Wife's 17" macbook pro stopped being able to use non-secure web connections after the 2016-003 update - only URLs that default to https seem to function at all. Even the App Store doesn't work properly.
How can I back it out?
MacBook Pro, OS X Mavericks (10.9.5)
Do you have a backup that pre-dates the install that you could restore from?
Unfortunately, I only have a time machine backup. Which doesn't appear to consider OS files worth backing up.
I'm going to attempt to update to El Capitan With a USB stick and see if that gets it functional.
Well that was a waste of time.
Now have an updated and still nonfunctional laptop.
But I guess that means I need to move to another forum.
I have no issues with latest security update. We must be missing something here but not sure what. Have you tried a different browser?
What isn't working with the App Store?
Try resetting the App Store and Clearing Cookies.
Safari doesn't load a page or webpage items are missing
After updating to El Capitan, the App Store now works. Probably because they've moved more of it to secure connections. The Mavericks version would complain about not being able to connect.
Still cannot connect to non-https servers with either Safari or Firefox. Event local network servers. Quite annoying. I can't find a single configurable thing that would do this - pf.conf is mostly empty, and should only have an effect on incoming connections.
wget doesn't even work :-/
Is there some known malware that would cause this? So annoying.
Malware like anti-virus apps can cause issues like these. 🙂
Any of those installed?
Otherwise, can you post an Etrecheck report?
Not intentionally. The only non-Apple code on this machine is MS Office and Firefox.
Thanks for the link, I'll see what EtreCheck says, I've not heard of this tool before.
EtreCheck was an excellent suggestion. It appears she has at least two bits of malware. The primary offender just happened to infect on the same day as the security update.
Adware:ⓘ
/Library/LaunchDaemons/com.centripetencyUpd.plist
/System/Library/Frameworks/VSearch.framework
2 adware files found. [Remove]
Unknown Files:ⓘ
/Library/LaunchDaemons/com.snock.plist
/etc/snock.sh
/Library/LaunchDaemons/com.urothl.plist
2 unknown files found. [Check files]
This snock thing is the primary offender as it appears to be only partially in place and is sending all port 80 traffic:
Sues-MacBook-Pro:etc sue$ cat /etc/snock.conf
rdr pass inet proto tcp from en1 to any port 80 -> 127.0.0.1 port 9882
pass out on en1 route-to lo0 inet proto tcp from en1 to any port 80 keep state
pass out proto tcp all user Monandria
Now to do some scrubbing.
