What is is a legitimate program for Apple computers. MRT stands for Malware Removal Tool and the program detects and removes malware from Mac computers. It’s not a very known program and generally users are not aware of its existence, which is why they may be surprised if their anti-virus programs suddenly start detecting it. can be found at System/Library/CoreServices/ on Mac computers.


Some users have reported that anti-virus programs like Avast and Bitdefender running on their Macs have started detecting as a potential threat. Other users report that the program is using too many resources, resulting in a sluggish system and other programs not running normally. There is not much that can be done for the latter, but if your anti-virus program is detecting it, you should just whitelist it or wait for an update that would fix this false positive. Do not attempt to delete because that would be a waste of time and could result in deleted essential files.

Is dangerous?

While you may find users unhappy with certain behaviour, it’s not actually a malicious or a dangerous program. It’s part of your Mac system and you should leave it alone. However, it may contribute to your computer’s sluggishness by using a lot of your computer’s resources. But again, not much you can do about that besides disabling, which we do not recommend doing.

We should also mention the slight chance that some malware could be using the name to conceal itself. This is very unlikely but somewhat a possibility. Concealing malware as legitimate files could help the malware avoid detection and removal for longer. Even if users get suspicious of the file or if their security programs detect it, they would research it and get results saying that’s it’s a safe and completely legitimate file. But as we’ve said, this is very unlikely, and your anti-virus detecting is probably a false positive that will stop being detected after the security vendor releases an update.

Should you remove

While it can be done, the regular user will find it impossible to delete or disable, nor should they. There is no reason to remove because it’s your Mac’s built-in protection tool.

If your anti-virus program is detecting as a potential threat, wait for an update that would fix this false positive. There is nothing to worry about otherwise, as is not malware. But there’s not much you can do about it using your computer’s resources. You could try to speed up your computer by deleting certain files, programs, cleaning your browser, not running a lot of programs at the same time, etc. But do not use paid system optimisers as they are usually just scams that don’t actually do anything besides take your money.
