Is this the section where you are specifying the file type? <key>public.filename-extension</key> <array> <string>msug</string> </array> </dict> Does that look correct for a CSV file? Alex

Jens, Or, confessional debugging. You find the problem while explaining how your code ‘works’ to someone else… Sandor

That happens to me too. Or even better, while composing the email I write "could it be something about ____?", then go check on that possibility and find that indeed it was the problem. (A type of

Don’t worry. We all fall into that trap - more often than you might expect. You wouldn’t imagine how many times when I was preparing an email to the list when I reread what I was typing, looked

Not just app store apps, on Catalina and especially Big Sur, all apps. The suggestion is to have the user drag the app to the “Full Disk Access” panel of the Security & Privacy’s Privacy pane.

I got rejected from the App Store for doing that. However, there are lots of apps in the App Store that prompt for access to the root level of a disk using an Open dialog and get approved, so you may

Presumably you could solicit access to the root of the volume once, and thereafter build URLs for the relevant subpaths based on the security-scoped URL returned by the panel. Per
