1.10. Error: K3000.app cannot be opened because it's from an unidentified developer

Last Updated: July 2017

Applies to: Kurzweil 3000 Macintosh

Issue:

A user receives a security warning Kurzweil 3000.app can't be opened because it is from an unidentified developer when attempting to launch a downloaded version of Kurzweil 3000 on Mac OS 10.7+.

This issue may be encountered on computers with Mac OS X 10.7 or greater.

Solution:

Mac OS X 10.7+ has a security feature called Gatekeeper, that's built into the Security and Privacy settings in System Preferences. This essentially blocks all non-Apple verified software by default. To change this follow the below steps:

1. Go to Apple (your Apple icon at the top-right) > System Preferences > Security and Privacy > General Tab
2. Unlock the settings if necessary (in the lower left corner there is a padlock icon)
3. Under where it says Allow applications downloaded from: choose Anywhere

A nice walkthrough with screenshots is available here.
