MacOS Sierra safari 10.0 overheating laptop

This is the Mac Pro desktop forum. I requested your post be moved to the MacBook Pro laptop forum or other appropriate forum.

I am not sure if this is cuz of Safari but I have the same issue after upgrading to Sierra. I have checked Activity Monitor and reset SMC control, gone back to Capitan etc. The most high CPU usage that I found with activity Monitor was Launchesservsd which was using average 25% of CPU. I thought this was not a big of deal overall. However, Fan keeps running constantly and heating up after 5 or 10 mins laptop wake up under normal use.

This is not just a Safari issue. CPU also heats up using Firefox, as usage is >200%. I've now tried Chrome, and it works fine--no CPU overheating. Mid-2012 MBP i7 quad core, 8gb.

It's not just a Safari or Firefox issue. I had neither running when I ran Etrecheck and got these results. Webcontent in Mail.app is hitting 200% CPU. While the CPU temp is not 160 ℉ with Mail running (as with Safari and Firefox), it's still elevated, 135 ℉

Back up your data and then reset to the factory os and upgrade to the official realize. Had this problem when upgrading to the beta. Very unstable.

If you do not want to fresh install and only restore data, you can try uninstalling ClamXav and Trusteer since those sometimes caus problems

Here what I did and solved the issue "for now"

Backup your laptop with time machine if you have prior backups that would be better cuz you could go back to Capitan. But I didn't have any backup so I backupped mine after installed Sierra which is not the best idea but I got no choice.

Once I backupped the computer, I wiped out my HDD and reinstall Sierra. then I used Migration Assistant and moved only "Application" and "document and data" back. because I have tried moving back Application and Computer and Network setting back, problem wasn't solved. so I believe the overheating issue was caused by the combination of prior computer setting and Sierra.

so

Backup with time machine>erase the HDD>clean install Sierra>migration assistant

I wouldn't recommend restoring the backup from time machine, it would probably bring the causes back to laptop again. loosing prior computer and network setting should not be a huge loss for anyone I guess.

I had removed Trusteer from Safari some time ago because it was causing Safari to run slow, especially at startup. I didn't know that it was still being run at laptop startup. The Uninstall Trusteer app was corrupted, so I downloaded a new one and uninstalled it. Mail, Safari, and Firefox are all running normally now (in Activity Monitor) and CPU heat is a non-issue. Thanks.

I am not aware of a problem resembling this particular one having ever been caused by ClamXav.

I stopped the overheating by removing Rapport - Trusteer software.

Thanks!
