Maybe this one change in macOS Sierra slipped by until you needed it most. Or maybe you didn’t discovered this little shift until you tried to install a favorite app that you didn’t download from the mac app store. Whatever the manner, you learn the hard way that macOS Sierra’s made invisible the usual method to open apps downloaded from anywhere!
The settings was until recently found in the General tab of the Security & Privacy System Preference. But no more, not with macOS. So if you really need that app and can’t figure out how to get it open, it’s frustrating. No, it’s very frustrating that our macs just aren’t working the way the used to!
Since OSX Lion, Apple’s mac operating system includes a security tool named Gatekeeper. This feature prevents downloads of software and apps from unidentified developers. Gatekeeper assumes the app is trouble when the app you want to download is not signed with Apple. And it does not allow that app onto your mac computer. For most mac users, this is a very good thing and helps keep their computers safe and secure. But their are a lot of us iFolk who absolutely need and want the ability to download AND open apps downloaded from anywhere.

So What is this Gatekeeper Anyway?
In theory, Gatekeeper protects your mac from apps that potentially have adverse affects. It works by not allowing unsigned apps from downloading and opening on your mac. Apple prefers that all 3rd party apps go through its signing process. Developers register with Apple and a unique Developer ID identifies each developer. This ID is then used in testing and validating the app for Apple products. Apple reviews, approves, and accepts all signed apps. Once accepted, the app then officially supports Gatekeeper. And users are able to download and open these apps via the mac app store.
Apple views this method as the safest and most reliable to download new apps onto your mac computers. They believe that downloading apps exclusively from the mac app store translates into reduced hazard. And since Apple’s reviewed the app, if there’s ever a problem, Apple quickly removes it from the mac app store.
Consequently, if an app is developed by an unknown developer with no Developer ID, Gatekeeper blocks that app from being installed and opened. However, there are a lot of great apps out there, particularly open source apps, that for numerous reasons are not available via the mac app store. Many of these third-party apps are thoroughly tested and have worked on macs and other computers for ages. Either by choice or chance, these apps are not currently available in the mac app store.
What About the mac app store?
It’s easy to think that the mac app store works exactly like the app store for iPhones and other iDevices. But not so! Since the mac app store opened, mac computers have always allowed you to install applications not available in the store. Before there was a mac app store (2011), installing applications via third-party websites or installation discs was the norm. Plus, developers must pay a percentage to Apple when you purchase apps from the mac app store. When purchased directly through the developer, there is no additional fees for Apple, keeping costs lower for all of us users. So for these reasons and more, many apps are not included in the mac app store.
Mac users continue (and will continue) to get apps directly from developers sites or old-school via installation discs. The long and short is that the mac app store is not the only way to get apps. So getting around this macOS default is pretty important!
Where is Setting to Open Apps Downloaded from Anywhere?
In previous versions of its mac operating system, there was a checkbox option in System Preferences>Security & Privacy allowing you to download apps from anywhere. However, macOS Sierra introduced a Gatekeeper that’s a heck of a lot more strict than in the past. In this newest os incarnation, Gatekeeper defaults to only allowing options for apps downloaded from the app store or the app store and identified developers. So for us iFolk that want or need to download an app from a source we trust but Apple currently does not trust (or identify), what to do?
We need that third option, the option to “allow apps downloaded from anywhere” that seemingly disappeared with our update to macOS Sierra.
Luckily, there are a couple of ways to circumvent Gatekeeper’s defaults so when we want or need to, we can indeed open apps downloaded from anywhere.
So let’s get to it!
How-To Open apps Not Available in the app Store
The Super Easy Way to Bypass Apple Defaults and Open apps Downloaded from Anywhere
So if your trust the app and its unidentified developer, then there is a really easy way to open that app.
And it’s surprising how simple this method is and basically involves a single click. To selectively bypass Gatekeeper, just Control Click (or Right Click) and choose Open from the menu options. A message appears warning you that the app is from an unidentified developer and asks if you are sure you want to open it? If you are confident in the app’s source, click Open. That’s it!
This option works for single apps. It does update your computer’s internal list of identified developers so in the future, macOS recognizes the developer as “identified.” But this method does not make universal updates to your Security & Privacy System options. It’s a one and done option, for times when you want or need to download and open a particular app that is currently NOT available in the app store. (i.e. the app is not signed.)
Another, Slightly Longer Way to Open apps Downloaded from Anywhere
Assuming you trust the app, after downloading move it to your Applications folder. Now, try to open it. You likely see a warning that the app “can’t be opened because it is from an unidentified developer.” Select OK. But this does not actually open the app.
