Hi, ever since I've upgraded to 10.14.5 Safari on my MBP keeps lagging every once a while – it eats 100 % of one core and iStat Menus shows it as "zombie" (red) for that time. I've tried disabling all plug-ins, it didn't help. I cannot find anything relevant in logs either. Do you have some ideas? Thanks.
Got a tip for us?

1. Disable all extensions. May be one of them is not compatible with 10.14.5 version of Safari. May be there are updated versions?
2. Create a new user and try to run Safari there, that will tell you if this is system wide or user specific.
3a. If it is system wide, I would reinstall 10.14.5 using combo installer. Ideally, I would reinstall just Safari, but I think this is the only way to reinstall Safari.
3b. If it is user specific, something is wrong with Safari specific setup in that user account. What, not sure. Clean cache seems good idea, remove extensions,...
Before you do ANYTHING., backup your computer.

Poor JavaScript coding is occasionally the culprit.
Or dare I say, excellent JS coding that uses your computer to hash crypto in the background while you are viewing a page.
I recommend the next time you see the 100% or feel the slowdown to temporarily turn off JS and reload the page. See if that changes anything.

I have the problem even when there are no Safari tabs open at all - there's a rogue Safari Web Content process that doesn't seem to ever shut down. Quitting Safari seems to be the only solution once this happens.
Have had the same problem while using Wipr or Adguard.
