Aug 13, 2013  Perhaps you tried to open some application or mount some DMG on your Mac and encountered the following alarming message “Application is damaged and can’t be opened. You should move it to the trash.” Perhaps it is indeed damaged.

• Dmg Damaged Move To Trash Pickup
• Dmg Damaged Move To Trash Truck

1. If you are working on Mac OS X 10.9.2 or newer, you may see a message about a software installer being damaged when you try to launch it. Saying the software 'is damaged and can't be opened. You should eject the disk image' or that the software 'is damaged and can't be opened. You should move it to the Trash.'
2. All downloaded files cannot be opened as they are 'damaged and should be moved to the Trash'. Everything I download will not open. OS X says the file is damaged and can't be opened and should be moved to the Trash. Like Adobe Reader, for PDF documents.

On a Mac, the error message '[Program Name] is damaged and can't be opened. You should move it to the Trash.' means that there's a problem opening a downloading disk image (.dmg) file. There are two usual causes for this problem:

1. The downloaded file is actually broken. We usually only see a corruption of the downloaded installer file when the download was interrupted or if a 'download manager' program was used to download the DMG (as is common in Firefox.) We recommend trying to download the DMG again, using a different browser (like Safari or Google Chrome).

2. Your Mac settings don't allow for software from Apple identified developers. It's common to have your security settings only allow Mac App Store apps. Our software is not in the Mac App Store, but it is signed with our registered Apple Developer identifier certificate (aka an 'identified developer' by Apple.)

   • Open your Mac System Preferences, and select Security & Privacy.
   • Set your 'Allow apps downloaded from' is set to Mac App Store and identified developers.
   • Try opening the DMG again.
   • After opening the DMG and using the program, if you usually prefer to only open apps from Mac App Store, you can set your preference back.

If you're still having issues opening the DMG file, contact us. We'll help get the DMG working, and in case it is actually a broken file on our server, we definitely want to know ASAP! ;)

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.
