I HAVE TRIED EVERYTHING. I went to my friends website, it told me I needed a flash update, I clicked it (stupidly), stopped the install half way through, but it was too late. My chrome is being "managed by your organization" and I'm unable to change the homepage. I've deleted all extensions, ran Malwarebytes, AVG and combo cleaner. I've manually cleared caches, uninstalled sketchy applications, uninstalled/reinstalled chrome.....everything. Nothing is working.

First, let's check if there's an AdminPrefs file on the device. If it's there, you should remove it.

  1. Go to System Preferences.
  2. Click Profiles.
  3. The list will include an item “AdminPrefs“. Select this and click the remove “” button in the lower left corner.
If there isn’t a Profiles icon, you don’t have any profiles installed, which is normal.

Next, to completely remove this browser hijacker from Chrome, we will need to uninstall the browser and delete all data, then reinstall.
To do this, make sure you’re in the Finder, click on Go > Go to Folder, then go to the below folders and delete the below files or folders.

/Library/Application Support/Google/
~/Library/Application Support/Google/

Be aware that this will delete all data for all Google apps you have installed, such as Chrome bookmarks. Export any data you want to keep beforehand.

Be sure to delete the correct item, as deleting the wrong item could cause data loss or even damage to your system or other apps. Once they're moved to the trash, click Empty.

After deleting all these files, restart the computer. Then re-download Chrome and reinstall. You will need to import any exported bookmarks or other data, and may need to reinstall any other Google apps that you use.

Hey Jack - thanks

unfortunately, I did all these steps but I'm still seeing that I'm being managed by an organization. When I go into the other accounts on my mac and open chrome, I'm not having this problem, which I find odd. Below is a screenshot of the policies this "organization" has set. Any other ideas? Thanks again.

Lets reset the Chrome Policies:
  1. Open a new Terminal window. (Finder > Go > Utilities > Terminal)
  2. Enter the following commands, pressing enter after each line:
    defaults write com.google.Chrome HomepageIsNewTabPage -bool false
    defaults write com.google.Chrome NewTabPageLocation -string "https://www.google.com/"
    defaults write com.google.Chrome HomepageLocation -string "https://www.google.com/"
    defaults delete com.google.Chrome DefaultSearchProviderSearchURL
    defaults delete com.google.Chrome DefaultSearchProviderNewTabURL
    defaults delete com.google.Chrome DefaultSearchProviderName
  3. After running these commands, quit Chrome if you haven't already done so, then launch it again and check chrome://policy to see if the same keys are still present (you may need to click the "Reload policies" button for changes to show up). If they're gone, you should be able to change your search engine and home page back to your preferred defaults in Chrome's settings.
