Mac Pro 5,1 Apple Hardware Test freezes during probe?

[Guest MikeDavies99]

HI all.

I downloaded what should be the correct version of AHT from Github.

Followed their instructions and put it on a USB.

So far so good.

 

AHT boots and starts but freezes during the Probe portion of the test.

The mouse freezes.Other people have had problems with an MS mouse.

Used an Apple mouse.

 

Any ideas? Github shows you a terminal command to return your Board ID.

to identify the correct AHT for your machine.

 

We just did this on my wife's MacBook . Worked fine.

 

Thanks.
