One more side note is that, Apple designed this Gateway method is for protecting your Mac from malicious malware. When you install Mac apps, plug-ins, and installer packages from outside the App Store, macOS checks the Developer ID signature to verify that the software is from an identified developer (Uninstall Program on Mac). All of a sudden my husband’s macbook could no longer open any OSX apps, including Safari, App Store, iMovie, Photos, etc. Once attempted to be opened, the app icons show a? Instead of the usual app icon. He would then get the following error: You can’t open the application because it may be damaged or incomplete.
- 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.

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.
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: How to stop auto open on mac for apps.
- Open your Mac’s System Preferences.
- Click on Security & Privacy, then go to the General tab.
- On the bottom left, you’ll see a padlock icon. Click on it and enter your admin password.
- 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:
- Go to your Mac’s Finder.
- 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).
- Right-click on the app.
- 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.
No apps will install on mac high sierra. To get the full installer: Method 1. Start the installer, which will download the missing files; Quit when prompted to restart; Copy (or move) the downloaded files from /macOS Install Data to a new SharedSupport folder inside /Applications/Install macOS High Sierra.app/Contents/.You can do that with.

One of the major changes in the macOS Sierra Public Beta isn’t an obvious one, and you may not encounter it until you try to install an app that you didn’t buy from the App Store.
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.

Apple is obsessed with privacy and security which is a good thing for us, the end-users. By default, macOS allows you to only run apps and software that are downloaded from the Mac App Store or identified developers. But if you want to open an app from an unidentified developer in macOS, then here are two ways to do so.
However, before we begin, a word of caution! It is a common and prevalent practice to insert harmful code and malware into apps and distribute/redistribute them. So, it is quite possible that a shady app that you torrented or got from an unverified developer might be infected and dangerous. If you understand the consequences and still want to proceed, here is how to override your security settings and open an app anyway from the unidentified developer in macOS.
How to Allow and Open App from Unidentified Developer in macOS
Step #1. Launch Finder on your Mac and locate the app you want to open. You are most likely to find this app in Downloads, Desktop or Applications folder.
Note: Do not use Launchpad as Launchpad does not allow a shortcut menu on apps.

Anytime in the future, you can open it by double-clicking just like you open other known and registered apps. As mentioned in the previous line, this does not change the whole relevant security settings of your Mac but merely creates an exception for this particular app. Everything else is just as secure as it was.

Are All Apps from Unidentified Developers Dangerous?
No. This is not necessarily the case. As Apple puts it, there may be some apps that were written before developer ID registration began. As a result, the app may not have been reviewed, and thus macOS can’t check whether the app has been modified or broken since it was released. Similarly, suppose you or your developer friend or someone you have been following for long and trust, build a simple app as a hobby. Is it dangerous? No! It is just not registered with Apple.
The safest approach to install an app from an unidentified developer is by finding a similar alternative app from the Mac App Store or identified developer. Sometimes paying for a similar app may also be a sensible solution than using a free unknown app. But if nothing works for you overriding the security settings and allowing apps from unidentified developers in macOS is a solution. In this sense, macOS is more flexible than iOS.
