DominantPartitiond will damage your computer

Hi HatiM1,

When this prompt appears, select Show In Finder. Then, move the application or file(s) to the Trash. Restart your computer afterwards.

Additionally, you might want to run a manual scan with Malwarebytes.

This happened to me too. I was not able to access Safari or Finder or any App.

Finally i was able to resolve it by following these steps that Apple provided:

1 Shut down your Mac.

2 Press and hold the power button for 20 seconds as your Mac starts up.

3 Release the power button when you see the startup disk (like shown in the image).

4 Select your startup disk, press and hold the Shift key, click Continue in Safe Mode, then release the Shift key.

5 Log in to your Mac. You might be asked to log in again.

Then try to download Malwarebytes for a virus scan.

If Malwarebytes is still not downloading (mine didn’t)

The next step is to restart your computer (without safemode).

And try downloading Malwarebytes again.

(Mine downloaded after trying all the above steps and I was able to get rid of the virus).

Goodluck! I know it’s a scary experience.

I’m not sure what others are doing to remove the DominantPartitiond malware (or whatever it is...) but here’s the method I used when Malwarebytes would not even detect the issue, much less fix it. Another similar malware, CleanParameterd, can also be removed following similar steps:

You will need to locate this folder:

/private/var/root/Library/Application Support/.DominantPartition.dp

Because of hidden files and locked folders, you will likely have to open each step manually. To find the initial “private” folder, toggle show hidden files with the “command+shift+.” shortcut. The root and Library folders are locked, but using “get info” allows you to change the permissions to gain access. The final folder is also hidden. Once you get to the last folder (.DominantPartition.dp) delete it and all contents, then empty the trash. Restart to verify that the pop up no longer occurs.

I had the same problem starting last evening. Norton anti virus did not detect DominantPartitiond.

I downloaded the free trial of Malwarebytes and ran a scan. If found several adware, non with the above name.

Rebooted the computer as directed and its gone.....for now.

If you are still having this issue navigate to System Preferences>Network>Advanced>Proxies and ensure there are no proxies checked. THIS WILL NOT REMOVE THE ADWARE but will allow you access to the internet.

Does the warning appear if you boot into safe mode? How to use safe mode on your Mac - Apple Support

Hi, I had the same problem today. And the Apple Support Team guided me to fix it already.

https://getsupport.apple.com/

First, you install Malwarebytes.

Second, following Malwarebytes's guide, you need to change the setting of your privacy on the System Preference.

Third, restart your PC.

The notification disappeared when I turn on the PC again! Hope this information helps you too.

It is malware. Since you can’t connect to the internet, you will have to restore from time machine backup. Go to macOS utilities (command-r) upon startup. Select reinstall from time machine backup and proceed from there.

Contact Apple they will talk you through what you need to do to get rid of it. Malware bytes detects it but cannot remove the annoying pop up only a system reset works. Also just worthwhile to say this issue seemed to arrive following download of big sir although Apple say they would be surprised if that was the case.

Where to Go from Here:

I would reinstall the macOS anew. Simply put: Erase the hard drive, and then install it, anew. Once installed, transfer is all over using Migration Assistant. How to do so (In Depth):

I. Backup: the Mac

II. Erase: the partition

1. Boot: into Recovery Mode [Hold Down: shift key upon boot]

2. Select: Disk Utility

3. Erase: the Hard Drive

III. Reinstall: the macOS

IV. Transfer: Items over from the backup using Migration Assistant.

Oh no! That is malware! Too bad you pressed on it. Now you have malware on your computer. Immediately download Malwarebytes to fix it. It has a good reputation among the seniors on the community. I use it and it is very good.

Give it a go! It works really well!

Malware bytes as mentioned by others solved my problem immediately. I was skeptical that it would cause more problems but it was legitimate and identified and cleared the problem extremely quickly.

Invest in Malwarebytes it’s not that expensive it solves the problem. Also rebooting from time machine could be a bit risky when this soloution could prevent further malware.
