EtreCheck

EtreCheck scans a macOS system and generates a report that highlights major and minor issues across hardware, the operating system, storage, networking, installed software, and overall performance. The utility identifies security problems, such as malware, and provides guidance for fixing security settings. It also pinpoints storage‑related concerns, offering recommendations to resolve “System Data” or other storage anomalies.

Users can run the tool, wait a few minutes for the analysis, and then review detailed results that include supporting information and analytics. The report can be shared online for additional assistance, or kept private with computer‑generated solutions for users who prefer not to post data.

A paid Power User package is available as a one‑time upgrade, adding features such as deeper analytics, comparison of the current report with others, and the option to view detailed hardware and software information without an internet connection. The software is stable and targeted at macOS users who need to diagnose and remediate system problems.
