Invoked by apple software

I have an iMac, early 2008, with 6 GB RAM.
Two days ago I upgraded to Mavicks.
Today I cannot use my computer. I get the following message.
Unapproved Caller
Security Agent may only be invoked by Apple Software

I have booted in all possible modes, I have repaired disk permissions, I have verified the internal hard disk. All the above multiple times. I have unplugged for 15 seconds, plugged for 5 and booted. I a have tried all that I know and a few things I did not know.
All to no avail, the problem remains.
HELP!

Thanks

Exactly the same happened to me last week, a trip to the Apple store and a new flat hard drive cable sorted the problem.

Not an option for me.
I live in Cancun.
Closest Apple Retail Store is in Miami.
Thanks anyway.

I have a progress report (with no much progress).
After some more frustration in front of my iMac trying things I was able to connect to Internet and run a new Mavericks install. This was done by booting with Cmd-R.

The process took most of the night and this morning it was finished.
But I still have Finder freezing after a while; pages, numbers and such freezing before opening.

So, frustration keeps growing and I keep trying... but I am lost.

Thanks for your help.

The hard drive and/or cable could be failing. I would make sure any important data is backed up and either find an authorized repair center near you or see if you feel comfortable opening up your iMac, instructions here.

Fix for Unapproved Caller

Hello,

The problem you are experiencing is a bad clean up job after an OS upgrade. When upgrading from 10.9 to either 10.9.1 or 10.9.2, the installer is supposed to delete/remove files from the "/var/folders/" directory. This fails which causes faulty requests for elevated privileges in different areas of the OS.

To fix this issue, simply remove the caches in the "/var/folders" directory by running the command below:

sudo rm -rf /var/folders/*

Let me know if this worked out for you.

Thanks,
Abraham
