Troubleshooting Mac: How to Fix ‘App is Damaged and Can’t Be Opened’ Issue

Hey there!

Ever encounter that nerve-wracking message telling you, “Your application is damaged and can’t be opened!” on your Mac? Truly a frustrating experience, isn’t it? Don’t worry, I’ve been there before, and I’m here now to help you sort it out.

Let’s Roll Up Our Sleeves and Fix This!

Your Mac is known to have a strict Gatekeeper feature designed for your protection, and sometimes it gets a little TOO overprotective. Here’s a quick rundown of how we can bypass this blockade.

To commence, launch Terminal by searching for it in Spotlight or by locating it in the Utilities folder under Applications. Then, copy and paste the specific command below, hitting Enter afterwards.

sudo xattr -r -d com.apple.quarantine /Applications/[app name]

Note: Replace [app name] with the actual name of your application. Remember to keep the .app at the end and ensure there are no errors. This command serves to remove the erroneous ‘quarantine’ attribute that’s causing the whole ruckus.

MacOS Insider Tips

  1. If an app gives you trouble even after trying the above steps, try this alternative command instead:
sudo spctl --master-disable

This command turns off Gatekeeper completely, thereby allowing the application to open. Make sure you turn it back on afterwards with this switch-flipper:

sudo spctl --master-enable

Never forget the importance of security. You don’t want to leave your Mac defenseless!

  1. Make it a rule of thumb to always download applications from trusted sources. While Apple’s security measures can be strict, they’re in place for a reason.

Moving Forward

Is this solution worth it? I’d say yes, with an asterisk. If you’re certain that your app comes from a trusted source, and you’ve double-checked everything, it’s usually quite safe to override Gatekeeper.

I’ve used these steps multiple times and they never fail to bail me out of the ‘App is Damaged’ blues. As for alternatives, you could always delete and reinstall the problematic app or even restart your Mac – these simple steps surprisingly solve a lot of issues.

Next time, I’d be a lot more cautious about where my apps come from, and try to stick to the App Store where possible. But if not, I now know the Terminal is my friend and won’t hesitate to use it.

Hopefully, this helps you out in dealing with this common Mac roadblock. Remember, there’s always a solution with a dose of patience, some Google-fu, and a handy Terminal command. Let’s keep exploring and troubleshooting together!

Happy fixing!
