Why?

Your macOS system includes a security feature, called Gatekeeper, that can block the installation of applications downloaded from sources other than the Mac App Store or from a list of “identified developers”. This is to prevent you from installing “malware” – malicious software on your Mac.

If you run into this issue meaning if you see the “damaged” label, it is highly likely that the app you are trying to download has been altered by something other than the developer. It is also mean that the app you want to install is from an identified developer. So your Mac is trying yo warn you. You may think that the app is developed by a trusted source. However make sure that you are downloading the app directly from the developer website only. Do not use a third party source. If you still think, the app will not hurt your Mac upon installing, please read how you can install it below:

How

1-You may want to re-download the app. It is possible that the app might be damaged during the downloading process. Also, please make sure that you download directly from the developers website. As stated above, do now download from any other source. For instance, do not download the Google Chrome app from any other source than Google itself.

2-It is known that sometimes macOS gives this error mistakenly. Sometimes installing some trusted apps may be prevented. You may want to simply restart your Mac. And further, on your Mac, go to System Preferences > Software Update and check to see if there is an update available.

3-You may want to temporarily disable Gatekeeper. This was easy but newer version of macOS do not have the option of changing this easily by going to System Preferences > Security & Privacy and selecting the Anywhere option. However you can still do that using the Terminal app. Here is how:

1. Launch the Terminal app (Applications > Utilities), you may also use Spotlight to search and launch it. (Spotlight not working?)
2. Enter the following and hit enter
3. sudo spctl –master-disable
4. You will have to enter your password
5. And you are done. Now you can install and open apps from unidentified developers.

If you want to disable this option after you are done, here is how you can do that:

1. Open the Terminal app
2. This time enter the following command hit enter
3. sudo spctl –master-enable
4. Enter your password and you are done

You can also disable this by going to System Preferences > Security & Privacy on your Mac. Simply select the “App Store” option or “App Store and Identified Developers” option. However, a few users have reported that even changing this setting does not stick meaning does not work. So you may have to do this via Terminal as explained above.

Mac OS X security by default does not allow all .app extensions to be installed. At worst, it will throw an error message that the app “is damaged and can’t be opened.” This error makes you believe that the downloaded app is corrupted and that there is no application that could let it open. However, sometimes this is just a security issue that can be corrected.

Users are seeing warning messages about downloaded applications being damaged and unable to be opened. Sometimes is due to a true corruption during download. These days download corruption is very rare, and more frequently this is a due to Apple’s increasing security measures. If you are trying to open an application that did not install through the Apple App Store, you likely just need to adjust your security preferences.

Open Applications Downloaded from the Internet

1.Go to the Apple icon, and chose System Preferences.

2.Under System Preferences, choose Security & Privacy.

3.Choose the General tab. By default, Mac OS X security allows only the apps that are downloaded from the Mac App Store (such as iTunes) or from Mac certified developers. Although it is safe to install apps that Apple recommends, there are always scenarios in which you will need to download .app files from the Internet.

4.To fix the “Move to Trash” error, we need to change the Allow apps downloaded from: option to Anywhere. You cannot do that since it is grayed out and disabled. It needs authentication from an administrator. To do that, click on the lock icon next to Click the lock to make changes. That should open a dialog box asking you to enter your password. If you have not set your password, just leave it blank, and hit the Enter key on your keyboard.

5.Now, select the Anywhere radio button. Once you choose that, it should open up another dialog box as seen below. Just chose Allow From Anywhere. Now, you can simply close all the windows, and Mac will automatically lock Security & Privacy for you.

6.Open the .app file that you want to be installed. Instead of the error message, now it will give you a warning telling you that this app is downloaded from the internet and asking would you still like to open it. If you are sure about what you are installing, just click Open, and it should let you install it without any error.
