thanks, you made me smile. my macbookpro has been very slow to open and to receive commands since about 5.26.17. the mouse and the calculator are not working properly. i opened in safe mode a few times and ran disk repair and restart. this seems to help a bit - but only for a short time. i log out and shut off each day. the next day i am back to where i started.

whenever i have issues or notice changes i check "about this mac" and also check the applications list to see whether there have been recent updates. today, after encountering the slow open and uploads from the desktop to itunes to my browsers, along with the slow mouse responses, i saw that apple updated the MRT app. i don't know what that means.

thank you for any info you can provide.

p.s. i did go to the app store and purchased the ad doctor app - and things are much improved - except for the calculator which only allows the minimize option - when it is already minimized. when i press zoom, the numbers appear very large outside of the calculator. i'm thinking the version of calculator i have is not compatible with mac os el capitan (i have the latest version).

It is not the MRT app, but if I am correct, the MRT got infected by some malware which sends it into a loop with increasing memory. Also you are unable to delete it. I had the same problem, and what helped was the app malwarebytes. Test version is fully functional and free (www.malwarebytes.com)

My MacbookPro was very slow suddenly. A proces called MRT used very much memory. I did run the Malwarebytes app and everything went back to normal.

It is Apple's "Malware Removal Tool", found here: /System/Library/CoreServices/MRT.app/

A little context would help us to help you. My first guess would be that it is a Singapore/Manila MRT app that displays routes and maps of their transit system.
