In macOS 10.15, quarantined plug-ins will return one of the following errors:
This happens with plug-ins that are not notarized that are downloaded from the web or installed by other methods such as drag & drop.
Obtain updated plug-ins from third-party developers that are notarized for macOS 10.15. InDesign will load plug-ins that have been notarized by Apple.
For older plug-ins that are not notarized, customers with Admin user privileges can remove the quarantine flag by using the following command if the plug-in is installed in the InDesign application plug-ins folder:
sudo xattr -r -d com.apple.quarantine /Applications/Adobe\ Indesign\ 2019/Plug-ins/<plug-in-name>
Determining whether a plug-in is quarantined
Customers can determine whether or not a plug-in is quarantined by using the Terminal.
Example if plug-in is in the Indesign application plug-ins folder:
% ls -l@ /Applications/Adobe\ Indesign\ 2019/Plug-ins/<plug-in-name>/
Note: replace <plug-in-name> with the actual name of the plug-in you need to correct
Which returns the following result:
total 0 drwxr-xr-x@ 6 <username> wheel 192 Sep 26 15:11 Contents com.apple.quarantine 22
"com.apple.quarantine 22" means that the plug-in is quarantined.
