I'm using an iMac. When I try to open Black Book 2 to retrieve my passwords, I receive the following error: "xcrun: error: cannot be used within an App Sandbox". What can I do?
You receive this error because your computer considers that Black Book 2 is not a safe application. It is using a technique called App Sandboxing. You can read more about it on the official web page. In order to fix the issue, you will need to add a temporary exception. To do this, I recommend you check the App Sandbox Temporary Exception Entitlements article. If you have issues, I recommend you contact Apple support team.
