I use Mac osx with a Mac server. It seems that the problem was solved in version 2022, but only by connecting with SMB protocol. It's very annoying because AFP is much stable.

Still not fixed in 2022!
Adode InDesign does not get external volumes permission in the MacOs Security Preferences Panel, so the "reveal in finder" does not work on external volumes.
Very painful.

The same thing is happening on my computer. It is the dumbest bug! When is this being fixed????

Same is happening here with reveal in Finder from the Links panel (Mac OSX Big Sur, InDesign 16.1).

The same thing happens for me but on a connected Raid drive.

Same here on my local HD. Indesign 16.0 on Catalina

Same here with InDesign 15.0.2 on Catalina

Same problem with a directly connected raid array.

Tnks so much i hope this issue can be fixed soon, i work whit many files and if this working my life is too easy hehehehe :)

Confirmed on two of our machines here, doesn't work with any external volume. It's related to Catalina permissions, the Photoshop and Illustrator team got the Catalina privacy memo from apple, but InDesign team did not. Check your permissions in System Preferences. I do not have InDesign asking for access to any External Volumes or anything else, but I think my designer does (though it doesn't work on this machine either).

I also have the same issue. I can add that in Mojave as the same ad user, it works.
I wonder, if it has something to do with the new security settings in Catalina under "Files and Folders". I have Desktop and Network Volumes checked. I am running 10.15.3 on a an imacpro.

Same here, however, it works if i take any of the linked files in the link-window and right click on them to "reveal in finder"

Same here with InDesign 15.0.1 on Catalina

Same here

Me too same problem, do you have new OS X CATALINA?

If I click on the right button on the file name (SHOW ON THE FINDER) the folder containing the File is not opened.
