Completely stuck, help! Cannot install Mail plugin in Mojave?

[jimthing]

This is driving me absolutely insane!

Using: Mojave 10.14.6 + DT 3.9.6 (30 day trial). Yes, Full Disk Access enabled!

I need this plugin (according to reading threads here) in order to simply import my Mail.app's correct "On My Mac" nested folder structure correctly in one go. But I simply cannot even see any *.mailbundle* being installed, nothing is in the location specified ("Bundles" folder is completely empty), and all that happens is this error message constantly appears.

1. Bundles folder is created, but nothing appears in it (just get the error message above in DT).
2. Mail was quit during this whole process, and I never get any Plugins options ever appearing in the General tab either. Manually got it to show (see next post).
3. User permissions looks okay AFAIU?

I’ve tried all the threads where users have had the same issue, but NONE of the ideas have worked either!

DT3 - cannot install Mail plugin

Sequence: I had DEVONthink Pro Office 2 installed. Then I installed DEVONthink Pro 3. Then uninstalled DEVONthink Pro Office 2 using: UNINSTALLING To remove (uninstall) DEVONthink Pro Office completely from your Mac, trash the following files and folders (~ stands for your Home folder): DEVONthink Pro Office ~/Library/Application Support/DEVONthink Pro 2 ~/Library/Mail/Bundles/DEVONthink.mailbundle ~/Library/Preferences/com.devon-technologies.thinkpro.* All DEVONthink Pro Office-…

Cannot install Mail plugin

When I try to install the Mail plugin, I get: “Can’t copy plugin resources: Please check your write permissions and the amount of free space in your home “Library/Mail/Bundles” folder.” Permissions seem to be fine; plenty of free space. Anyone have any idea what’s going on? Many thanks!

Cannot install Mail plugin on DEVONthink 3.0beta7

I am unable to install the Mail plugin on two physically different machines. One is running 10.14.6 and the other 10.15 Beta (19A546d). Both machines give a message that Mail has disabled the plug-in. The message on 10.14.6 is: Mail has disabled the following plug-ins: DEVONthink.mailbundle Contact the makers of these plug-ins for versions that are compatible with Mail 12.4. and the message on 10.15 Beta (19A546d) is: Mail has disabled the following plug-ins: DEVONthink.mailbundle Con…

Problem installing the mail plugin

Hi I am new to Devonthink and am trying to install the plugin. I get this message “Apple Mail was never used for this login. Will not install plugin for it.” Appple mail is working on my computer. WHat do I need to do?

Cannot enable Apple Mail plugin: "Incompatible Plugin"

TY. This worked for me after migrating to a new MBP. I skipped the delete or rename directory part, but renamed the file only with a prefix of old - (etc). worked fine.

Not a very good first experience on attempting to use an app. I’m basically completely stuck with no way forward.

Minor thing done, but plugin still not installing…

I simply managed to get the Manage Plugins options to appear in Mail.app using this command then entering my password in Terminal [thanks to last thread post from user Dialabrain here].

sudo defaults write "/Library/Preferences/com.apple.mail" EnableBundles 1

But per second pic, none show as installed, due to the DT install error message (shown in the first pic in the first post).

You’re reporting something under control of the operating system there.

Does the behavior persist after rebooting the Mac?

Does the behavior persist after rebooting the Mac?

[jimthing]

Two restarts, I get the same thing. Before the second restart I uninstalled the app completely using CleanMyMac X, and then after restart re-downloaded and re-installed app.

The only thing I have now is this in my Trash:

Dumping this ZIP file in my Downloads, then unzipping there creates a file called DEVONthink.mailbundle.zip.cpgz - which is another archive format??

[BLUEFROG]

Okay, I have verified something must have changed relative to Mojave. Development will have to look at this.

On a side note, Mojave is old and not going to be supported in perpetuity. Any chance you can move up to a more modern OS?

PS:

DEVONtechnologies | A Word About Reinstalling

[jimthing]

Can you just upload/send me a copy of the plugin so I can just manually place it in the Bundles folder, please?

(my emails are on this mac, I want to archive “On My Mac” emails before updating to newer OS, for obvious reasons. To match my other mac on a newer macOS.)

[BLUEFROG]

It’s not a downloadable item.
As I said, development will have to look at this.

[jimthing]

Why’s that? Is it not just a .mailbundle file - per the other threads I read?

[BLUEFROG]

Regardless of the format, it’s not a separate download, e.g., available on our downloads page. It’s deployed as part of the application package.

[jimthing]

Shame it can’t be extracted? How long will it be before engineering can fix this?

[BLUEFROG]

It’s not simple matter of extracting it. The correct previous version would have to be determined first. Then decisions would have to be made on how best to handle the situation. Those are decisions development has to make.

Sorry but we don’t comment on development timeframes. They will see the thread and make their assessments.

[jimthing]

Okay. Looks like I’m screwed then.

Another interesting point… Is there a reason why the DT log popped-up advising me to strongly uninstall the “AdobePDFViewer.plugin” from Internet Plugins folder (which I did, and also left in my Trash; as you can see in the image above)?

[BLUEFROG]

@jimthing

Okay. Looks like I’m screwed then.

I’d call it waylaid momentarily, not the end of the world

PS: The Apple Mail plugin is not required nor the only option available. See DEVONthink’s Help > Tutorial > Handling Email.

Is there a reason why the DT log popped-up advising me to strongly uninstall the “AdobePDFViewer.plugin” from Internet Plugins folder…

Of course there’s a reason It has long been known to be crashy and it’s not required in a browser. It hasn’t been for a long time as browsers already provide a PDF plugin. And yes, it was able to crash DEVONthink as well.

[jimthing]

I’ll delete the Adobe then, thanks.

I read the Help and other forums extensively before trying to import any Mail. The trouble is that the nested folder structure simply does not show in the importer without the Mail.app plugin. It shows a single column of folders with no nesting. I’m not manually doing each folder one by one for hundreds of folders.

[BLUEFROG]

Check out that tutorial I mentioned for a quick overview.
Also, the Automation > Application Scripts section of the built-in Help and manual.

[jimthing]

Have to try those tmrw.

Before I go, are my permissions set correctly (see 2x Get Info panels above)?

[BLUEFROG]

If the current account has Read & Write access, that should be sufficient. It doesn’t install the plugin for all users.

Probably not for long.
