Discover App Quarantine, the macOS feature that scans and quarantines downloaded apps and files to safeguard your Mac against malware threats.
App Quarantine is a security feature in macOS that monitors apps and files downloaded from the internet to prevent malware. When an app or file is downloaded, App Quarantine will check it against a database of known malware and threats before allowing it to run. If the app or file is deemed unsafe or is from an unverified developer, App Quarantine will quarantine it - this restricts its abilities to access files and make changes to your system.
App Quarantine works automatically in the background. When you try to open a quarantined app, you'll see a warning dialog indicating that the app was downloaded from the internet. You can choose to open the app anyway, but this is not recommended for apps from unknown or untrusted sources. App Quarantine reduces the risk of downloading and running malware, spyware, and adware on your Mac.
Overall, App Quarantine provides an important layer of protection against threats from downloaded apps and files. It prevents potentially dangerous apps from instantly gaining access and making changes. While not a comprehensive anti-malware solution, App Quarantine does limit the damage malware can do if downloaded accidentally while browsing the web or installing software.
