Now, it's time to allow your Mac to open any app.

Type of the following command syntax: sudo spctl -master-disable.

Be sure to exit System Preferences on your Mac.

The workaround makes it possible to download and use apps downloaded from anywhere on macOS Catalina and earlier versions without a check.įirst published in 2016 by OSX Daily, but still valid, the 'fix' works like this: A WorkaroundĮven though Gatekeeper in macOS is now stricter than ever, there is a way around it - including macOS Catalina's newest tools. However, some developers might view this differently and find the changes cumbersome, at best. If all this sounds fantastic to you, terrific. When your Mac detects a problem, it blocks the file, then sends you an alert.

Not just once or twice, but every time you run it. With macOS Catalina, perhaps more significantly, Gatekeeper will also check non-quarantined apps and files for problems. The difference: even on the first run, you only need to explicitly approve software launched in bundles, like a standard Mac app bundle, not for standalone executables or libraries.

These files get the same malware scan, signature check, and local security policy check. Now, apps started through Terminal are also checked. Significant changes have arrived with macOS Catalina. In other words, it checked an app only once for malware. It also didn't check non-quarantined apps and files for malware. Until now, Gatekeeper didn't take the same approach with apps launched via Terminal. If and when you try to open a quarantined app, Gatekeeper checks it for known malware, validates the developer signature to make sure it hasn't been tampered with, makes sure it's allowed to run, for example matches your settings for App Store apps and/or known developer apps, and then double checks with you that you really want to run the app for the first time, that it's not trying to pull a fast one and autorun itself. In his June article, The Great Mac Balancing Act, Rene Ritchie explains:Ĭurrently, when you download an app, whether it's off the Store or the Web or even from AirDrop, that app is quarantined. As its name suggests, the tool has been designed to check recently downloaded apps for known malware and sends it to quarantine. Gatekeeper has been an essential part of macOS for years.
