DominantPartitiond removal

My MacBook air is Intel based. I get "Dominant Partitiond will damage your computer: EVERY TIME I boot up. I have run multiple virus/malware removal tools (free and purchased) and they say that no malware is detected.


BUT, I will get this message every time I boot up.


Can this deeply buried software be removed by doing total backup and then erasing entire MacBook, and then reinstall everything?

DominantPartition is an adware-type app with browser hijacking traits. This application operates by running intrusive advertisement campaigns and making changes to browser settings - in order to promote fake search engines and are typically are distributed through download/installation setups of other programs.


You are correct that this malware/adware does imbed itself into your system. AFAIK, the following are where they are installed:

  • ~/Library/Application Support/.[random_string]/Services/com.DominantPartition.service.app
  • ~/Library/LaunchAgents/com.DominantPartition.service.plist
  • /Library/Application Support/.[random_string]/System/com.DominantPartition.system
  • /Library/LaunchDaemons/com.DominantPartition.system.plist


I'm surprised none of the freeware/paid anti-malware apps did not detect this. Per chance did you try using Etrecheck?
