Apple Diagnostics

Another recent discovery was that Apple have changed the traditional Apple Hardware Test for a more modern Apple Diagnostics program

Heres a little checklist for you to check that all your hardware is fully functional

 

If your Mac was released after June 2013, then you will need to run Apple Diagnostics

This is done by holding down D as you power on the machine

 

If your Mac was released before June 2013 and is running 10.7 or newer, then you will access a more traditional Apple Hardware Test

again, this is accessed by holding down D as you power on the machine

 

If your Mac is older, and won’t run 10.7 or above, then buy a new one 🙂

alternatively, Apple Hardware Test should be available on one of the original Mac OS installation disks

you’ve guessed it, insert the disk into the Mac, restart the machine and hold down D to access the Apple Hardware Test

 

If you’ve run the tests and you’ve got an error, then check out the following page for what the error code relates to
