If you’re updating the Neat scanner software to the 4.0.3 version, you may receive a message stating “The update is locked with a password.”
This message is misleading.
On Apple computers, sometimes software installations or updates will require the username and password of an administrator account. In this case, the password being requested is your computer user password (the password you might type to login to your computer).
So, the software update isn’t locked as the error message suggests. It simply needs authentication and permission to install.
