How to: MacBook Pro Diagnostics

By Jedadiah Casey

MacBook Pro laptops are produced by Apple and are designed for professional and enthusiast users due to their higher specifications and higher retail price. MacBook Pro computers are similar to other computers in that their internal components can stop working properly over time. Testing the components by performing a hardware diagnostic is the best way to determine if a component, such as memory, needs to be replaced. You can perform diagnostics on the MacBook Pro laptop by running the included Apple Hardware Test suite.

Step 1

Insert the disc containing the Apple Hardware Test suite into the disc drive, then restart the computer. For MacBook Pros that shipped with Mac OS X 10.5.4 or earlier, insert disc 1. For MacBook Pros that shipped with 10.5.5 or later, insert disc 2.

Step 2

Press and hold the "D" key until the MacBook Pro begins to boot from the disc.

Step 3

Click to select your language, then click the right "next" arrow.

Step 4

Press the "Return" key to perform the basic hardware diagnostic tests. If no errors are found, proceed with the next step.

Step 5

Click to place a check in the "Perform extended testing" box, then click the "Test" button again. If any errors are found, they are displayed in the console window.

Tips & Warnings

  • Extended tests take much more time to perform than basic tests.
