Method 1: Temporarily Run an App/File from Unidentified Developer Open the location where you have placed the downloaded app/disk image file on your Mac.

Many times we need to install apps which are not present on the Apple Mac OS X Store. In such cases we either download the app from external sources on the web. These apps prompt errors such as”app can’t be opened because it is from an unidentified developer” when we try to install them. In this tutorial we will show you two ways to Open & install Applications or Programs from Unidentified Developer in Mac OS X. This method has been tried & tested on Mountain Line, Mavericks, Yosemite as well as El Capitano too.

Pre-Requisites :

  • The Mac App package either in the .dmg , .pkg or .app file Format.
    • Non-Guest User account access in Mac OS X (Requires any User account with app-install permissions or Administrator account).

Method – 1 Method to Install App from Unidentified Developer Using Command Click .

  • Navigate & Open the Directory where your App package is located using Finder.
  • Now, When you try to Open it by double clicking the application file it will show an error as shown in the alongside image of “Unidentified Developer”.
  • In order to Bypass this error, Simply “press the control key and click your mouse button” or “right-click” the app file to open the app context menu as shown below –

    In the menu select “Open”.

  • After you click on Open it will create an exception in the Security preferences for the selected app and you will be able to Open & Install your favorite app! without modifying the Security Process at all.
  • This is perhaps the most easy way of Installing & Open an app from an unidentified developer.

Method – 2 Creating a Manual Exception for the App in System Preferences

The first two steps in this method are same as that of the first one –

  • Navigate & Open the Directory where your App package is located using Finder.
  • Now, When you try to Open it by double clicking the application file it will show an error as “unable to open app from Unidentified Developer”.
  • Now Click on the “Apple icon” on the toolbar and select “System Preferences” as shown below –

    In the System Preferences Window select “Security & Privacy” as shown below –

    Security & Privacy

  • Now, inside the Security & Privacy Window click on “General” tab at the top.
  • Here in General tab, Search for “Open Anyway” button under the label “Allow Apps from”. You will find the name of the app which you recently failed to install/open.
  • Now simply “Click On Open Anyway”. Congratulations! Your app would be successfully Opened & Installed on your Mac OS X.

Geeky Note – All Apps for Mac OS X need to be signed by Apple which is a paid process, and all developers cannot afford them. Hence, they directly distribute their app packages which are marked as “unidentified” by Apple. Please do check the App Source before you trust your downloaded app/Program.

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.

Mac Open Unidentified Developer

  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:

  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.

Should you make this switch?

Mac

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.
