App Store said there was a Yosemite update.
I restarted it and during the update, the power to the neighborhood went out. This particular computer was not on a backup battery so it shut down.
Now, when I boot up, I get a progress bar and then it shuts down.
I held down D on book and ran that test but it didn't say anything.
It just keeps shutting down so I need some advice.
Attempt to do a PRAM reset and see if it launches. Click iMac SMC and PRAM reset for instructions. If it will not start up, then start in the Recovery Partition (Command + R) and open Disk Utility and run Repair Disk 2-3 times. If errors appear after the 2nd or 3rd attempt that mean the HD is damaged and must be replaced. If no errors appear, then quit DU an re-install OS X and attempt to update again. However I would STRONGLY consider getting a UPS for just this reason, power surges and sudden losses of power can be devastating to computers.
Please post back if you continue to have problems.
I reset Pram to no avail.
I ran the Disk Utility several times. Nothing doing there either.
Same issue as before however. Boots, progress bar, shuts down.
Any other ideas? I can take it to the Apple Store if I must...
When in the Recovery Partition - Disk Utility, does the internal HD show up?
YUp. I couldn't run the Disk Utility if it didn't, right?
