As a Mac user, you might have heard of the term Gatekeeper. It is a built-in security feature in macOS that helps protect your Mac from malicious software. In this article, we will discuss what Gatekeeper is, its importance, and how to use it to safeguard your Mac.
What is Gatekeeper?
Gatekeeper is a security feature that was first introduced in OS X Mountain Lion. It ensures that you only download and install software from trusted sources, like the Mac App Store or identified developers. Gatekeeper verifies the digital signature of the app to ensure it hasn’t been tampered with or modified in any way.
Why is Gatekeeper important?
Gatekeeper is important because it helps protect your Mac from malicious software. When you download an app from an untrusted source, Gatekeeper will warn you that the app is not from a verified source. This can prevent you from accidentally downloading malware or other types of malicious software that can harm your computer or steal your personal information.
How to use Gatekeeper?
By default, Gatekeeper is set to allow apps from the Mac App Store and identified developers. To change the settings, go to System Preferences > Security & Privacy > General, and select the option you want under “Allow apps downloaded from.” Here are the options available:
- App Store: Allows you to download and install apps only from the Mac App Store.
- App Store and identified developers: Allows you to download and install apps from both the Mac App Store and identified developers. When you download an app from an identified developer, Gatekeeper will check the app’s digital signature to ensure it hasn’t been tampered with or modified.
- Anywhere: Allows you to download and install apps from anywhere, including untrusted sources. However, we recommend keeping this option disabled unless you have a good reason to enable it.
Conclusion
In conclusion, Gatekeeper is an essential security feature in macOS that helps protect your Mac from malicious software. By default, it is set to allow apps from trusted sources, but you can change the settings if you want to download and install apps from other sources. So, make sure you use Gatekeeper to safeguard your Mac and keep it secure from security threats.
