Sep 11, 2015  I've downloaded Xcode 7 beta, mounted the dmg, and copied it to Applications. When I attempt to run, I get this alert: “Xcode-beta” is damaged and can’t be opened. You should move it to the Trash. So I trash the app and the dmg, then repeat. I've done this maybe 5 times now and it never does work. How can I resolve this? I'm running 10.11. We are experiencing a problem with flash projector.app executables that we build. When the app is downloaded from the internet on OSX sierra the message 'XXX can't be opened. You should move it to trash.' Clicking on the help icon next to it additionally displays the info. Sometimes when you download and app for your Mac from the internet you unpack it and maybe get a disk image (DMG) and inside it there’s the app that you drag & drop into your Applications folder. But when you doubleclick the app it doesn’t launch. Is damaged and can’t be opened“. Nov 03, 2017 The dmg in local can be opened and the app is also can be opened, but when i upload the dmg to server (such as S3, Akamai) and then download it, the dmg can be opened but the app cannot be opened, it says 'is damaged and can’t be opened.You should eject the disk image.'

Fix damaged file. To solve ‘this app is damaged’ error, simply open Terminal from Launchpad and enter the following command. Sudo spctl -master-disable Enter your password and you’re done.

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.
