Can't install a .mpkg file - a Security Preferences issue?
I'm having the issue installiung a .mpkg file - it's an App from Pantone.
The message says "Your security preferences allow installation of only apps from the Mac Store and identified developers"
I went into the "get info" and made sure that "Installer" was selected under "Open With:" but that didn't fix it.
