macOS Monterey: "This app will not work with future versions of macOS"

Is it sandboxed ? Ar at least notarised ?

Thank you for your response. The application is not sandboxed, because it would break some of the features. But it is notarised, yes. In the console, I can see messages regarding the verification of the notarisation, there is no issue on that side.

If an app uses Python 2.7, macOS now triggers an alert indicating that the developer must update the app to ensure it will work in future versions of macOS. (80221011)

Your app may be getting that error because it's using a deprecated version of Python.

• IntelliJ was also getting the same error: https://youtrack.jetbrains.com/issue/IDEA-216133
• CodeWeaver's CrossOver was (or is?) dealing with the same issue.

For the curious, here's how the prompt looks:

@bSr43 Did you file a bug report or contact Apple support directly ?

@Claude31 Not yet, but this is what I've planned to do if I'm unable to sort it out with my next attempt (i.e. replacing usages of WebKit)

Hi @bSr43, this issue is now more than a warning on macOS 12.3 -- it won't even start because of the Python linking

I have ran into this issue myself today and what i found out is that Apple removed the python(2.7) framework(previously found in /System/Library/Frameworks/Python.framework), this is why you get the error. What I did and worked for me was to install python 2.7 from the official python website. This will install as a normal application and afterwords you will get the framework in /Library/Frameworks/Python.Framework .

This worked for me, hopefully for you guys as well

Hi Tommie18

how did you get the framework in /Library/Frameworks/Python.Framework? i reinstalled python 2.7 from official python website and i do not have a folder /Library/Frameworks/Python.Framework
