I am running OSX 10.11 PB1 on MBA 2011 fresh install.

When I check activity monitor there is a process called MRTAgent that constantly shows as not responding. Does anyone else have this issue? I have sent a bug report to Apple via their feedback assistant app.

yeah this happened after I downloaded java6 for el capitan - according to this article: a-look-at-apples-flashback-removal-tool, it's a malware search tool - probably broken in capitan.. and they give instructions for how to uninstall in the article. I'm about to try, wish me luck!

First, disable rootless

Code:
sudo nvram boot-args="rootless=0";sudo reboot

Then delete the files

Code:
sudo launchctl stop com.apple.mrt
sudo rm /System/Library/LaunchAgents/com.apple.mrt.uiagent.plist
sudo rm /System/Library/CoreServices/MRTAgent.app
sudo rm /usr/libexec/MRT

edit: I also tend to nvram reset the mac (hold down 'cmd - alt - p - r' during boot up) during the first boot, and then first aid the partition in disk utility after the first load. that seems to reset rootless without additional commands and fixes bugs sometimes

Please tell me off this worked, as I am having the issue as well.
