I have the original disks to my Macbook Pro mid-2010. Holding D or option-D at startup launches internet recovery, which ultimately gives error -3403D in both cases. (I was expecting only option-D to launch internet recovery.) The disk does seem to contain the correct AHT version (it is Mac-F22586C8). How can I run the local, non-internet, disk-based Apple Hardware Test?
