I updated just like everyone else did on Tuesday Morning, Oct 29th. And nothing for my job works now, I can't log in to my VPN, citrix is popping up for everything. The VPN site blames java, my macbook retina, 10.9 maverick version, is blocking the plug in for java. My work suggest I downgrade my safari to version 6 or 5. Applecare won't help me. Saying they don't support downgrading. Gave me a number to some "ABC Computer Shop". I have this apple device that I paid over a thousand dollars for, and can't use it to make my money. I'm so upset with nowhere to turn.
