The DEVONthink plugin for Apple Mail (ver 4.0.7) is reported as being incompatible with Apple Mail version 16 on macOS Monterey (12.6.3). I have manually deleted the bundle from the user library location and reinstalled the plugin through the DT “Install Add-on” preference panel.
Can someone tell me if there is something that I can do to make the DT mail plugin work with the current version of Apple Mail?
Did I reenable the plugin in Mail’s preferences? Yes.
Has none of the threads regarding this issue turned out to be helpful? Correct. I have followed all of the various recommendations that I’ve seen from @BLUEFROG (especially) and still I get the same message from Apple Mail that the plugin is incompatible and will be disabled.
Do you have any suggestions on my issue? Regardless of what I do to reinstall the DEVONthink Mail plugin, I get a message that the plugin is incompatible and needs to be updated to work with Mail ver 16.
Remove the installed plug-ins from ~/Library/Mail/Bundles and ~/Library/Application Support/Mail/Plug-ins/Bundles/Users/<Your Username>/Library/Mail/Bundles and then install it again. Does this work? Please ensure that DEVONthink has full disk access.
Following @cgrunenberg’s comments, if that doesn’t work, try this…
In the Finder, press Command-Shift-G and type: /system/library/mail . If the directory exists, open it and check the Bundles directory for a copy of our plugin. If you find one, remove it. Then open DEVONthink, reinstall the plugin, then re-enable it in Apple Mail.
