Apple Diagnostic Test runs instead of Apple Hardware Test
I have a Mid-2012 MacBook Pro running Mojave. I decided to run Apple Hardware Test to check if anything's wrong, the machine is 7 years old now after all.
To my surprise, I see Apple Diagnostic Test running on my screen.
I thought it was only available on Macs from a time after June 2013?
Could somebody explain why I have access to Apple Diagnostic Test?
