billjobs Posted November 4, 2009 Share Posted November 4, 2009 Hello, first I would to apologize for my bad english... There is my problem : I have a macbook mid 2007 with broken display and maybe other bad issues (fan, sensor, superdrive,...) ???? the macbook goes on and boot and I can use an external display, but I would to run AHT on it for testing the machine and when I boot in target disk mode (the superdrive is KO) with the "D" key I don't see anything on external display even in clamshell mode, I think because I boot with the AHT on DVD an this is a "basic" system. My question : it is possible to modify the EFI for than the macbook boot the external display like the main screen or it is possible to modify the AHT for booting on external display thanks for your answers...
