apple hardware test (AHT) preinstalled on latest macs
it seems that apple ships it's latest mac models, with AHT preinstalled - i.e. if you hold down the 'D' key on startup a new mac boots into AHT even without any CD present.
according to another thread (which i unfortunately lost the link to) it is installed in the following hidden direcotry:
/System/Library/CoreServices/.diagnostics
which contains a whole lot of things.
this is obviously very handy to have, however if you have to do a fresh install this directory does not get recreated, thus we are wondering about the following:
• with which models has apple started to do this;
• does the .diagnostics directory contain model specific information;
• how can we recreate this directory once lost, due to OS reinstallation;
any help appreciated.
