I'm having problems with 10.4.6 and any application (it seems) that uses WebKit. Initially, the problem manifested itself as Safari crashing a few minutes after launch for almost any URL. Restarting and going to the same one worked OK. Then things progressed and Safari now cannot connect to any site whatsoever. It is stuck, with "connecting to www.example.com" in the status bar. I can hit escape and the app recognizes that, but never connects.
I've noticed that the problem also exists in other applications:
Mail.app can't load images in HTML mail Software Update can't get a list of new software RealPlayer can't check for updates Dashboard widgets that access the net never load anything iTunes can't access ITMS my VPN client can't connect (Juniper, I think) Delicious Library can't load details from Amazon
Other applications work fine:
Camino/Firefox Quicken stock quote and news downloads Mail.app can fetch and send mail ssh
I have tried all of the following with no success:
rebooted created a new user re-applied the 10.4.6 combo update pulled out Safari and WebKit from combo update with Pacifist re-installed OS X using archive & install
The only thing I haven't tried is a complete reinstall by wiping the parition. That's going to be time consuming since I'll have to reinstall my applications. Does anyone have any advice or suggestions?
