MRT is peaking my cpu

HI folks! I really hope someone can help. I am in Italy on a big project and on my MBP late 2011 something called MRT is peaking my cpu and causing the computer fans to go insane, raving super fast and LOUD! I first dealt with the CUP situation and it seems to be gone from the activity monitor. Now the problem is back with something called MRT in the activity monitor causing this problem. CPU is always a 90 - 95 usage with this thing.

Also I have noticed the printer preferences pane locks up the systems preferences then crashed it. No idea why.

I am at my wits end and I can't work! Please help. Thanks in advanced. P

Apple posted an update to MRT v1.21 yesterday which caused this issue for a few users. Apple is aware of the problem, has pulled this update and substituted MRT v1.20, but I don't believe it will automatically replace the one you have because yours is newer. I'm confident that Apple will fix the problem when they return to work on it, but it's anybody's guess when that might be.

Some users have run Malwarebytes for Mac to remove the adware/malware that MRT seems to be struggling with, so I recommend you give that a try first.

Any other solution will be complicated and time consuming.

Thank you kindly for the response! Will try this!

Hmmm....It seems this Malware thing is a scam. You should not recommend that to people!

Are you referring to Malwarebytes for Mac? It's definitely not a scam. It was developed by one of the foremost security contributors here in the Forum and a colleague of mine, Mr. Thomas Reed. What gives you the impression it's a scam?

because everywhere I look on this forum it says DO NOT install any 3rd party anti malware or anti virus. It will ruin your computer and is a malware itself that will ask for money constantly

Not everywhere. Search for "Malwarebytes" and you will find hundreds of recommendations from dozens of us. You will find only two anti-malware brands recommended here, ClamXAV and Malwarebytes.

The newest version of Malwarebytes includes a new optional premium feature (RealTime scanning) that will cost after the 30 day trial, but it's scanning function remains free forever and is fully functional as a manual scan with frequent updates.

So it seems MRT had nothing to do with this. Eventually it quit on its own after doing whatever it was doing. The fans went quiet and then for no apparent reason the next day...they started up again like a freakin jet airplane. Seriously disturbing. I looked at the activity monitor and MRT was no where to be found. Neither was the cupsd. I am truly baffled. Ideas anyone?
