How to open apps from unidentified developers on Mac OS X. There are numerous greats apps that are not present in the Mac App Store but installing a third-party app also brings the risk of bringing malware into your computer. 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.
Apple has a built-in way to protect you from opening up potentially malicious apps on your computer in Mac OS X. This setting, named Gatekeeper, will never stop you from installing apps from the Mac App Store, but it can help prevent helps from being installed that are not a part of the Mac App Store. However, if you get a security warning and still want to install the app, here is how to do it.
Choosing Your Gatekeeper Options
Open up your 'System Preferences' and head to 'Security & Privacy.'
In the 'General' tab, you'll see a section called 'Allow apps downloaded from.' In order to change these settings, you'll have to click on the lock icon below and input your admin password. Once that's out of the way, you can choose between three options:
- Mac App Store
- Mac App Store and identified developers
- Anywhere
Just the Mac App Store
The safest option to choose here would be the 'Mac App Store,' since Apple reviews all apps that are accepted in their store and can remove them quickly if necessary. You will know that your Mac will be as free as possible from malware if you use this option only.
Mac App Store & Trusted Developers
The next option also trusts apps from 'identified developers,' which are developers with a unique Developer ID from Apple who have their apps signed digitally. This is the preferred option, since Apple can verify that there has not been any tampering with the apps since they were signed.
Apps from Anywhere
The last option, 'Anywhere,' removes Gatekeeper's blocking capabilities on your Mac, letting you install and open any app off the internet, including Automator apps made by individuals. Sometimes Apps that fall in this category contain malware, We do not recommend using this option and instead recommend using the 'identified (trusted) developers' option above and okay installation of apps missing a Developer ID on a case-by-case basis.
Trusting Apps on a Case-by-Case Basis
If you have the 'Mac App Store and identified (trusted) developers' option selected, then when you download an app without a Developer ID and try to open it, you'll get the following warning.
- 'App Name' can't be opened because it is from an unidentified developer
To bypass this restriction, select 'OK' on the popup to close it, then go into the 'Security & Privacy' section in your 'System Preferences.' Below the Gatekeeper options in the 'General' tab, you will see the app that was blocked from opening. To trust it, select 'Open Anyway'.
An Even Shorter Way to Open Them
If you do not want to go into Systems Preferences to open an app for the first time as shown above, then Control+Click on the app in the Finder, then select 'Open.' You will see a new popup asking if you're sure you want to run the app on your Mac. Just hit 'Open' again and the App will launch as expected.

It could be that the software they have made is not seen as a suspicious thing, whereas inside there are codes that can steal your data which are profitable for a cyber-criminal. Based on this possibility, Apple made a policy that the software that can be installed by default is only the software made by an identified developer, so that we can have trust when installing and using the software.
Apple provides a gate for us so we can choose, download and install the application through the Mac App Store safely. Apple guarantees the software and its developers can be trusted, because everything is registered with Apple.
