Hey there!
I've had similar issues (which brought me here) and when I run these, I get through the first three ok, but once i get to the last 3 it all falls apart. It says that the "Domain (com.google.Chrome) not found. Defaults have not been changed."
It doesn't matter what user I try it on, new or existing. Any ideas?
Let's try these steps:
STEP 1. Let's check if there any malicious profiles installed on your Mac:
- Go to System Preferences.
- Click Profiles.
- Select any profile 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.
STEP 2. Let's reinstall Chrome.
In many cases, changes to Chrome may not be fixed with a simple browser reset. In such a case, it will be easier to completely remove Chrome and all data, then reinstall. To do this, click the Finder icon, from the menu bar. Choose Go, and click Go to Folder, then paste one of the below paths into the window that opens.
You will need to delete all of the below items, but before doing this be aware that this will delete all data for all Google apps you have installed, such as your bookmarks, so you will need to export them before doing this.
/Applications/Chrome.app
/Library/Application Support/Google/
/Library/Google/
~/Library/Application Support/Google/
~/Library/Google/
~/Library/Preferences/com.google.Chrome.plist <<<< The "~" indicates that it's the current user's Library which is often invisible in recent versions of macOS. To get to it you must hold down the Option (sometimes labeled Alt) key down and select Library from the Finder's Go menu.
After deleting all of the above files, restart your device. You can now download and re-install Google Chrome on your device. You will need to import any exported bookmarks or other data, and may need to reinstall any other Google apps that you use.
Let me know if these steps fixed your issues.