Now, go to System Preferences>Security & Privacy and select the General tab. Look at the section “Allow apps downloaded from:” and see if the app you just attempted to open is listed with a button “Open Anyway.” If so, click this button to open that app. Be aware that the “Open Anyway” button is only available for around 1 hour after you first try to open the app.
macOS takes note of that app and developer and add it to the operating system’s list of identified developers (for this mac only.) If you ever download another app from this same developer, macOS checks this internal list. If the developer is listed, macOS open any app from that developer.
About the Unidentified Warning Message
When you open an app that is not registered with Apple by an identified developer, you see a warning message box. Seeing this message does not mean there’s something wrong with that particular app. Developers wrote many of these unidentified apps before developer ID registration began. And others choose not to register for various reasons from cost (Apple charges a yearly developer fee) to conviction.
The unidentified developer warning means that the app you want to open has not been reviewed by Apple. Consequently, macOS is not able to check and verify if that app has been modified or broken since it was released.
Once you open an unidentified app, that app is saved as an exception to your security settings. From now on, you open it by double-clicking as normal.
Terminal Is At Your Command to Open apps Downloaded from Anywhere
Use Terminal to update our Security & Privacy options to include the checkbox allowing us to open apps downloaded from anywhere. And it’s actually pretty simple to make this modification.
Although simple, for the average mac user this step is not recommended . Before you download and open an app that Apple does not currently recognize or identify, make sure you (or your company) fully trust the app’s source and its validity. Modifying this security setting puts your computer at potential risk and makes your mac more vulnerable to some malware and other malicious junkware. So, proceed with caution and double (or triple) check the trust factor of any app before downloading and opening.
Allow and Open apps Downloaded from Anywhere
- Quit System Preferences and all open applications
- Open Terminal
- Located in /Applications/Utilities/ folder
- Type in sudo spctl –master-disable
- Press Return
- Type your admin password to confirm
- Open System Preferences>Security & Privacy
- Select General Tab
- Verfiy that “Allow apps downloaded from:” now shows “Anywhere” as an option
Now, you are able to install and open apps downloaded from anywhere under macOS Sierra. Using this command turns Gatekeeper off and allows apps from anywhere including unidentified developers. Apple issues warnings that these unidentified developer (unsigned) apps possibly make your mac more vulnerable to malware and junkware.
Reverse to Original macOS App Settings
To go back to the macOS default settings, repeat the steps above substituting step 3 with enableinstead of disable at the end of the command.
So step 3 reads like this:
sudo spctl –master-enable
This returns macOS Gatekeeper back to its strict default and disallows unsigned apps from downloading and opening.
Checking the status of Gatekeeper
To check the status of Gatekeeper on your mac without opening System Preferences, it’s as simple as one command. Open Terminal and type the following command: spctl –status. Then press the return key. And you get a response of either “assessments enabled,” meaning Gatekeeper is ON and ACTIVE. Or you see “disabled,” meaning Gatekeeper is OFF and INACTIVE.
A Word For the Wise
When you receive the message “app can’t be opened because it is from an unidentified developer,” take a close look at that app and ensure that you trust its source before downloading and opening. This warning is there to protect your computer and you from harm and malware, so don’t just simply ignore it. Be mindful and careful when downloading apps not currently offered on the mac app store.
With that said, there are a host of wonderful third party apps that are not currently offered in the mac app store. Many of these apps are under review and not yet accepted. Still others do not seek approval based on conviction and values. So don’t discount a good app just because it’s not offered in the mac app store. Do your research and check out an app’s source before deciding to download or not. Think of great apps like NeoOffice that for the longest time wasn’t available on the mac app store but now is!

One of the best things about a Mac is the range of free apps that come pre-installed. However, that doesn’t mean you won’t download and install other applications from time to time. It should be easy — like most Apple tasks — but that isn’t always the case. This post explains what you can do if your Mac won’t install apps.

Common error messages when installing Mac apps
When trying to download or update apps, you might get one of the following messages:
- “App can’t be opened because it is not from the App Store.”
- “App failed to download. Use the Purchases page to try again.”
- “The application could not be downloaded. The installation could not be started.”
If this, or something similar, has happened to you, we have the solution below. But first, let’s make sure you’ve got the basic requirements to install an app.
What do you need to install apps on a Mac?
In order to download, install, or update an app on your Mac you will need the following three things:
- a good Internet connection
- ample free storage
- an administrator password.
Check your Internet connection by streaming a video online. If the video is slow to load, contact your Internet service provider for assistance.
Check your storage by clicking the button in the menu bar and selecting About This Mac > Storage. Ensure you have at least as much space as recommended by the app developer. Preferably a bit more.

You’ll often need an administrator password to complete the installation of an app. If need be, ask the administrator to log on and install the app themselves. Otherwise, they may need to enter their password when prompted from your account.
How do I open apps that aren’t from the App Store?
