my mistake it did work, i just restarted Safari :)

Apple have screwed with things again!

Safari 6.0.4 no longer loads through proxy PAC!!!

Any ideas?

Broken in Safari 6.0.4 logged under bug 13746154 to Apple!

Apple developers said to put it in /Library/Managed Preferences/

When i said that was a stupid idea in the enterprise because of flushing of mcx caches, having to delete etc, they closed the call!

Thanks Apple bit to busy with your WWDC, 10.9 and ios 7 eh?

Local PAC files are no longer supported. They must be hosted on a webserver. That's nice of you Apple.

Ah, that explains why we never had the problem. Hosted has benefits...
