"pc needs to be rebooted. press and hold power button untill pc shuts down then repress power button"

Which OS version did you install? All updates are safe, except OS X update, which is potentially problematic.

 

For example, updating from 10.6.3 to 10.6.8 or 10.7.3 to 10.7.4/5 without precaution usually results in systematic KP at reboot. On the other hand, it's usually pretty safe to update from early 10.6 to 10.6.7, from 10.7.4 to 10.7.5 or 10.8 to any subsequent versions.

 

What we always recommend is:

1) never us Apple-menu/auto OS X updates but download Combo updates off Apple's web site

2) after combo update execution, do not reboot but re-run EDP kext installation, then reboot

10.6.1? That's not a retail version... How do you install OS X???

 

Yes, you can install all the other updates, except OS X 10.6.8. For that specific update, download the Combo update, run it BUT before rebooting like specified upon execution, re-run EDP and proceed with kext installation again. then it's safe to reboot into 10.6.8.

Mmm, sounds like a well-known distro, you might not be 100% kosher and EDP-compatible... Only 10.6.0 and 10.6.3 are retail versions. I guess newest Apple 10.6.8 SL offering should be too.

 

To get OS X version, do Apple Menu-> About this Mac
