I have a MacBook Pro (macOS Mojave) laptop and have recently noticed a suspicious process in Activity Monitor with this name : imklaunchagent

enter image description here

I checked this folder: /System/Library/Frameworks/InputMethodKit.framework/Versions/A/Resources/imklaunchagent and it seems imklaunchagent and its related files cannot be removed. I tried to remove it via Terminal and this message showed up: "Operation not permitted". However, in "Security and Privacy" of "System Preferences", I chose Terminal to have full disk access, still can't delete the file and the same message appears.

I installed the free version of Combo Cleaner and it detected other viruses, none of which are imklaunchagent. Is imklaunchagent a malware? How can it be deleted?

    Why do you consider this process to be suspicious?

  • @nohillside It seems I was wrong, this process itself is not harmful for Mac.

You can't (see † below) remove that file because MacOS doesn't let you (or anyone) alter the contents of /System. Only Apple can write to that location.

MacOS does that to ensure the integrity of the OS. In other words, if it's in /System, it's part of the OS.

† By 'can't', I mean in the normal running of your computer, unless you yourself follow a particular procedure which no active software can perform by itself as a means of corrupting your system.

    It's no problem at all (but unwanted) to remove the file (either by disabling SIP or booted to Recovery Mode)! IMHO it's more important to indicate that the process imklaunchagent itself is completely legit. It may "[h]owever oftentimes [be] targeted by dangerous Trojan Horse infections that try to hijack it or disguise themselves as it."
