Can someone help me with this one? I have installed the plugin before with no problem, but recently I rebuilt the Mac using a fast SSD as my main drive and a normal SSD as my extended drive (its an iMac so I had few choices due to the internal blade SSD) so to make things more balanced, I moved my home folder onto the second SSD and everything is fine APART from the devonthink mail plugin. Its definitely due to the moved home account as I set up a trial account, logged in and its all working fine but that is all in the first smaller SSD so I cannot leave mine like that.
The install appears to work fine, but there is no plugin in the preferences pane to enable.
This is not a DEVONtech issue. It’s an Apple issue, and yes related to what you’re doing.
Check out these instructions from the SpanSieve developer, in the 7.1.1.1 If the Apple Mail Plug-In Doesn’t Appear in the List or Doesn’t Stay Enabled section…
I’m currently on Ventura and have the same problem. I’ve moved my home folder to a blade ssd and everything works except the DT3 mail plugin. When I try to install the DT3 mail plugin, my browser just opens up to the DT3 downloads page…but I don’t see any apple mail plugin to download. I’ve tried the steps in the replies above but I don’t think DT3 installed the plugin. Could someone help me with this?
