I have a late-2010 MacBook Air (11inch, 3,1), running Snow Leopard. I hadn't run software update in a month or two, so I plugged it into the wall and ran software update last night. Unfortunately, the update failed, giving the informative message "An error occurred." Nothing happened for an hour or so after this, so I forced a restart.
Now the MBA won't boot up at all. It hangs on the grey screen, with the little grey wheel spinning forever. I was wondering what additional steps I should take before bringing it in to the apple store? I've already:
- Booted from the provided USB drive and repaired permissions. Permissions repair finds lots of SUID issues it can't repair, but I guess I can ignore these.
- Booted from the provided USB drive and run disk utility. It runs without issues.
- Re-installed Snow Leopard from the USB drive.
- Re-set PRAM
- Re-set the PMC
- Ran the apple hardware test (the short one, not the long one) from the USB drive. Everything passed.
None of these procedures fixed the issue. Ominously, when I try to boot in single user mode, this also fails. It displays lots of errors messages, and never actually gets to a command prompt.
Have there been any recent firmware updates for the 3,1 macbook airs? It doesn't seem to be a software problem, but I'm stumped, and any help is appreciated.
Edit: Here's what the screen looks like:
Edit 2: I did a "Safe Boot" and that appears to hang too. Here's the last few lines of output:
fsck_hfs: Volume is journaled. No checking performed fsck_hfs: Use the -f option to force checking launchctl: Please convert the following to launchd: /etc/mach_init.d/dashboardadvisory.plist systemShutdown false AppleMCP89TMS::powerGatingDown(0): Done
and nothing more for over an hour now.
