How to Check a Mac's S.M.A.R.T. Status

S.M.A.R.T. stands for Self-Monitoring, Analysis and Reporting Technology, and it verifies the status of your Mac's hard drive. The S.M.A.R.T. status of your Mac can be found in two ways -- either through the System Report window or through your system's Disk Utility. Use the status reading as a way to determine whether your hard drive needs repairing or replacing.

Verified Status

A S.M.A.R.T status that reads "Verified" indicates that your hard drive is functioning normally. Continue to use your device as usual; no further action needs to be taken.

Failing Status

A failing S.M.A.R.T status indicates that the hard drive is faulty or dying. This can be caused by an old hard drive or corrupted files on the device. Take the computer to an Apple Store or an authorized Apple service provider for assistance with fixing or replacing the hard drive.
