Hi Vince, I tried googling, but I could not find anything (at least not yet) about any of this.
The only thing I found was stuff about Applejack, which will allow diagnostics from single user mode, but it has to be already installed on the boot drive. A friend long ago told me to install this, but apparently I forgot, as I get a message saying the command is not recognized :( Gregg On Oct 30, 2011, at 6:01 PM, Vince LaMonica wrote: > On Oct 30, 2011, at 5:54 PM, Gregg Dinse wrote: > >> Hi Vince, >> >> As I wrote a few minutes ago, I tried holding down the "D" key while >> booting, but it had no effect, so I guess my system does not have the >> hardware test built-in (or it is too messed up to get to it). >> >> I guess the next step is to either take the iMac to a repair shop or to try >> inserting the hardware diagnostic DVD.
