I've been having some speed and battery charging issues on my late 2012 MacBook Pro (15" i7, running 10.9.5). So based on some articles and forum posts, I decided to reset the System Management Controller (SMC) using the Shift-Control-Option-Power Button while the computer was shut down. Upon restart, everything seemed fine, except most websites will not load now. Weird thing is that a lot of other internet traffic is still fine. "Normal" sites (news sites, Amazon, weather sites, Apple, MacRumors, etc) will not load. Browser says it is waiting for a response and it times out. However other sites and web traffic that seem more "secure" (Facebook, Twitter, Dropbox, all email, CrashPlan, iCloud) all work just fine. Things that haven't worked: Restart (duh) Modem/router reset Different networks (wired or wireless) Different browsers PRAM reset Time Machine restore from previous day when it was working Things that do work (but aren't fixes): Everything through the Tor browser Restarting in Safe Boot The latter obviously seems like it would be something new I installed, but I didn't do anything except that SMC reset. Help?
