It's possible that there are files in some other user's trash. The .Trashes
folder at the top of each volume has subfolders for each different user, by user ID number (e.g. user 502's trash is in .Trashes/502
).
You can see if it for yourself using a command like this (replace VolumeName
with your drive name):
ls -la /Volumes/VolumeName/.Trashes/
total 0
d-wx-wx-wt@ 3 _unknown _unknown 102 10 Feb 18:15 .
drwxrwxrwx@ 21 root wheel 782 13 Feb 14:17 ..
drwx------@ 35 _unknown _unknown 1190 13 Feb 14:18 502
Note: you might get a permissions error from this command, either because the .Trashes folder doesn't allow read access (solve this by adding sudo
, e.g. sudo ls -ls ...
, and entering your admin password when requested); and/or because of the privacy protections in macOS Mojave (10.14) and later (solve this by granting the Terminal access in System Preferences > Security & Privacy pane > Privacy tab > Full Disk Access category, see here for more details).
As you can see, on my USB disk .Trashes
folder there's a sub foder called 502
, owned by user ID 502 (for reference, my current user ID is 501). Since this user doesn't exist on my system, I see it as _unknown
, and my user can't look inside of it, neither delete it. To look inside that folder we need to do it as administrator (i.e. use sudo
).
If you are sure that you want to, you can delete everyone's trash by deleting the entire .Trashes
folder with a command like:
sudo rm -R /Volumes/volumeName/.Trashes
Warning: as with anything involving sudo
("do as super user", i.e. system administrator) and rm -R
, use this carefully. If you type it wrong, it could have ... unpleasant consequences.
A program that is accessing files in the Trash that you're trying to Empty could interfere with attempt to Empty Trash.
The resulting timeout causes the "Stopping…" (which takes forever) alert message that you saw.
You can turn off Time Machine and try again or perhaps reboot (after turning off Time Machine) and see if the trash empties properly before starting up Time Machine or whatever other programs might have files open.

Open the trash folder, try to rename few sub files and main directory in which the file content and then try to empty the trash. By doing the same, it will not show error and will empty the trash.
For me this worked. Hope it also helps you.
