All internet-based apps suddenly slow; fan speed high

All web-based functions drastically slowed down on Sunday July 24

  • by "slow" I mean 20-100 seconds just to connect (once connected, load times are normal, even fast)
  • affected apps: Safari, Firefox, iTunes, App Store, etc.
  • this happens on all the wifi networks I use (each with it's own ISP, the speeds of which range from 25mbps/10mbps up to 100+mbps/100+mbps)
  • whenever I am using web-based apps, the fan turns on and runs at full at or near full speed (if the apps are merely open, but not actively connecting/reconnecting to anything, then the fans slow down.)



When using web-based apps, the following processes run around or above 100% CPU (in order of frequency):

  • Safari Networking
  • acwebsecagent
  • nsurlsessiond
  • syncdefaultsd
  • cloudd



None of the following troubleshooting has helped (I tested after each change):



The problem goes away when I...

  1. run Safari in a guest user
  2. run Safari from recovery mode


Other info:

Mid-2013 Macbook Air

OS X 10.11.6


This is my third day of troubleshooting. I really need to get back to work, (but work requires internet apps to work). I’m desperate.

MacBook Air, OS X El Capitan (10.11.5), null

JimmyCMPIT,


(1) Thanks for responding.

(2) I reset the SMC

(3) I booted into safe mode

(4) I rebooted normally


The behavior continues. Worse,...


(5) Now some websites are not either (a) not loading or (b) not loading correctly (e.g., webages load raw-text without images, styling, etc.).


I'm not familiar with etrecheck.com. It is loading now. It might be awhile until it loads and I can do something with the website.

Here are the logs from around the last time I tried to load a webpage in Safari.

It was around 11:24:40 (plus or minus a bit). The webpage took a long time to connect (almost 100 seconds) and the fan kicked on.


Logs:

One more log from another instance of the behavior (aside: discussions.apple.com is displaying a minimal non-styled text in Safari as I write this):
