Any solutions here.
I get message:
Safari cant open the page
http://www.mac.com/WebObjects/Welcome.woa/wa/login?ri…d=D6vttdCK3U7hyEj nohUFx0&aff=consumer&cty=US&lang=en” because it could not connect to the server www.mac.com...
In: Apple - Discussions > Safari > can't connect .mac pages

Until I see a good answer from Apple or have another issue, I am just going to use IE due to time constraints. Once I got this message, I could not connect to any web sites with any browser, but I could use the network tools to ping some websites (but not mac.com)
I had some success cleaning out the libraries ->cache folder then shutting down.
Also, I noticed that in Activity Monintor, the kernel_task was using up most of my system resources.
I hope some of these hints help someone come up with a solution.
