Click the System Preferences icon ( ) in the Dock, or choose Apple menu ( ) > System Preferences.

In System Preferences, click Profiles, then select a profile related to OptimalOrigin.

Click the minus button ( – ) located at the bottom-left of the Profiles screen to remove the profile.
Note: if you do not see Profiles in the System Preferences, that means there are no profiles installed on your Mac device, which is normal.

Check the list of installed software

The next step to remove PUPs, adware and browser hijackers is to uninstall unknown and questionable software. Using the Finder you can do this quickly and easily. We advise you not to skip this step, as it often helps to get rid of web-browser redirects and unwanted advertisements.

Make sure you have closed all web browsers and other software. Next, remove any unknown and suspicious programs from machine using the Finder.

Open Finder and click “Applications”.

Look around the entire list of software installed on your computer. Most likely, one of them is the OptimalOrigin adware. Select the suspicious application or the program that name is not familiar to you and uninstall it.

Drag the questionable program from the Applications folder to the Trash.

Most important, don’t forget, choose Finder -> Empty Trash.

Remove OptimalOrigin related files and folders

Now you need to try to find OptimalOrigin related files and folders, and then delete them manually. You need to look for these files in certain directories. To quickly open them, we recommend using the “Go to Folder…” command.

OptimalOrigin creates several files, these files must be found and removed. Below is a list of files associated with this unwanted program.

• /Library/LaunchDaemons/com.OptimalOrigin.system.plist
• ~/Library/LaunchAgents/com.OptimalOrigin.service.plist
• /Library/Application Support/.(RANDOM)/System/com.OptimalOrigin.system
• ~/Library/Application Support/.(RANDOM)/Services/com.OptimalOrigin.service.app

Some files created by OptimalOrigin are hidden from the user. To find and delete them, you need to enable “show hidden files”. To do this, use the shortcut CMD + SHIFT + . Press once to show hidden files and again to hide them. There is another way. Click Finder -> Applications -> Utilities -> Terminal. In Terminal, paste the following text: defaults write com.apple.finder AppleShowAllFiles YES

Press Enter. Hold the ‘Option/alt’ key, then right click on the Finder icon in the dock and click Relaunch.

Click on the Finder icon. From the menu bar, select Go and click “Go to Folder…”. As a result, a small window opens that allows you to quickly open a specific directory.

Check for OptimalOrigin generated files in the /Library/LaunchAgents folder

In the “Go to Folder…” window, type the following text and press Go:
/Library/LaunchAgents

This will open the contents of the “/Library/LaunchAgents” folder. Look carefully at it and pay special attention to recently created files, as well as files that have a suspicious name. Move all suspicious files to the Trash. A few examples of files: com.OptimalOrigin.service.plist, macsearch.plist, com.machelper.plist, search.plist, com.net-preferences.plist, com.google.defaultsearch.plist, and installapp.plist. Most often, browser hijackers, adware software and potentially unwanted programs create several files with similar names.

Check for OptimalOrigin generated files in the /Library/Application Support folder

In the “Go to Folder…” window, type the following text and press Go:
/Library/Application Support

This will open the contents of the “Application Support” folder. Look carefully at its contents, pay special attention to recently added/changed folders and files. Check the contents of suspicious folders, if there is a file with a name similar to com.OptimalOrigin.system, then this folder must be deleted. Move all suspicious folders and files to the Trash.

Check for OptimalOrigin generated files in the “~/Library/LaunchAgents” folder

In the “Go to Folder…” window, type the following text and press Go:
~/Library/LaunchAgents

Proceed in the same way as with the “/Library/LaunchAgents” and “/Library/Application Support” folders. Look for suspicious and recently added files. Move all suspicious files to the Trash.

Check for OptimalOrigin generated files in the /Library/LaunchDaemons folder

In the “Go to Folder…” window, type the following text and press Go:
/Library/LaunchDaemons

Carefully browse the entire list of files and pay special attention to recently created files, as well as files that have a suspicious name. Move all suspicious files to the Trash. A few examples of files to be deleted: com.search.system.plist, com.machelper.system.plist, com.macsearch.system.plist, com.installapp.system.plist and com.OptimalOrigin.system.plist. In most cases, potentially unwanted programs, adware software and browser hijackers create several files with similar names.
