I'm trying to open Parallels 14.01 on a Mac running High Sierra. I'm receiving the Parallels International GmbH security message. When I go to System Preferences/Security & Privacy there is no place to select allow Parallels International GmbH from. My only options are App Store or App Store and identified developers. I added Parallels to Privacy/Accessibility and there still is no option to allow Parallels to run. How can I fix this?
