Q: Because of slow iMac boot-up, NVRAM reset, now grey screen, stuck!
Hi,
because of an ongoing slow boot-up sequence on my iMac (27", Mid 2011, Intel-based) I did an NVRAM reset successfully. Immediately during the next startup my iMac hung in the grey screen and is not booting at all since then, no apple logo, nothing, just the turn-on sound.
I tried to boot into recovery mode successfully once, did nothing there and since then I had no luck with any boot-up keyboard shortcuts.
I may have to mention, that I did manually upgrade my system with an ssd in addition to the hdd and created a fusion drive a couple month ago. All worked fine so far. Don't know wether this plays a role in regards to the keyboard shortcuts.
I also experienced bootup failures (system beeping) from time to time (very seldom). Typically it was sufficient to take off power and reattach it, afterwards the system was booting fine.
Does anyone has any idea what to do!?
Regards,
Starbug
