EtreCheck

About

EtreCheck is a free Mac app that helps you diagnose problems. You pick a problem, enter a description, and start a report. The app runs for about three minutes, then points out major and minor problems. It can also help you fix security settings, find and remove malware, and find and fix storage problems. If you need more help, you can share your report on the internet.

If you don't want to post anything online, EtreCheck offers computer-generated Solutions. The optional Power User package is a one-time, single-purchase upgrade, not a subscription. It provides detailed results and supporting information about hardware, operating system, storage, networking, software, and performance. It also includes deeper analytics and lets you compare your computer and your report to others.

EtreCheck is available as a free download, and the website offers system requirements, installation instructions, and a FAQ with tips for keeping a Mac healthy.
