1. Mac Os Sierra Damaged And Can't Be Opened
2. Mac App Is Damaged And Cannot Be Opened Sierra Madre

While the secure options were good ideas for less experienced Mac users, power users found Gatekeeper to be too limiting and typically sought to disable it by setting it to “Anywhere.“ In macOS Sierra, however, the “Anywhere” option is gone, leaving “App Store” and “App Store and identified developers” as the only two options. If you have updated to macOS Sierra and get a ‘Damaged and can’t be opened’ error when trying to launch an app, you should make sure that the app has been updated to the latest version. If the issue still persists after updating the app to the latest version, remove it from your Mac and install it again. As mentioned earlier, if you are seeing a similar error with a Mac App Store app saying “Name.app is damaged and can’t be opened. Delete Name.app and download it again from the App Store.” then click here for different instructions at resolving. Usually you simply have to log back into the Mac App Store and re-download the app in that situation.

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. e.g. 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.'

Newer Mac systems include a security setting that can block the installation of apps downloaded from places other than the Mac App Store. To install QIAGEN software, you need to allow apps downloaded from identified developers as well the Mac App Store. Do this by adjusting your security settings:

1. Go to System Preferences | Security & Privacy
   
2. Click on the padlock icon at the lower-left corner to enable you to make changes.
   
3. Choose 'App Store and identified developers'

We sign our software with a Developer ID from Apple. With the above setting chosen, you should be able to install our software. You will see a message warning you that the software has been downloaded from the internet, and asking if you wish to open it. This is expected, and you can proceed with installing the software.

Security settings affect your whole system. If you generally do not want to allow apps downloaded from anywhere except the App Store, then change the security settings back to the desired setting after you have finished installing your QIAGEN software.

If you continue to see this issue with the 'Allow apps downloaded from' option set to 'App Store and identified developers', please report this problem by emailing AdvancedGenomicsSupport@qiagen.com Please include the full name of the installer, when you downloaded it and the URL of the page you visited to download it from.

If you wish to proceed with installation anyway

If you are certain you obtained the installer via official channels and thus wish to proceed with installation anyway, information on how to do so is below.

Mac OS X 10.9.2 to 10.11.x

In Mac OS X 10.9.2 and newer, there is a security setting that must be changed so that the downloaded installer can be opened. To change this setting on Mac 10.9.2 through 10.11.x, please take the following steps:

1. Go to System Preferences | Security & Privacy
   
   
2. Click on the padlock icon at the lower-left corner to to enable you to make changes.
   
3. Select the option for Allow apps downloaded from: to Anywhere
   
   
4. Close the security settings window
   
5. Double click on the installer file again and click the Open button when prompted.
   

We recommend reverting your security settings after installation of the software is complete.

Mac OS Sierra 10.12.x

The premise is the same as shown for Mac OS 10.9.2 through 10.11.x except that the steps to enable the 'Anywhere' option are different.

If you view your security settings under System Preferences | Security & Privacy, you will see there is no Anywhere option.

To enable the 'Anywhere' option, run the following command in a terminal:

If you go back to System Preferences | Security & Privacy, you will see the Anywhere option enabled. Unlock the edit option by clicking on the padlock icon at the bottom of the window to change to Anywhere option.

At this point, you should be able to install the software.

This security setting affects your whole system. To reinstate the earlier security policy, run the following after the software is installed:

and then check your security settings are as you expect.
