To help keep your Mac safe, it won’t open apps unless they’re downloaded from either the Mac App Store or from an identified Apple developer. This is to stop malicious apps installing viruses and other malware on your Mac. But if you get a message saying an app you downloaded can’t be opened (but you’re sure you can trust the developer), you can open it using the following procedure.
Go to > System Settings (Ventura) or System Preferences (Monterey or earlier), then head to Privacy & Security, and find the Security section. Here, make sure your Mac is set to open apps from ‘App Store and identified developers’. There’s a message here about the last app you tried to open that was blocked. If – and only if – you’re sure the app is legitimate, click the Open Anyway button to open it.
