Description

I am writing a cross platform MAUI app to run on Windows and MacOS. It tries to access an external flash drive. Everything works fine on Windows.

When I try to run the app on MacOS I get this exception:

Access to the path '.....' is denied.

Where ..... is the path to my external drive and file I am trying to open.

I never get any kind of permissions dialog like I would expect.

How do I make this work on MacOS?

Steps to Reproduce

1. Create MAUI app
2. Run the app on MacOS
3. Try to open a file on an external drive for Read/Write
4. Get error that access is denied.

Did you find any workaround?

No
