Mac App Store - paid apps crashing | Dev here looking for testers

Anyone that downloaded app from the mac app store and the app crashed upon launching?

One of the reasons could be the messy configuration of your network.

I have been going down the rabbit hole and found a reason why it might be happening but I need some confirmation before I can confidently tell developer community that the modification is safe.

What's the issue?

- mac app store apps have receipt that contain hash and mac address is used to compute this hash. (incorrect hash -> app will crash).

- long time ago primary ethernet mac address was used (typically en0)

- Airplay2 music streaming on mac mini (wired ethernet) caused en0 to be displaced and en0 returned no mac address

- May 2022 apple updated sample code to obtain mac address

- 2023/2024 problems still continue for unknown reason

I have looked how apple is obtaining the mac address internally and there is a slight variation to the sample code they gave to the developers.

What I need:

Run the app and if you see different results for "Apple Sample Code" vs "Apple Media Services Code Copy" please comment with the report (or DM it to me).

- app is notarized (you can check before running in terminal using spctl -vvvv --assess <drag\_drop\_app\_path>)
