Troubleshooting a troublesome Mac isn’t as difficult if you know the first step. It may be easier than trying to figure out what’s gone wonky in a Windows or Linux PC but you have to follow the steps. Here is step one.
Mac users have a few utilities that can help out a tech support guru or Mac genius to solve whatever ails yours Mac. It starts with a free utility which gathers information about your Mac and its system configuration. That makes it perfect for sharing via email, or copying to an Apple Support Community thread for help.
What’s Your Mac Running?
Every now and then, especially before and after I update OS X to a new version, install a new app, or upgrade any app or utility, I’ll run EtreCheck. It’s a free utility that captures your Mac’s system configuration, and it’s as simple to use as a double-click in the Applications folder or a click in the Dock.
All EtreCheck does is scan your Mac’s system and capture as much information about the hardware and software as possible. For security and privacy reasons, EtreCheck then removes any information that could personally identify you. It won’t ask for a password, either. It’s just reading and gathering data that is available on your Mac, but not personally identifiable.
First, EtreCheck checks your Mac’s hardware. Then it steps up the game and checks the Mac’s software. All of it.
When it’s done with the initial scan, EtreCheck displays a very long list of your Mac’s hardware and software setup.
Far more detail than you’ll get is the Mac’s standard About This Mac System Report.
The real value to EtreCheck’s system configuration check is when you can share it with tech support, Apple Support Communities, even Apple’s own Genius Bar (but if you’ve noticed, Genius Bar techs run their own series of complex diagnostics). I run EtreCheck before and after every macOS update, and save a copy. If your Mac won’t start up, all that system configuration information can come in handy to a tech support rep.

And more, of course, so what’s not to like? EtreCheck is free. The best time to take a system snapshot is just before upgrading apps or changing software or settings. Then, if something goes wrong, there’s a side-by-side comparison option to check through; and tech support people love it.
