Hi tim,
My Post Title Should Read "SOLVED:Ticking Auto Proxy Discovery in 10.6.X"

My post is putting a tick within the "Auto Proxy Discovery".
The below and above script does this.

#!/bin/bash

# Mac OS X 10.6.X
# Date: 09/2012
# Author: Isaac Bayssari

# This will tick the auto proxy discovery tick box for 10.6.X machines.

echo "list Setup:/Network/Service/[^/]+/Proxies" | scutil | awk '{print $4}' | cut -c 24-59 | while read serviceid; do /usr/libexec/PlistBuddy -c "Add :NetworkServices:$serviceid:Proxies:ProxyAutoDiscoveryEnable integer 1" /Library/Preferences/SystemConfiguration/preferences.plist ;/usr/libexec/PlistBuddy -c "Set :NetworkServices:$serviceid:Proxies:ProxyAutoDiscoveryEnable 1" /Library/Preferences/SystemConfiguration/preferences.plist; done

Please email me if you would like a copy of this script.

Thanks

i've found Bens script 1 to work for 10.6 and 10.8 specifying not on ticking it but also the location of the auto configuration file. To others looking i really would suggest Bens method.

Ha ha ha Tim, my virtual Pimp!!

Tkimpton - do you have script that runs both that you can share?

link i posted.

This is what i use

I thought I'd update this post with an edit of Ben's script. This should tick the Auto Proxy Discovery checkbox in 10.8.

This won't solve the OP's problem but at least it will provide an answer to those folks on later versions of the OS who find this thread via a Google search.