Macs benefit from a lot of in-built safety precautions, but when downloading third-party apps they can sometimes appear overzealous. By default, your Mac won’t install apps from anywhere other than the App Store, although this is easy to bypass.
After downloading an app, control-click the file in your Downloads folder and select Open from the menu. You’ll get the same ‘unidentified developer’ warning as before, but this time you’ll have the option to open the app anyway.
You can reduce the frequency of these alerts by going to System Preferences > Security & Privacy > General. Click the padlock and enter your administrator password to unlock the settings, then choose to “Allow apps downloaded from: App Store and identified developers.”
Update macOS and reboot your Mac to reduce issues
Update macOS to the latest version, unless it isn’t compatible with the app you’re trying to use. Developers typically list the recommended operating software wherever you download the app from.
Check for updates in macOS by clicking the button in the menu bar and selecting About This Mac > Software Update.
A reboot of your Mac is another effective troubleshooting tool. Shut down your Mac using the button in the menu bar, and leave it powered off for a minute or so before powering on again. After doing so — and allowing all the background processes to close down and start again properly — your Mac is likely to run with fewer issues.
Delete the app and then try to install it again.
Before deleting any apps from your Mac you should make sure you have a recent backup of all your valuable data.
Where Are The Apps I Downloaded On My Mac Download
It could be that the app, or the app installer, has become corrupt and this is why your Mac won’t install or update it. The only remedy for this is to remove the app from your machine entirely and download it again from scratch.
Close down any version of the app if it is currently running on your Mac by using the Quit [App] button in the menu bar. Then open Finder and go to the Applications folder, find the relevant app and drag it to the Trash.
You should check the Application folders for individual users on your Mac. This can be done by navigating from your Hard Drive > Users > [User Name] > Applications.
Empty the Trash, then restart your Mac and download the app again.
Temporarily turn off the firewall on your Mac.
The firewall does a great job of keeping your Mac safe, but it can sometimes get in the way of installing or updating other apps. You can turn it off in the System Preferences, but you should remember to turn it on again after so your Mac is not left vulnerable.
Go to System Preferences > Security & Privacy > Firewall. Click the padlock and enter your administrator password to unlock the settings, then click the Turn Off Firewall button.
You should also turn off any antivirus software, as this may also be interfering with app installations.
After your app installation or update is complete, remember to turn your firewall and antivirus software on again.
Restore your Mac to its factory settings.
This is something of a nuclear option, but it’s there if you want it.
If, after all the other steps listed above, you still can’t get your Mac to install or update apps, a complete factory restore may offer the solution. Doing so will erase all your data and reinstall the macOS, so ensure you have a backup first.
You should also be aware that the entire process can take quite a long time, upwards of six hours depending on your internet speed and how much data you have.
Problems with updating your apps
Recently, Mac users have experienced a new problem in the latest version of macOS Mojave. In this problem, users can’t update their stock apps such as Keynote or Pages. They need to click an accept button in their account, but that accept button doesn’t exist!
This doesn’t happen to everyone: some users can find the accept button without any problems. But if yours is missing, you can still update the app by deleting it from your Mac and downloading a fresh copy from the App Store.
The easiest way to delete an app is to move it to the Trash from the Application folder in Finder. Then it might be worth restarting your Mac before you download the app from the App Store again. And once you do, you’ll have the recently-updated version of it.
How to fix app problems in macOS Catalina
What to do if you can’t approve new apps in macOS Catalina
Another beta problem in macOS Catalina is the inability to approve new apps from the Security & Privacy System Preferences. We explained one way to do this above, but lots of users running the beta version of macOS Catalina have found it doesn’t work.
It seems the solution is to disable Gatekeeper temporarily while you install the new app. We strongly advise you to turn it on again afterward. You can do this by going to System Preferences > Security & Privacy, click to padlock and enter your administrator password to unlock it. Under Allow apps downloaded from: select Anywhere.
If there is no Anywhere option, open Terminal and enter the following command line:
Restart System Preferences and you should see the Anywhere option. You can undo this at any time using the command line:
Make sure you enable Gatekeeper again after installing your app, or you will leave your Mac vulnerable to attack!
What to do if you can’t update or sign in to the Mac App Store
If you’ve been test-driving macOS Catalina through Apple’s Beta Software Program, you might have experienced problems using the App Store on your Mac. Lot’s of users are unable to update or download new apps because the App Store doesn’t let them log in.
Despite entering the correct Apple ID username and password, the Mac App Store still appears as though they aren’t logged in. If this has happened to you, try the following user suggestions to resolve it:
- Sign out of your Apple ID from System Preferences > Apple Account.
- Sign out of Apple Music by going to Account > Sign Out from the menu bar.
- Try downloading the apps or updates from a different user account.
- Update macOS Catalina to the latest beta version, or revert to a stable public release of macOS Mojave.
