Subject: [PATCH]: Update privacy usage descriptions for macOS 10.15 Catalina
 (nextstep)
Date: Sun, 29 Sep 2019 11:21:05 +0100

Hello there,

Apple has updated requirements related to privacy on macOS Catalina. Now we have to specify usage descriptions for the following items to be able to access these folders and volumes:

- NSDesktopFolderUsageDescription;
- NSDocumentsFolderUsageDescription;
- NSDownloadsFolderUsageDescription;
- NSRemovableVolumesUsageDescription.

(https://developer.apple.com/documentation/bundleresources/information_property_list/)

Otherwise, it is impossible to work with files in these folders (especially, when Desktop and Documents are synchronised with iCloud). Full Disk Access permission does not help in this case. The only workaround right now is to run Emacs from Terminal.app to inherit Terminal.app permissions.

P.S. There is a simple script that simulates the same behaviour if you want to check how it works: https://gist.github.com/dive/f64c645a9086afce8e5dd2590071dbf9

This is a simple patch to fix it (these changes are backwards compatible, and previous macOS versions ignore these values.):

Thanks for this.

I certainly confirm that the changes don’t break Emacs on macOS 10.14,
but not much else. :)

Artem, have you ever contributed to Emacs before? If so have you
signed the copyright assignment paperwork?

While I'd certainly encourage Artyom to start the legal paperwork
rolling, we don't have to wait to its completion to accept that
particular contribution, as it is small enough to not require
copyright assignment.  I don't see Artyom's name in our Git log, so
this must be hist first contribution.

I thought it prudent to check first. I’ll just push it now.

Thanks.

It was.  I wanted to answer that question.

Thanks.

I did not. Can you point in the right direction for the copyright assignment? I see the following page https://www.gnu.org/software/emacs/manual/html_node/emacs/Copyright-Assignment.html, but it is unclear how to request these papers.
