For new Mac users, one of the most basic things to do on your Mac is install apps. However, with the Mac App Store being Apple’s default way to find and download apps, getting apps from the web and other sources isn’t as simple as it once was.
The reason for this is Gatekeeper, a feature that Apple implemented a while ago and tries to improve security for Mac users.
Let’s dig into more detail about what Gatekeeper exactly is, what it does, and how you can use (or disable) it to your advantage.
What is Gatekeeper?
If you have used earlier versions of Mac OS, you may have noticed that before running an application for the first time, a dialog box pops up telling you that the application was downloaded from the Internet and then requires asks you to confirm that you want to run. It. This feature is called File Quarantine, and it checks apps before you run them for the first time. It only works with files downloaded by other applications, such as web browsers or email clients.
However, there are some issues with File Quarantine because it doesn’t check for other types of installations, such as when you clone an application installer from a USB drive.
With Gatekeeper, on the other hand, only apps managed by Apple and available through the Mac App Store are allowed to run on a Mac, along with some other apps that have been ‘signed’ by ‘identified developers’ ‘, are developers registered with Apple .
When a developer has signed up for an external app (not available through the Mac App Store), Apple uses that signature to indicate who developed the app, when the developer signed the app that and, most importantly, whether the app is tampered with after leaving the hands of said developer. This allows Apple to blacklist a developer if it finds they have distributed malware, which would allow that developer to sign or distribute any other apps.
Using Gatekeeper
To enable or disable Gatekeeper, you will have to access your Mac System Preferences and choose Security & Privacy select.
There, click overview tab and make sure you’re allowed to make changes by unlocking the option at the bottom left of the screen.
Once you do, under Allow apps to be downloaded from: choose any of the following three options:
- Mac App Store: With this option, only apps downloaded directly from the Mac App Store will launch on your Mac. Things obtained from any other source will be rejected when you try to open them.
- Mac App Store and identified developers: As mentioned above, this setting will allow you to download third-party applications that are not available in the Mac App Store if signed by a developer. identified development. Personally, I think this is the best setting for most users.
- Anywhere: As the name implies, this option allows you to install any application regardless of its origin. Recommended for advanced users.
Once done, just close Interest control panel and back to work. Your app download will stick to the new install in no time.
Hot Tip: You don’t have to follow a setting. For example, if you find an interesting app that you know is trusted but is unsigned or available in the Mac App Store, you can adjust the settings above to any whereinstall the app and then set your preferences back to a more secure setting.
And there you go. Now that you have a better understanding of this essential feature, you’ll also know when to use it and tweak it to get the most out of it. Enjoy!
