Hi, I'm so happy I found these forums. Maybe someone can help sort this problem out. It's my first time ever an Apple update gets me some serious drawback and I'm with Apple since 1982!!! This morning Tuesday June 11, I said yes to the Apple update 2013-02. Done without any hassle of course. Right after the update all of the browsers I used: Safari, Chrome and Firefox almost lost half of their speed. It took 65 seconds to load the CNN homepage, same to load the MacRumors register page. Plus the pages now pop up almost fully loaded when there was kind of a progression before. I give it to you: I'm on old stuff: white Intel iMac late 2006, Snow Leopard 10.6.8. I'm about to trade this oldie for a 27 iMac but I still want to know what happened and what there's to do to get back some speed. I have high speed Internet 20 mbps. Safari has been reset. Help and cues are very welcome.
