I get this error message when trying to install the software on my hard drive. and my computer won’t install. Is there a solution? “NegativeLabPro-OSX-2.1.2” cannot be opened because the developer cannot be verified.
The newest Mac OS just makes it unnecessarily difficult… you need to:
"control + click" then select “open”, then select "open"
If that doesn’t work, you may need to go into your “Security & Privacy” preferences, and enable apps from third parties.
