Protecting Your Mac

Understanding system information can help you keep your Mac safe and secure. By using the System Information app, you can identify potential security issues like outdated software or firmware, as well as hardware vulnerabilities.

To keep your Mac secure, stay up-to-date with software updates and security patches. Avoid installing software from untrusted sources and use a reputable antivirus program to scan your device for malware.

Using System Information to Diagnose Performance Issues

System information can be used to diagnose specific performance issues on your Mac. For example, if your device is running slowly, you can check the Activity Monitor to see which processes are using the most CPU or memory. You can then end those processes to free up resources.

Another common performance issue is a lack of storage space. If your Mac’s storage is nearly full, you may experience slow performance or other issues. By using the System Information app to identify which files and applications are taking up the most space, you can delete them to free up storage and improve performance.
