System not booting up after OS X Update 10.8.5

by tyro1989 / September 13, 2013 10:20 PM PDT

Hi All,

I am new to MAC (and also to forum).

Yesterday, I updated my OS to 10.8.5 and I am unable to boot it again.

On boot up, it shows some error kind of black screen with some message:

A part of which is:
"Kernel extensions in backtrace:"

Then it shows message saying

"Your system was restarted because of some error. Press a key or wait a few seconds to continue starting up". After this message, it again goes to login interface again.

I tried to restart multiple times but it doesn't help.

I can start in safe mode but functionalities are very limited and I am not able to work.

I found that we cannot roll back to a previous version. My time machine was not enabled till now. I connected a HDD but it is not detected so unable to do anything.

Please provide the steps I should take. Please provide low level details, if possible as I am quite new to MAC.

I solved the problem folks.

NoMachine version was not compatible with the MAC OSX 10.8.5.

Restarted in safe mode, removed no machine and it worked Happy
