Raam thank you for your help to everyone on this.
I have failed to succeed with it though .. on my iMac with 10.6.5 I tried both codes above. I tried the ‘sudo’ code and the ~/library one.
When I ran the sudo one Terminal it asked me for my password which I entered and it returned to admin$ but I then went to check if Google Updater was still in the Applications folder and it was. So I trashed it and rebooted.
The updater just popped up again 🙁
