Thunderbolt Firmware Update 1.2 / Thunderbolt: No hardware was found.

We purchased a 2012 27" iMac at work which I connected to a 23" cinema display via a MDP->DVI adapter. It worked for a while, but then stopped working 1 day. Thinking it was the monitor or the adapter, I connected a 27" cinema display with a direct MDP connection - still didn't work.


After doing the typical SMC/PRAM reset, I noticed that in System Information under thunderbolt it said "Thunderbolt: No hardware was found." I also noticed that the App Store listed a Thunderbolt Firmware Update 1.2. So, I updated that, restarted, it flashed the progress bar for a second but didn't move before restarting again and booting. The firmware update was still listed in the app store. I tried downloading the DMG for the update on the Apple Download site, install seemed to go well, but did not install.


Then I found this: http://support.apple.com/kb/TS4579. I ran through that process (also reset SMC/PRAM again). Still no go. After calling Apple support, they recommended that I reinstall OS X. Still didn't work after that. I called back today, and apparently my only option is to carry it to the closest Apple Store, which is an hour and a half away (we have a closer authorized dealer, but they are closed until July 8th for some reason). I also asked if they could send a box so I could ship it and they said that wasn't an option.


Is there anything else I can do without having to wait until July 8? I am extremely disappointed with Apple right now, and I'm hoping I can get this resolved without having to run all over the place.

iMac, OS X Mountain Lion (10.8.4)

It sounds to me that you've gone through all the possibilities as regards software and that your iMac has a hardware issue. If so, then taking it to an Apple Store or authorized Apple service provider is going to be necessary. Apple typically does not provide ship-in service when they have authorized service in your area. You'll either have to wait for the service center to re-open on the 8th or drive to the Apple Store.

Hi - have anyone helped you with this issue?

I have the same challenge and I wonder what the next step to take before going to the store.


I appears to be software issue, as it happens to many of us, so there must be an answer to this and a fix that saves the trip to the Apple center. Apple store visit would address hardware failure, which this appear not to be, unless Software update pushed by Apple caused this hardware to get lost.


HELP ANYONE...!?
