How to Verify Your Mac’s Hardware Is Working Properly | The Mac Security Blog
Your computer consists of both hardware and software. In this 2-part series, we'll take a look at how to check your Mac's hardware and software to verify your system is in good shape or if certain components are failing. In part 1 below, you'll learn how to check and verify your Mac's hardware is working properly. Stay tuned for part 2!
I get asked all the time how to solve issues on a Mac, but rarely do I get asked how to simply verify a Mac's hardware is in good shape even when it's not experiencing issues. Not many people check their systems when everything is working properly, it's usually when an issue arises folks start troubleshooting—and by then it could be too late.
Think your Mac's hard drive is failing? Want to determine which hardware component is failing? In this article, I'll list some of the ways you can check your Mac to make sure everything is working the way it should. After all, just because everything seems to be running smoothly right now does not necessarily mean everything is actually OK.
NOTE: Checking a system in most cases requires it to be put through the wringer. This can stress out and break components that may already be failing. Make sure you have one or more backups of all your data and proceed at your own risk!
There's quite a lot to cover here, so if you'd rather skip to the hardware you want to test, click on the appropriate section below.
