Is your Mac crashing regularly? Unexplained kernel panics and/or app quits? Your Mac’s memory might be bad, corrupt or simply poorly seated. Here is how to run a Mac RAM test — quick, easy and the software you need comes built-in!

If your Mac boots from the original hard disk or SSD, and the drive hasn’t been reformatted, restart your Mac, hear the boot chime, then press and hold the D key until…

And, that’s pretty much it (follow the pics). Chances are the Mac RAM test won’t find any problems.

Also, if you Mac’s RAM is poorly installed/seated, it’s possible (though not always practical) to fix yourself (OWC tutorials).
