In recent software updates, Apple has included more stringent security measures in its OS with the goal of better protecting your Mac from malware. While this gives you an added layer of protection, it also makes it more difficult to open applications that Apple is not familiar with (such as those not in the App Store or those created by unidentified developers).

Visit Apple’s support page to learn more about opening apps from unidentified developers. If you trust the developer, like an audio interface manufacturer, follow the steps below. Click the Apple icon and select System Preferences. Normally, if you want to close all of the open apps on your Mac, you'd have to either quit them all one by one or restart, shut down, or log out while making sure to deselect “Reopen windows when logging back in.' The latter option is great, but it doesn't always work in Mac OS X, and what if you don't want to restart, shut down, or log out?

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. With macOS Catalina, perhaps more significantly, Gatekeeper will also check non-quarantined apps and files for problems.

While it may be tricky, opening these apps is possible. Here, we’ll explain the reasoning behind Apple’s enhanced security, show you how to allow any and all apps on your Mac, and even briefly discuss keeping yourself safe from malware.

What does it mean to be able to download apps from anywhere?

Apple puts many safety measures in place in order to reduce users’ chances of being infected by viruses and other forms of malware. This is why Apple is known as a “closed platform”: It’s strict about what apps it allows to be easily downloaded onto and accessed from Apple devices.

The apps you can download onto an Apple device are generally limited to those that can be found in the App Store because they’re seen as more secure — they’re created by developers that Apple trusts and have been checked by Apple for malware.

In order to check an app’s safety, Apple uses a software called Gatekeeper.

Gatekeeper is Apple’s program that recognizes whether an app has been downloaded from the App Store. This program warns you when you’ve downloaded and attempted to run software from another location for the first time.

Downloading apps from anywhere, then, means accessing and using apps that either:

  • Don’t come from the App store
  • Were created by unidentified developers

It’s a good idea to know how to download and access these kinds of applications. So many of the great apps out there simply aren’t available on the App Store. This is a crucial skill for those who rely on apps that aren’t necessarily meant for Macs (such as Microsoft software), as well as those who have recently begun using Apple devices and want to be able to use non-iOS/macOS apps.

Luckily, your Mac does allow you to download apps from anywhere — it just requires a few more steps.

How to download apps that aren’t on the App Store or come from unidentified developers

There are two main ways to give your Mac access to a broader range of apps:

  1. Set your Mac to allow you to open apps that aren’t from the App Store
  2. Set your Mac to allow apps from unidentified developers

Both of these methods consist of changing your Mac’s Security & Privacy settings to allow you to open apps that haven’t been checked by Gatekeeper. Once you’ve bypassed Gatekeeper, you’ll be able to download and run all the apps you’d like. (To learn how to do this, check out our piece on how to open apps from unidentified developers.)

How to download apps from anywhere

Before macOS Sierra, it was much easier to set your Mac to allow you to download apps from anywhere. You’d simply go to System Preferences > Security & Privacy > General, then under Allow apps to be downloaded from, select Anywhere.

Since new updates to macOs, however, you’ll need to change a few more settings on your Mac in order to do so. Here’s how:

  • Launch Terminal by going to Finder > Applications > Utilities or by locating it with Spotlight search ([CMD] + [SPACE]).
  • In Terminal, type the code sudo spctl --master-disable and hit Return. Enter your Mac’s password when prompted.
  • Go to System Preferences > Security & Privacy > General. At the bottom of the window, you’ll see multiple options under Allow apps to be downloaded from. Select Anywhere to allow your Mac to download any and all apps.

If you later decide that you’d like to return to your Mac’s default settings and no longer allow apps to be downloaded from anywhere, just follow these steps:

  • Launch Terminal.
  • Once it’s running, enter the code sudo spctl --master-enable You’ll no longer be able to select Anywhere.

After this is done, you will only be allowed to download apps from the App Store, unless you use the steps mentioned above to access apps from other locations.

How to open Mac apps bypassing Gatekeeper

There is another way to open restricted apps that many Mac users don’t know about.

How many suspicious apps do you have?

You probably have downloaded apps from all kinds of sources. Some of them (especially, the dubious ones) may install additional components on top of their main functionality. Chances are, you wouldn’t even know.

Such invisible applications are sometimes called launch agents or daemons. They may stay in the background for years. Probably, you have a couple of those lurking on your Mac.

How to check your Mac for hidden background apps

To check it, you can run a free version of CleanMyMac X

CleanMyMac X itself comes from MacPaw, which is a popular Mac developer and its apps are notarized by Apple.

  • So, download and install a free version of CleanMyMac X.
  • Click on Optimization and choose Launch Agents

You’ll see background apps you can disable in one click.

  • In the same app, click on Malware Removal.

When it comes to finding suspicious apps and adware trojans, CleanMyMac X is way ahead of many other antiviruses.

CleanMyMac X will check your computer for all potentially unwanted apps (PUA) and all kinds of malware. It also helps you keep track of malware regularly with a real-time malware monitor.

A free version of CleanMyMac X is available here.

Is it safe to download apps from anywhere?

There’s no guarantee that apps downloaded from outside of the App Store will be safe. As these apps haven’t been vetted for security by Apple, it’s more difficult to confirm whether they’re safe and free of malware.

Because of this, you should be wary in changing your settings to allow apps downloaded from anywhere. Doing so leaves your Mac vulnerable malware and malicious software, as Gatekeeper won’t be able to check if the app downloaded is legitimate (or just malware disguised as the desired software).

The safety of your Mac, then, is in your hands. The best you can do to try to make sure that an app is safe to download is to look into its reviews and the experiences other users have had. Doing your due diligence can help you avoid using untrustworthy apps.

Downloading anti-virus software is another means of protection, as this software will check whether an app is safe for you. If, when researching all you can about an app, you decide you’d rather not download it, you can opt for a similar app with better reviews or one that is already in the App Store.
