If you’ve ever tried to open an app from an unidentified developer on your Mac, you know that it can be a tricky task. macOS has security measures in place that block this action in the hopes of protecting you from malware. That being said, it’s not impossible.

1. Apr 07, 2017  You’ll be warned that the app is from an unidentified developer–in other words, it isn’t signed with a valid developer signature. If you trust the app, click “Open” to run it. Your Mac will remember this setting for each specific app you allow to run, and you won’t be asked again the next time you run that app.

5. Option 3: Disable Gatekeeper security feature temporarily. Here is a step-by-step guide on how to disable Gatekeeper temporarily: 1.Click on the App that you have downloaded from a third-party developer; you will not be able to open the application and will be blocked automatically.

Is your Mac stopping you from opening an app from an unidentified developer? If an app you want to open is being blocked here's how to override macOS's security measures so you can open all apps. Nov 09, 2019  in this video i will show you how to allow apps (Software) from unidentified developers on your macbook, macbook pro, macbook air, macmini, imac act run macOS Catalina.

Here, we’ll talk about apps from unidentified developers and show you how to allow them on your Mac. We’ll also go over some tips for staying safe when downloading new software.

What is an unidentified developer?

An unidentified developer is an app developer that isn’t registered with Apple. Generally, apps from unidentified developers haven’t been reviewed by Apple for safety and security.

Apple believes that one of the easiest ways to distribute malware is to insert its code into an app. That’s why they check apps thoroughly before allowing them to release to the Mac App Store. Apps from unidentified developers aren’t on the App Store.

This doesn’t mean that apps from unidentified developers are malicious (although they can be). They can either not comply with Apple guidelines, or be created before the ID registration started.

Why your Mac shows a warning?

In order to protect your device from dangerous apps, Apple includes security measures in their devices. One example of this is 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.

When you receive a warning about an app, it’s because Gatekeeper flagged it as a potentially dangerous app. This doesn’t necessarily mean that the app has malware—it simply means that macOS doesn’t recognize the app (or the developer). Because of this, you won’t be able to open the app as easily as you would an app that’s been vetted and listed on the App Store.

Luckily, it’s a bit easier to download apps from unidentified developers onto your Mac than onto other Apple devices.

How to set your Mac to allow apps from unidentified developers

By default, your Mac is set to block you from opening apps that haven’t been verified by Gatekeeper. This includes both apps that aren’t from the Apple App Store and those that come from unidentified developers.

It’s a good idea to start by first setting your Mac to allow you to open apps that aren’t from the App Store.

Setting your Mac to open apps not from App Store

By setting your Mac to open apps that aren’t from the App Store, you reduce the number of warnings you’ll get when opening third-party applications. This makes it much easier to open these kinds of apps.

Here’s how to change your Mac settings to allow apps from third-party locations:

1. Open your Mac’s System Preferences.
2. Click on Security & Privacy, then go to the General tab.
3. On the bottom left, you’ll see a padlock icon. Click on it and enter your admin password.
4. Under “Allow apps to be downloaded from”, select App Store and identified developers.

Once this is done, you’ll be able to open most of the apps that aren’t on the App Store. However, you still won’t be able to open apps that aren’t recognized by macOS.

Setting your Mac to open apps from unidentified developers

If you want your Mac to allow apps from unidentified developers, you’ll have to follow a few additional steps. Firstly, try to open the unrecognized application. You’ll see a notification that it can’t be opened. Then, follow the instructions:

• Open System Preferences.
• Click on Security & Privacy, then go to the General tab.
• You’ll see the message “[App] was blocked from opening because it is not from an identified developer.” Clicking the button next to it marked “Open Anyway.”
• You’ll be asked again if you’re sure you’d like to run the app. Click the Open button to run it.

These steps allow you to open this app whenever you’d like. You should remember, though, that Gatekeeper won’t allow you to open apps that contain malware, even after following these steps.

Apple’s recommended way to open apps from an unidentified developer

Apple knows that Mac users still want to open apps from unidentified developers. Luckily, they’ve provided a method for doing so.

Here’s how:

1. Go to your Mac’s Finder.
2. Find the app you tried to open. If you’re having a hard time finding it, you can search for it in Finder or using Spotlight search (Command-Space).
3. Right-click on the app.
   
4. On the menu that pops up, click Open, and the app will open like any other.

Following these steps will make this app an exception, allowing you to open it again.

Opening apps from anywhere

Earlier versions of macOS used to provide the option to “allow apps from anywhere.” This would allow you to open any app without having to go through the above steps for each one you’d like to open.

While convenient, this can be dangerous, as it can leave your Mac open to malware. This is likely why it’s been hidden as a readily available option.

Are apps from unidentified developers safe?

Because they require circumventing Apple’s default security vetting process, it’s harder to determine whether apps from unidentified developers are safe. You’ll need to be sure yourself that a particular app can be trusted.

