Title
👉 Overview
👀 What ?
GateKeeper is a security feature of the MacOS operating system by Apple. It enforces code signing and verifies downloaded applications before allowing them to run, thereby reducing the likelihood of inadvertently executing malware. Disabling GateKeeper might be necessary in some situations, for instance, when installing certain software not from the App Store.
🧐 Why ?
Understanding the function and potential risks of disabling GateKeeper is crucial for all MacOS users. It is a fundamental aspect of MacOS security and helps to protect the system and data from malicious software. However, there might be instances when GateKeeper prevents the installation of legitimate software, hence knowing how to temporarily disable it can be beneficial.
⛏️ How ?
To disable GateKeeper, open Terminal and type 'sudo spctl --master-disable'. This command requires administrator privileges. After executing the command, you will be able to install applications from any source. To re-enable GateKeeper, use the command 'sudo spctl --master-enable'. It is advisable to keep GateKeeper enabled whenever possible to maintain system security.
⏳ When ?
GateKeeper was first introduced in MacOS Mountain Lion in 2012. It's important to remember that disabling GateKeeper should be a temporary measure during the installation of trusted software and should be re-enabled as soon as the task is complete.
⚙️ Technical Explanations
GateKeeper is a layer of security that uses XProtect to scan downloaded applications for known malware. It also checks if the software comes from a recognized developer or the App Store. By default, MacOS only allows software installations from these two sources to protect users from potentially harmful software. Disabling GateKeeper stops these security checks, allowing applications from any source to be installed. This could potentially expose the system to malware if the source is not trustworthy. Therefore, users should only disable GateKeeper if necessary and only for a short time.
