I have an old iMac running High Sierra. Using Activity Monitor I noticed that I have an app named SilentCleanServer running This program is using some CPU time and it has over 2,000 files associated with it. From looking at other sites this app is from Mobi. I would like to stop this app but can't manage to do so. From Activity Monitor I can quit the app but it immediately restarts. When I try to delete the app it says it can't because app is open. But when I kill it, it restarts before I can delete it. I don't necessarily want to delete the app if I can just stop it from running.

Is there a way to stop this app from restarting?

  • This discussion at Apple Community should give you some clues as to how to stop this.

This Apple Community discussion thread may have the answer:

Try deleting the "com.imobie.PhoneClean" and "com.iMobie.SilentCleanServer" folders in ~/Library/Application Support.


Theres an underlying silentcleanserver app, which is located once you "show all contents". I uninstalled and its gone!
