I’m pretty sure that almost all of you got this annoying issue. It happens when you upgrade to macOS Sierra or higher because Apple does not allow untrusted app to install into your mac. Maybe that’s good way to protect you, but sometimes it makes you annoyed.
Yeah so I’m gonna help you to fix it, follow me 😀
Open Terminal in Application, then type these command line:
sudo spctl --master-disable
Your mac password will be required. Just type it and hit enter.
You done ^^
That’s it, too easy right 🙂
