How to get rid of “TypeInitiatorfld” will damage your computer" pop-up on MacBook Air?

lucian277, please follow the instructions below.

The report you posted does not indicate the presence of a Time Machine backup. Ensure you have a reliable backup of your Mac in case something should go wrong with continued troubleshooting. To learn how to do that, please read Back up your files with Time Machine on Mac - Apple Support.

• If you do not back up your Mac, by definition the prospect of spontaneously and permanently losing all its contents does not concern you. This has nothing to do with the problem at hand; it is just a statement of facts.

Next: This step will prevent the scam products from loading so that they can be removed while they are inactive. Restart your Mac in "Safe Mode", and log in: How to use safe mode on your Mac - Apple Support. Starting in Safe Mode takes longer than usual so let it finish. The rogue processes affecting that Mac are inoperative in "Safe Mode".

Open the following folder:

/Library/LaunchDaemons

To open that folder, copy the entire line above and paste it in the Finder's Go menu > Go to Folder... field.

Make it look like this:

... then click the Go button. A Finder window will open.

In that Finder window, locate and drag the following files to the Trash:

com.TypeInitiator.system.plist
com.TypeInitiatord.plist

In addition to those two, drag all the files with nothing but a long string of alphanumeric text to the Trash.

The first example is

com.2235906695434282576<etc>...plist

There may be several others. Drag all of them to the Trash.

In the same manner as the above, navigate to this next folder:

~/Library/LaunchAgents

To open that folder, copy the entire line above and paste it in the Finder's Go menu > Go to Folder... field. Make it look like this:

... and click the Go button. A different Finder window will open.

In that Finder window, locate and drag the following files to the Trash:

com.TypeInitiator.service.plist
org.wrxtrolr.plist

... as well as all the files containing nothing but a long string of alphanumeric text in their names. Example:

com.73BAFCE7.0D50.4DE8.929A.5176FE3BCF9E.plist

There may be several others. Drag all of them to the Trash.

In the same manner as the above, navigate to this next folder:

/Library/LaunchAgents

Notice its pathname is different than the other two. The Finder's Go menu > Go to Folder... field should look like this:

Click the Go button. A different Finder window will open.

In that Finder window, locate and drag the following files to the Trash:

• (nothing needs to be deleted)

In the end, you will have inspected and modified the contents of the following three separate folders:

/Library/LaunchDaemons

/Library/LaunchAgents

~/Library/LaunchAgents

Please review all three and confirm their contents no longer contain any of the numerous files EtreCheck categorized as malware.

You can then restart your Mac and log in as usual. Evaluate its operation and ensure everything is working as you expect it should. If you should still experience the same problematic dialog, or if something else unexpected occurs, please capture a brand new updated EtreCheck report and post it in a reply.

System Software:

macOS Big Sur 11.6 (20G165)

Time since boot: About 14 hours

Update macOS. To learn how to do that please read Update macOS on Mac - Apple Support.

Finally: If any of the above actions result in abnormal operation or if something else stops working, the easiest way to recover would be to restore the Time Machine backup you created as a prerequisite, so the importance of that fundamental step cannot be overemphasized.

You will not find a file by that name anywhere on your Mac.

Consider using EtreCheck. It is likely to identify the file containing the process that causes that dialog to appear. Instructions are here: How to use the Add Text Feature When Posting Large Amounts of Text, i.e. an Etrecheck Report - Apple Community. Post that report in a reply to this Discussion in accordance with those instructions. Eradicating the problematic file will be a separate step, pending your reply with that report.

Unfortunately these steps did not resolve our issue, the plist files were not there , resulted in needed Malwarebytes to remove successfully.

SiskoUrso, you never provided any details regarding your concern. This is the reason I addressed my reply specifically to lucian277.

Instructions provided for one person's Mac will not necessarily apply to anyone else's Mac. Each individual user is encouraged to read and follow About those "<app> will damage your computer" messages - Apple Community, and provide his or her own screenshots if individual attention is desired.

Followed your directions exactly and omg it worked!! Thanks so much. Only thing to add was after restarting the box still popped up. All I had to do was open in folder and throw in trash.

thanks again
