Mass calibration freezes on macOS

[trappitsch]

Describe the bug
Mass calibration window freezes when hitting the apply button and nothing seems to happen when using executable on macOS.

To Reproduce
Steps to reproduce the behavior:

1. Open a file
2. Start a mass calibration
3. When done, hit "apply"
4. Program freezes

Problematic file
The Ti test spectrum in the tests will result in this issue, at least when the json calibration file is not present.

Package:

• rimseval v2.0.1
• Executable downloaded from RIMSEvalGUI v2.0.12

Desktop / GUI (please complete the following information):

• OS: macOS, latest
• M1 chip,
• Arguments stripped as described in documentation

Additional context
Unclear at this point if this happens in the non-executable version as well. Need to debug on a mach in order to find where the issue comes from. Freezing the software with fbs on the GitHub runner does not throw any errors:

Run fbs freeze
  fbs freeze
  fbs installer
  shell: /bin/bash -e {0}
  env:
    pythonLocation: /Users/runner/hostedtoolcache/Python/3.9.13/x64
Done. You can now run
`target/RIMSEvaluation.app/Contents/MacOS/RIMSEvaluation`. If that
doesn't work, see https://build-system.fman.io/troubleshooting.

Unclear why this is the case, really hard to debug without a Mac. The whole M1+ chips made this even more cumbersome. Trying to solve this with a Docker alternative version, see here for more detail. Please report back if this works.
