Step 1:Locate the "Cheating Dev.app" file in your Downloads folder (or wherever you saved it)
Step 2:Right-click (or Control+Click) on the app icon
Step 3:Select "Open" from the context menu
Step 4:When macOS shows a warning dialog, click "Open" again
Done!The app will open and macOS will remember this permission for future launches
2
Terminal Method (Advanced)
Open Terminal and run this command to remove the quarantine attribute:
Terminal — -zsh
$If app is in Applications folder:
xattr -cr "/Applications/Cheating Dev.app"
$If app is in Downloads folder:
xattr -cr ~/Downloads/"Cheating Dev.app"
▶Click copy icon or press Enter after pasting
Note:Replace the path with wherever your app is located.
Result:You can now double-click the app normally without the error.
Why Does This Happen?
• macOS Gatekeeper is a security feature that temporarily blocks downloaded apps
• When you download an app, macOS adds a "quarantine" attribute to it
• The app isn't actually damaged - this is just a security precaution
• Both methods above safely remove this restriction
