Docear unable to start on Mac

Mac OS X 10.9.x requires all software to be signed. Docear is not signed yet, but there is help. Please find official informationhere or read:

  • When you have never used Docear before you can start it by switching in your system preferences -> security -> allow apps from anywhere. You can also right-click the app, open it and select that you want to execute it although it is not signed.
  • When you have already used Docear and upgrade to a newer version of Docear, OS X 10.9.x fails to verify the Docear app and reports that it was tampered.

To solve this issue you need to open a terminal shell and execute the following commands::

This will return a line with an ID and some additional information like this: 3529[UNLABELED] P0 allow execute [/Applications/Docear.app]

Then you need to remove it.

# e.g. with an id of 3529. It may be different for you.

Next you have to tell the system to put Docear.app back in quarantine to test if the signature is valid again and we can use the right click method again.

# your app location can be different.

Now the application will open when you right-click it and press OPEN.
