Applies to: macOS 12+ (Monterey, Ventura, Sonoma), Intel and Apple Silicon (M1/M2/M3).
Symptom: When trying to open the installer, you see the popup:
“GoUndetected.dmg is damaged and can’t be opened. You should move it to the Bin.”
Why this happens
macOS Gatekeeper assigns a quarantine attribute to files downloaded from the internet.
If the download was interrupted (by antivirus, proxy, VPN, or browser issues), Gatekeeper may incorrectly flag the .dmg as damaged — even if the file is intact and signed.
Quick fix (recommended)
Re-download the installer only from the official website: goundetected.io.
Open the .dmg and drag GoUndetected.app into your Applications folder.
To launch it for the first time:
In Applications, right-click → Open → Open.
If you see “App was blocked…” in System Settings → Privacy & Security, click Open Anyway.
This gives one-time approval for GoUndetected without lowering overall system security.
Advanced fix (via Terminal)
Use this method only if you downloaded from goundetected.io.
Search for the terminal:
Remove the quarantine attribute from the installer:
xattr -dr com.apple.quarantine ~/Downloads/GoUndetected*.dmg
Make sure, that you selected correct path to file and correct file name.
The issue won't exist anymore on your Macos
