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

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 [email protected] Please include the full name of the installer, when you downloaded it and the URL of the page you visited to download it from.
