Q: Imac diagnostics will not start in Mavericks
Hard drive is clicking at start up sometimes and when I come back to my Mac after it goes to sleep, sometimes I can't get a login screen. I have to manually reboot at times.
OS 10.9.5 Mavericks
Processor 2.66 GHz Intel Core I5
Memory 4 GB 1067 MHz DDR3
I'm thinking hard drive failure but can't get to the hardware diagnostics at start up.
Any help greatly appreciated.

Is there anything in the folder /System/Library/CoreServices/.diagnostics
If you have the Apple Diagnostics installed there should be two folders and a diags.efi file I think - the names of the folders depends on your hardware. If you don't have the Apple Diagnostics you MIGHT find a copy at https://github.com/upekkha/AppleHardwareTest (not all systems but many)
Good luck
