Q: Can't access Apple Diagnostics.
Hoping someone has an idea of what's going on with my machine...
1) I have a late 2013 retina MBP, came loaded with Mavericks as I recall.
2) Did a clean-install upgrade to Yosemite shortly after the OS came out (off of a USB drive). That went uneventfully.
3) I have successfully, several times, run Apple Diagnostics ("D" on startup) in the past, and now can't remember if the last time I did so was under Mavericks, or if I'd ever done it under Yosemite.
4) Lately have noticed my machine "double rebooting" - meaning that when I reboot, I hear a start-up chime twice, and then it goes through the remainder of the boot normally. This caused me to try running Apple Diagnostics. So, pushing D immediately after pushing the power button takes me to a "Starting Internet Recovery. This may take a while." screen, which runs for less than a minute, then sends me to a language selection screen, with "power down" and "restart" selections at the bottom. Choosing English places a check-mark next to the selection, but then nothing else happens. No diagnostic option button appears at the bottom, the screen doesn't change. Nothing. The fan runs harder, so I assume something is making the CPU work harder, but I have no idea what.
5) I then tried doing all the other checks / fixes I could think of - resetting PRAM and SMC, booting into the repair partition and running volume checks and permissions repair on my boot volume, and booting into safe mode, followed by a restart. Trying to get into Apple Diagnostics after all this yielded the same result as before.
I'd love to find an answer that doesn't involve either my reinstalling Yosemite or having to schlep this thing to an Apple store, if possible.
Thanks for any thoughts!
