I updated to macOS Catalina which requires the user through pop-ups to allow any app trying to access the file system for the first time.

No such pop-up is appearing for Emacs. Running the script shared here, https://gist.github.com/dive/f64c645a9086afce8e5dd2590071dbf9
does not seem to change anything. That is, Emacs and any shell running in it cannot access any file on the file system.

How can I restore the access?

My Emacs version is *GNU Emacs 26.1 (build 1, x86_64-apple-darwin14.5.0, NS appkit-1348.17 Version 10.10.5 (Build 14F2511))

UPDATE
Granting the Emacs app Full Disk Access in "General Settings -> Security & Privacy -> Privacy" does not solve the problem.

  • Go to "General Settings -> Security & Privacy -> Accessibility" and add there Emacs, to allow it to control your computer. Then trying to open a file from Emacs will open a short dialog asking to confirm permission for that folder. The allowed folders will appear in Privacy -> File and Folders. Maybe it will be useful to upgrade to Emacs 26.3 – Ian Oct 8 at 14:36
  • Thanks, Emacs was already allowed under Accessibility. I removed and re-added it. I also re-installed and thus upgraded to Emacs 26.3 in the meanwhile. All to no avail! – wsaleem Oct 8 at 14:45

Emacs.app actually launches using a ruby script. As a result, MacOS Catalina uses the permissions set for ruby, not the permissions for Emacs.app. Granting /usr/bin/ruby full disk access in "General Settings -> Security & Privacy -> Privacy" should resolve your issue.

/usr is hidden by default on MacOS but you can toggle visibility in the Finder by using Shift+Command+Period

  • @Chris's answer is right, or you can launch emacs in the terminal, which also resolves your problem. – Gilbert Wong Oct 9 at 2:53
  • Thank you! Worked great. I had to go back to "Security & Privacy" and click on General (after granting ruby access and trying emacs). And found that I had to "Allow apps downloaded from - App Store and identified developers. I ended up doing this twice. Looks like emacs is using some legacy stuff and that os x is checking more things that are not theirs. BUT worked great after that, so full access to ruby and then the legacy stuff and it worked. Outstanding post, thank you! – EvanCharlesSmith Oct 9 at 11:59
