Процесс MRT с использованием большого неограниченного объема памяти
Сегодня у моей машины закончилась память. Я пошел в Activity Monitor, и он показал процесс под названием MRT, использующий много памяти. Я перезапустил свой компьютер, надеясь, что это поможет, но даже после перезапуска я вижу, что объем памяти MRT увеличивается примерно на 0,01 ГБ каждые несколько секунд.
Я на MacOS Sierra 10.12.6 на MacBook Pro (Retina, 15-дюймовый, середина 2015 года), 16 ГБ ОЗУ.
Похоже, есть сообщения о том, что MRT использует высокую загрузку ЦП и как его удалить здесь . Но я бы предпочел не удалять его, потому что он сканирует на наличие вредоносных программ.
ОБНОВЛЕНИЕ: Я даже попробовал шаги, описанные в ссылке выше под «Вручную удалить MRT», но, похоже, это не сработало, процесс MRT все еще работает и продолжает увеличивать использование памяти.
Три системы, которые работают вместе для защиты вашего Mac от вредоносных программ:
Итак, это процессы Apple, и если они заняты, вероятная причина — вы заражены или скомпрометированы. Это может быть ложным срабатыванием, но вы можете рассмотреть возможность включения привратника и sip, если вы отключили их и посмотрите, сможете ли вы очистить свою систему. Если нет, то вам может потребоваться чистая установка с исправлениями, а затем осторожно вернуть данные, но не какие-либо программы или вредоносные программы.
Как разработчик, я бы использовал значок шестеренки в отображаемом окне, и, пока выбрана MRT, запустил Диагностику системы . и отправил отчет об ошибке / radar / escalate в службу технической поддержки Apple Engineering, чтобы они могли выяснить, есть ли у MRT утечка памяти — это также очень вероятный сценарий, если вы уверены, что вам не нужно удалять вредоносные программы каждый раз, когда работает ваш Mac.
Предполагая, что вы просто хотите узнать, нужна ли вам очистка (или для тех, кто не является разработчиком и имеет схожие проблемы), продолжайте ниже
Отличное место для начала, если вы обычно не удаляете вредоносное ПО, — MBAM — https://www.malwarebytes.com/mac/
Как всегда, будьте немного скептически настроены / осведомлены о бесплатных инструментах, так как инструменты «защиты или очистки» от мошеннических / змеиных программ на самом деле являются компромиссными, злонамеренными и неправдивыми в отношении того, что они делают. Если вы загружаете что-то из бесплатных агрегаторов, вас может даже обмануть что-то, что не соответствует названию в файле или описании.
Я не отключил бы MRT, если он у вас горячий, если вы не уверены, что не скомпрометированы.

Question: Q: 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
MacBook Pro (17-inch Late 2011), Mac OS X (10.7.5), SSD drive maxed RAM 😉

It downloads in the background automatically within 24 hours, as long as your computer is awake at the random time it uses to install such things.
If you can’t wait that long, you can speed things up by copying and pasting the following command into a Terminal window. The Terminal app is in /Applications/Utilities/
sudo softwareupdate —background
You will be asked for your admin password. When you enter it nothing will be seen. Just hit enter after typing it.
The only feedback you get will be «Triggering background check with normal scan . » and it may take up to five minutes before the background process completes. You can follow it’s progress, if you want, by viewing your install.log in the Console application.

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.
Aug 26, 2017 4:43 AM
Thank you kindly for the response! Will try this!
Aug 26, 2017 4:59 AM
Hmmm. It seems this Malware thing is a scam. You should not recommend that to people!
Aug 26, 2017 5:03 AM
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?
Aug 26, 2017 5:07 AM
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
Aug 26, 2017 5:09 AM
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?
Aug 28, 2017 7:29 AM
No, I’m confident that this was an MRT problem caused by some adware/malware on you computer that MRT was unable to properly deal with. At least a dozen others were reporting the same situation here in the Forum since Friday.
Apple updated MRT automatically for you in the background over the weekend, which fixed their problem and hopefully allowed it to remove that adware/malware for you. Rest assured that this specific issue is gone.

How can you download the fix for the MRT CPU consuming problem?

