“OwlPlug” is damaged and can’t be opened.

Fresh downloaded file doesn't open. Running xattr -cr on the app in terminal fixes the issue, however.

This is in macOS 10.13.6, not sure if it affects other versions.

Hi @CrimsonFlash. I agree, this is a really annoying error and it's not anymore scoped to macOS Catalina only... The solution I found is to notarize the app by joining the Apple developer program. Unfortunately, It's not really affordable for me now 😢 (see #31)

The app is not notarized by Apple and flagged as downloaded from the internet (MacOs put it in quarantine).
You can fix this by following a simple procedure described here: https://github.com/DropSnorz/OwlPlug/wiki/Troubleshooting

sudo xattr -rd com.apple.quarantine /Applications/OwlPlug.app/

Hope it helps 🙂

From #194

I have reports from macOS Ventura users about restrictions far heavier for non-notarized app. The procedure seems to be the following for Ventura (but needs confirmation)

• Attempting to run OwlPlug may show a window explaining it cannot be opened because "Apple cannot check it for malicious software." Click Ok.
• Open System Preferences and select Security & Privacy.
• If the padlock in the bottom left is locked, click it and authenticate to unlock it.
• Next to the message explaining the app "was blocked from use because it is not from an identified developer," click Open >Anyway.
• Close System Preferences.
• Run the app.
• A notice will reiterate the warning about an inability to check if it is malicious each time you run the app. Click Open.

Reopening this issue. Based on user feedback, things seems different for Sonoma.
