27" iMac won't boot properly after power outage

Help! My iMac won’t boot properly following a power outage. I left my iMac in sleep mode and we lost power due to a thunderstorm. When I turned it back on, it chimed, got the Apple logo then white screen with spinning pinwheel (beach ball). I am a freelance videographer and editor, so my computer is my livelihood. Yes, I know, I should have had it plugged into an APC, but I can’t afford to have it repaired professionally and I would appreciate any tips on what could be the problem. Here are the specs of my computer:


27” iMac OS X v. 10.7.5 Lion

2.7 GHz Intel Core i5 Processor

12GB 1333 MHz DDR3


Here are the troubleshooting steps I’ve taken so far:

  1. Rebooted in OS X Recovery mode and ran disk utility, after verifying the disk, it said “The Volume Macintosh HD appears to be OK”
  2. Reset the SMC
  3. Reset the NVRAM
  4. Launched Single User Mode by shutting the iMac down and turning it back on while pressing Command-S. At the command-line prompt, I typed fsck –fy and hit return. After the checks were complete, I got the message that “The Volume appears to by OK”
  5. Launched disk utility again in recovery mode and ran Repair Permissions
  6. Performed a safe boot and it came up fine. Of course, I was unable to connect any peripheral devices to run a quick backups of anything I’ve done since June 2nd, but I’ll deal with that later.
  7. Shut down the computer and left it unplugged from back of iMac and the surge protector for 24 hours. The next day I plugged it back in and just walked away for an hour. When I came back, it was on the login screen. I was so excited that everything was fine. However, it took over 15 minutes to login and once I was logged in, it would take over 30 mins to just open applications, so something is still wrong. It has never run that slow.
  8. The only thing I have not done yet is reinstall Mountain Lion. I’m hesitant in doing that since it runs fine in safe mode. Would the operating system be the problem if it runs fine in safe mode? My last time machine backups was on 2 June, so I’m not too worried about reloaded the OS X and losing data, I just don’t want to take that step if it’s not necessary.


What is a logic board failure? If it fails, would my computer still run in safe mode? Based on the troubleshooting steps I've taken so far and the fact it did start after an hour, but runs too slow to do anything, what could be the problem? I would greatly appreciate any advice or recommendations for this issue. Thanks!

You need to verify that all of your audio related software (of which there is a lo) is up to date. Some items are not (Red entries, see below) but all audio software is suspect (they're usually not quite ready and not good at posting updates.

Ah, but jpfedele is not running Yosemite, they're still on 10.7.5, so it's quite possible that the latest versions won't be compatible anyway. In my opinion he should write a list of the devices and software he needs to run then check with their suppliers to figure out what version of OS X would best suit his needs. Then do a nuke and pave reinstall sticking strictly to the essentials.
