I have two MacBookPros on which I run 10.6.8. One has a Core i5 (MacBookPro6,1), the other a Core i7 (MacBookPro8,3). I move the SSD from one to other as occasion or whim demands. On the Core i5, AHT runs successfully. On the Core i7, AHT fails to launch. Before the machine shuts down, it briefly displays a window with the error: “Apple Hardware Test had trouble reading env file Configs\AHT_default.env”.
Where is this file located? (note the "\" in the file name). How do I repair it?
