctly. An AppleClang build in the CI (https://github.com/valgur/novatel_edie/actions/runs/9731990895/job/26857109732) currently fails in 4 unit tests (or 2 distinct ones, really):