Hi Mad Macs! I really appreciate all your efforts in helping us solve this. Although my problem is not completely solved it has gotten much better. I think its time to research more into what is happening and see if there is a solution on my end. Thank you again. You were the only one here trying to help.
Aug 31, 2017 5:58 AM
Glad that took care of that issue.
Both EtreCheck and Malwarebytes might give you some insight into your remaining problems. I’ll add one more recommendation for DetectX. All three of these were developed by fellow troubleshooters here in the Forum that I converse with on a daily basis and know to be focused on helping users without contributing to their problems. All are fully functional in trial mode and easily removed if you no longer have need for them. If they are useful, then I would encourage you to support their efforts and in some cases, their livelihood.
If you have additional questions, be sure and start a new discussion in order to draw maximum interest. Only a couple of us are likely to spot any additional you post here.

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.
Aug 25, 2017 7:06 PM
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.

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.

Mrt.app Mac
Mrt.app
A new infection has been discovered attacking Mac users that has hijacked MRT.app in your Mac’s library. It is thought to be a malicious virus that affects the legitimate processes of Macs victims so that malware remains persistent in them.
In the next lines, the visitors to this page could learn about the specifics of a software piece known as Mrt.app. Due to a big number of complaints about this program, we have decided to dedicate the next paragraphs to explaining what Mrt.app actually is, why it’s typically deemed unwanted and how anyone who might presently have it on their computer could have it removed.
Obviously, this could really get on one’s nerves and the majority of users tend to get really frustrated by the generated ads. In fact, this app we are currently focusing on isn’t not one of a kind. There’s a whole category of software programs and applications that are infamous for their tendency to spam the users’ screens with intrusive advertising materials. Mrt.app is merely one of the more recent representatives of this software group. That said, since you’re currently reading this, then you’re most likely looking for a way of getting the unpleasant app removed from your computer. The good news we can give you here is that uninstalling the adware wouldn’t be too difficult if you use our guide that you can find below. Adware programs are not dangerous and malicious viruses like Trojans, Spyware, Ransomware and so on and removing them would normally cease and end all the irritating and unpleasant activities and effects that they might have on your computer. So, if you are currently having your browsing experience obstructed by the endless stream of ads coming from the pesky adware, be sure to take a look at the following instructions and/or check out the suggested professional anti-malware tool available in the guide as it could also help you take care of the adware-related issue.
Mrt.app on Mac
The main problem most people have with apps like Mrt.app is that such pieces of software tend to fill the user’s browser with different advertising materials that are normally really irritating, invasive and obstructive. If you have Mrt.app on your computer, then your Chrome, Firefox, Safari or any other browsing program on your PC is likely getting flooded with nagging banners, box messages, pop-ups and page redirects each and every time you try to use the browser.
Despite their relative harmlessness and the fact that adware programs and applications are not technically computer viruses, most software that falls in this category is regarded as unwanted mainly due to three reasons. The first and most obvious one is the irritation coming from the frequently generated online ads. The second reason is the fact that due to the uncontrolled nature of the ads generation, there’s usually a certain risk that some of the adverts could link the user to shady, unreliable and unsafe online locations. In the worst case scenario, you might get your PC infected by some highly malicious virus program such as a Trojan Horse or a Ransomware. The third problem with adware apps is that they oftentimes tend to collect data from the users’ browsers. Normally, the collected data includes search history, visited pages, overall browser history, preferred sites and so on. Such browsing activity monitoring is done with the purpose of determining the preferences of the user and later feeding their browser with relevant adverts which would increase the chances of those ads getting clicked upon. Since adware apps earn money for each click a user makes on an ad, this targeted advertising effectively increases the overall profit that an adware program is able to generate. Of course, nobody would want to have their browsing activity monitored which why this is yet another reason why adware programs are typically seen as undesirable.
Mrt in Activity Monitor
Mrt in Activity Monitor cause high CPU usage that slows the system down and you can try to remove it. If Mrt is in Activity Monitor apps are pausing because they can’t run.
Adware apps sometimes have official sites but in the majority of cases their creators rely on other ways of getting them distributed. Such ways could be spreading the adware through spam messages, deceitful online requests and offers, pirated downloadables, torrents, streaming sites with shady reputation and so on. However, even a legitimate program’s installer could be used to spread an app such as Mrt.app. This is what’s called file bundling – the adware is put inside the installation file of another program as a “bonus” element that the user could choose to leave out. However, most customers pay little to no attention to the details in the setup menu which is what gets them the adware. However, if you take a few moments to look through the settings of the installation wizard of a program you want to install and opt for the Advanced setup settings, you should be able to see if there are any unwanted “bonus” components and leave them out before the installation begins.
SUMMARY:
| Name | Mrt.app |
| Type | Adware |
| Detection Tool |
