READ ME – Running the DEVONthink 4 Trial

Read this if you want to run a trial of DEVONthink 4…

Firstly…

DEVONthink 3 and 4 should not be available to run on the same account, on the same Mac.

Optimally, DEVONthink 4 should be installed on a separate macOS user account in its own ~/Applications directory to isolate it from other user accounts.

However, if you want to run DEVONthink 4 and use it with your DEVONthink 3 databases, you need to make sure version 3 can’t be launched.

  1. In the Finder, locate the DEVONthink 3 application.
  2. Control-click it, and choose Compress…
  3. After the ZIP file has been made, delete the DEVONthink 3 application - just the application. Do not run any uninstaller applications.
  4. Launch DEVONthink 4 and it will migrate settings and you can open databases just as you did in version 3. There is no database migration between the versions.

Obviously, the choice is up to you.

Secondly…

Take time to review the Help. At a minimum, the Getting Started section. And if you’re looking for AI information, read the AI Explained section there.

Lastly…

You should be diligent in your backups, especially local ones, in general and while testing our application.

Reverting back to DEVONthink 3

If you decide to stop testing and wait for the final release, the simplest thing to do is:

  1. Quit DEVONthink 4.
  2. Delete the DEVONthink application from the /Applications directory. Again, do not run any uninstaller applications.
  3. Decompress the zipped DEVONthink 3 file, then launch version 3. This should operate just like before with no need for any other action. This also leaves things intact for a future installation of the version 4.

If you would like instructions on deeper cleaning, please contact our support team.

Has anything really changed in DT4?

There have been some comments out on the Internet about whether anything has really changed in version 4.

The Version History in the Read Me section of the help shows the long list of changes in version 4 and many are not AI-related. There’s a lot of good information there.

However, it’s also a very trimmed down and summarized list of the changes. Otherwise, it would be too overwhelming to read. For a little perspective, here is an untrimmed view of the changes made during development (and even this isn’t 100% complete - and I hope you can see what a monumental task it was for me to pare this down)
