In macOS, if you receive an error message that states: 

"OpenShot Video Editor can't be opened because Apple cannot check it for malicious software."
"This software needs to be updated. Contact the developer for more information."

You can correct this issue. Apple macOS needs permission to run the file you downloaded from the Internet. There are a couple of methods that may work. Follow the instructions below in order until you find the one that works for you:

  2. At the bottom left corner, click the "Lock" icon and enter your password.
  3. Click "Unlock" and then "Open anyway" near the bottom to permit OpenShot to run.
  4. Alternatively, you can select the "Mac App Store and identified developers" radio button and click "Open" on all the listed OpenShot applications.
