Hello Stephen,

Could you e-mail your report to Etresoft support? In EtreCheck, go to Help > Etresoft support.

I think I know what the problem is. Someone else reported something similar. You probably have some software version that contains the magic characters that trigger the Apple Support Communities spam filter. It is a special sequence of numbers that forms part of the phone number for an Indian astrology spammer.

Uninstall Avira. It tends to interfere with the computer's operation while providing minimal to no benefit.

SIMBL is a system hack. Try removing it.

I'm on the new 15 inch "touch pad" MacBook Pro, just updated to 10.12.2 last night so uptime was only 16 hours at the time. I had a few tabs open on Safari and everything just died (as you can see). I killed each paused process and everything is now working fine. That said Safari is now using 50GB and climbing.

Something is definitely leaking here...

Hello again Stephen,

Your system has many low-level system modifications. Any one of them, or some combination, could be causing the problem.

You have been experiencing kernel panics and other systemic issues. You could try posting one of those Safari crash logs and a hang long. It might have some information about what is going wrong.

I'm on the same boat. 100% CPU usage and memory keeps leaking with nothing except 1 empty Tab open. I don't have any extensions. Apple has been silent on Twitter on this. Hope we get a fix soon!

Safari/Preferences/Advanced - enable the Develop menu, then go there and Empty Caches. Quit/reopen Safari and test. Then try Safari/History/Show History and delete all history items. Quit/reopen Safari and test. You can also try try Safari/Clear History…. The down side is it clears all cookies. Doing this may cause some sites to no longer recognize your computer as one that has visited the web site. Go to Finder and select your user/home folder. With that Finder window as the front window, either select Finder/View/Show View options or go command - J. When the View options opens, check ’Show Library Folder’. That should make your user library folder visible in your user/home folder. Select Library/Caches/com.apple.Safari/Cache.db and move it to the trash.

Go to Safari Preferences/Extensions and turn all extensions off. Test. If okay, turn the extensions on one by one until you figure out what extension is causing the problem.

Hello Stephen,

You also have to look at your internet plug-ins. And in your case, literally all beta are off. You simply aren't running macOS anymore. You are running some home-built operating system based on macOS.

Very much the same report as my earlier post but a little more information. It takes roughly 18 hours for my Safari to get to 50GB of memory usage. It climbs whether I use it or not but apparently faster when you use it. I've had just one tab open and no difference, I have no plugins or extensions. My (touch bar) 15 inch MBP is brand new and I've installed all the software from scratch. Safari uses a single core 100% all the time from reboot to crash although when I put up the "about" to get the screen shot below it hit 200% after a few seconds and then crashed. The only recourse is to kill the process and restart Safari. Naturally when you do it uses 100% of a core again. In the 10 minutes it's taken me to write this since the restart Safari is now using 2.7GB and climbing.

First shot after it's crashed, Safari has been running about 18 hours.

Second shot a few seconds after Safari restart, note memory pressure, swap and CPU usage.

And as I type this message...
