EtreCheck

EtreCheck is a system information and troubleshooting utility for macOS that provides detailed diagnostics about your Mac's hardware, software, and security status. It displays information about installed applications, startup items, login hooks, kernel extensions, network configuration, and potential security issues or problematic software. The app is commonly used by Mac support professionals, IT administrators, and advanced users to quickly assess system health, identify conflicts, diagnose performance problems, and verify that a machine is free of malware or potentially unwanted software. It generates a shareable report that can be pasted into support forums or sent to technical support for analysis.
