Installing apps on Mac is easy. All you’ve to do head over to the App Store, search for the app and install it. That’s what Apple recommends. Installing apps from other sources is never easy and will be blocked when tried to install even after downloaded. They are blocked by a specific security feature which is called Gatekeeper.
This feature blocks unknown apps for security reasons that are out of the App Store. Installing unidentified apps out of the App Store is not checked from Apple and might make some problem. This useful feature is on most popular operating systems like Windows but in a different form. While there are many reasons for this feature, one of the reasons for this is the security reasons and also because most apps are on the App Store and there’s not much required to install.
Oftentimes are when you will need to install an app that are not in the App Store list. At this point, there’s likely you’ll see an error of the “System Extension Blocked”. This is certainly pointing to the security feature that is blocked by the Gatekeeper. Like fixing macOS Catalina Screen Resolution on VMware. But this feature is probably modifiable.
By default, when macOS is installed, Gatekeeper is set to allow apps from the App Store and identified developers. This setting can be however changed to allow installation from unknown sources which will fix the problem. This problem can appear on macOS Catalina installed on VMware or install macOS Catalina on VirtualBox or on actual Mac. Doesn’t matter where it is installed, it will allow the installation of third-party apps no matter where they are installed. Here’s how to fix the error and enable the installation of third-party apps from everywhere.
Allow Third-Party Apps to Install on macOS Catalina
Making a change to this will take apps not install but function properly and run all the way through. This trick works with macOS Catalina and the previous versions. This happens mostly when you install VMware Tools which is the primary step to run. This is the easy and comfortable way.
Go ahead and open Terminal from the Spotlight.
Next copy and paste this command then hit Enter. Enter your password when it asked.
After that done, it will allow third-party apps all the time and that’s all.
At the end, it will definitely do the thing that after it, you will be able to install any app you want to. It has added the third option which is Anywhere that will certainly allow third-party apps to install and run properly. So now you can install any app but safe one to work with.
After this, your Mac will not even ask one single time but you’ve to probably be careful and install only safe apps. Afterall, if you want, you can change it from the Security and Privacy tab to another option. This is probably the best way.
