Random Safari Networking high CPU usage

Hi all,

Ever since I updated to the latest version of Sierra (I had 10.12.0 previously), I've been having problems with the Safari Networking process randomly hogging all my CPU. Literally all 400% of it.

I've got a 2015 15" rMBP, if that helps. The issue happens very regularly (every couple of hours), I quit Safari, it goes away, and then it comes back soon afterwards. It's getting really annoying and I'm trying to figure out a way to fix it. Can anyone help?

Thanks!
 
Make, model, year, computer illiteracy, tendency to follow random links, have you attempted PRAM reset, run ONYX automated cleanup, run antivirus/antimalware [malwarebytes is a good free tool]

Hello you too. I've given the make/model/year in my post? I'm also not "computer illiterate" as you put it, I don't follow random links and don't open random programs.

I've tried a PRAM reset before, with no result. I've also tried turning off all Safari plugins and that didn't work either. Since the issue started appearing after I updated the OS (again, something I stated in my post) I thought it may be a bug or have something to do with Safari because I doubt a virus would start hogging the CPU only after an OS update. There are also no other signs of viruses (no random pop-ups, my computer isn't slow)
 
I would uninstall Adblock and reset your wireless network see if that helps.
 
I'm assuming you updated from the Mac App Store. If you jumped from 10.12.0 to 10.12.3 you need to update through downloading the combo update.

https://support.apple.com/kb/DL1905?viewlocale=en_US&locale=en_US

This will combine updates from 10.12.0 till 10.12.3. Use the Mac App store to update when you're going to update between consecutive editions 10.12.1 to 10.12.2, 10.12.2 to 10.12.3, not 10.12.1 to 10.12.3 and so on.

I hope that helps.
Cheers

Ooooh, really? I've never done that before when skipping between updates. I just assumed that since the MAS let me update, it must have been fine.
What do I do now though? Now that I've already used the Mac App Store? Should I still get the combo update even though my system is up to date?

Well, you could try and delete that. Or try another one.

If it doesn't work, then I'd take the steps in this article under the "manual" section:
https://www.macissues.com/2015/06/22/how-to-fully-reset-safari-on-your-mac/

Then reboot.

Thanks, I'll try that, hopefully it works!

Yes, download it and install it just like any other update.
