I work in the repair shop as the lead technician at my college and our diagnostic server machine is acting up. Our old Mac Mini ran out of space so we transferred everything to an old stock MacBook Pro that we had. However, it gave us a few issues. The EFI tests in diagnostic mode and AST2 work just fine, but the OS tests freeze the Mac being tested at 'waiting for support'. I believe that this is an issue with Diagnostic Server, as that's where the OS-based tools are loaded from. I've reinstalled Diagnostic Server, its images, and Apple Service Utility. Diagnostic Server log says that everything is up and running just fine. I have tried connecting to our network directly, and also by trying a router with the DHCP server set according to TP567 (except with the router instead of Mac OS Server). Nothing we try seems to work, and it's preventing us from finishing repairs due to the inability to complete the trackpad calibration suite. Has anyone else had this issue?
