prebinding update

I am using a MacBookPro running OSX 10.6.4
When I am optimizing the system using Onyx I receive a message half way through the process saying:

/bin/sh:update_prebinding not found

Should I be concerned? What does it mean?

G'day and welcome to the forums.

First question have you updated to Onyx version 2.1.8 for Snow Leopard? This may help:-

Will do

Thanks mate, I haven't and I will and see what happens