The best you can do to ensure that an app is safe to open is to do your research on it. Read through some reviews and look into the experiences other users have had with the app, as these sources are the most likely to give you truthful and relevant information. Dig as deeply as you can to help avoid downloading any dodgy apps.

You should also ensure that you have antivirus software (and that it’s up to date). This adds an extra layer of protection to your Mac. If you find that an app isn’t trustworthy, opt for an alternative app in the App Store or one from an unidentified developer that you can trust.

Keep your Mac malware-free

Downloaded a suspicious app? CleanMyMac X allows you to check your Mac for potentially unwanted apps (PUA) and malware with its Malware Removal Module. This feature scans your Mac for malicious apps and allows you to delete them one-by-one or in bulk. CleanMyMac X also features a real-time malware monitor to help you keep track of whether you’re not downloading anything malicious.

Here’s how to use it:

• Get the app on your Mac.
• Launch CleanMyMac X and go to Malware Removal.
• Press Scan.

If CleanMyMac X has found any threats, press Remove to delete them. Additionally, you can free lots of space on your Mac by deleting outdated cache files, system log files, and other unused junk with the System Junk feature.

Now, you know how to install any app on your Mac and circumvent the restrictions. But, if you aren’t vigilant enough, you may need to deal with the consequences of malicious software. It’s a good idea to always question the apps you want to install and look for additional reviews and testimonials.

Over the years, Apple has put its vast resources into making it's operating systems more secure for end-users. In macOS Catalina, the company has taken this to all-new levels by introducing beneficial security changes that make it even harder for miscreants to play havoc with our computers. However, because security is a tricky business, so-called improvements for some might not work for others. Specifically, Apple's decision to make Gatekeeper even more difficult crack is a significant step forward for everyday Mac users. For developers, perhaps not so much. Luckily, there's a workaround.

Warning: This terminal trick disables important security aspects of Gatekeeper, which leaves your Mac vulnerable to malware. We highly recommend you reinable the default security settings if you chose to follow this guide at your own risk.

What is Gatekeeper?

Gatekeeper has been an essential part of macOS for years. As its name suggests, the tool has been designed to check recently downloaded apps for known malware and sends it to quarantine. In his June article, The Great Mac Balancing Act, Rene Ritchie explains:

Currently, when you download an app, whether it's off the Store or the Web or even from AirDrop, that app is quarantined. 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.

Until now, Gatekeeper didn't take the same approach with apps launched via Terminal. It also didn't check non-quarantined apps and files for malware. In other words, it checked an app only once for malware.

Significant changes have arrived with macOS Catalina.

Now, apps started through Terminal are also checked. These files get the same malware scan, signature check, and local security policy check. 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. Not just once or twice, but every time you run it. When your Mac detects a problem, it blocks the file, then sends you an alert.

If all this sounds fantastic to you, terrific. That's undoubtedly Apple's intent. However, some developers might view this differently and find the changes cumbersome, at best.

A Workaround

Even though Gatekeeper in macOS is now stricter than ever, there is a way around it -- including macOS Catalina's newest tools. The workaround makes it possible to download and use apps downloaded from anywhere on macOS Catalina and earlier versions without a check.

First published in 2016 by OSX Daily, but still valid, the 'fix' works like this:

1. Be sure to exit System Preferences on your Mac.
2. On Finder, click Go.
3. Select Utilities.

4. Double-click Terminal.

5. Type of the following command syntax: sudo spctl --master-disable .
6. Hit Return
7. Authenticate with an admin password.
8. Hit Return.
9. Exit Terminal.

Changing your settings

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

1. Click on System Preferences on your Mac Dock.
2. Choose Security & Privacy.

3. Tap the lock at the bottom left of the screen.

4. Enter your password to unlock Security and Privacy.
5. Choose the Anywhere under Allow apps downloaded from. Prior to making the change, this option wasn't available.

6. Click the unlocked lock to keep the change.

With this change, Gatekeeper no longer monitors your computer for malware coming from apps and files.

Restoring to the original setting

If you'd like to return to the default Gatekeeper settings, perform these steps:

Allow Software From Unidentified Developer Mac

1. Be sure to exit System Preferences on your Mac.
2. On Finder, click Go.
3. Select Utilities.

4. Double-click Terminal.

5. Type of the following command syntax: sudo spctl --master-enable .
6. Hit Return
7. Authenticate with an admin password.
8. Hit Return.
9. Exit Terminal.

View the change

To confirm your Mac has returned to the default settings:

1. Click on System Preferences on your Mac Dock.
2. Choose Security & Privacy.

Under Allow apps downloaded from, notice the select is now App Store and identified developers.

Allow App From Unidentified Developer Mac

Should you make this switch?

For nearly every Mac user, there's no reason to make the listed change under Security & Privacy on macOS Catalina. It should only be performed if you can quickly determine whether apps are legitimate or not. Keep this in mind.
