Q: Restarting continuously: Apple iMac Core 2 Duo 3.06 24-Inch (Early 2008). MB398LL/A A1225 (EMC 2211) Model ID:iMac8,1. O.S: Mavericks

Hola, Good afternoon,

this is my first issue with a Mac i couldn´t fix by myself.

I have checked dimilar issues on different apple forums and different possible things to test but no apparent solution.

As alwasy i would like to fix it myself to have a control of the computer.

Backups are done. and also a bootable USB with mavericks but no luck.

 

System:

Apple iMac Core 2 Duo 3.06 24-Inch (Early 2008).

MB398LL/A A1225 (EMC 2211)

Model ID:iMac8,1

O.S: Mavericks.

 

Problem: The computer turned off last week while i was writing and now everytime it starts, goes into a loop: keep on restarting as follows: Apple logo icon, time circle, restart—> Apple logo icon, time circle, restart ...

 

I can listen/see the following:

•Startup chime.

•Fan & drive operation noises.

•Pressing the Caps Lock key on the keyboard causes it to light.

• Apple logo icon, time circle, restart (in loop) —> Apple logo icon, time circle, restart —> Apple logo icon, time circle, restart.

 

Power issues

•Verified a good connection from iMac to the wall

•Disconnected all accessories that are plugged in to computer.

•Holded down the power button for ten seconds.

•Reset the SMC.

•PRAM

 

I can´t access Safe Boot (Shift ⇧ Start up in Safe Mode) or disk utility. The computer after a long time after apple logo goes into the time circle and after 15mins turns the screen off and does not go to any point. I let it like this, all night long and also no success.

 

But, I can access Single User mode (Command-S) and made next steps:

  1. fsck –fy and press return
  2. mount –uw and press return
  3. touch /private/var/db/.AppleSetupDone and press return
  4. Type exit and press return

But also no Luck...
