Hi,

I’m receiving the below error message while running a dmg app created via Application Compiler.

I’m using macOS Monterey (v12). I checked all Security & Privacy configurations and enabled every possible option. The interesting thing is that when I run the m file inside Matlab, it generates the outputs successfully. Any ideas on how to handle this issue?

Thanks in advance,

Mel

I see this claim, but I do not know if it is accurate:

The instructions at https://www.techwalla.com/articles/how-to-edit-dmg are more along the lines of what I have read in the past.

Thank you very much @Walter Roberson. It turns out that dmg files compiled by Application Compiler cannot write to relative file paths. Changing relative paths into absolute ones solved my problem!

E.g.

Changing this:

writetable(data, 'file.xlsx')

into this:

writetable(data, fullfile(path, 'file.xlsx'))

Cheers,

Mel

That would hint that your current directory is not what you expect

As a matter of fact, it is. Because as I mentioned in my first message, the same m.file (that the dmg application is compiled) generates outputs successfully through Matlab Command Window in the same computer. However, the permission is somehow not granted when the same request is sent from the dmg application.
