EtreCheck is a program that was designed to help you find and share information about the current state of your system. The application is very simple to handle, provides you with a complete report, offers you useful instructions, and comes without a price.
The first thing you need to do before letting the app analyze your system is to provide a reason for using the program on your Mac. For example, you can use the app is you notice that your Mac is running slow. You can also attach other reasons if needed. Afterwards, the app will start scanning your system and reveal a detailed report. You can print or share the offered details directly from the program's interface. Furthermore, the app lets you copy info from the report to your clipboard.
EtreCheck also provides you with plenty of useful instructions regarding each report category, a feature which might prove to be of good use to beginner Mac users.
My only problem with this app is that it might take a while to complete the scanning process. Still, it's definitely worth the wait as the reports are accurate and comprehensive.
In conclusion, I'd say should install this program on your Mac if you want to easily learn info about the current health state of your system.
