google search goes to ask.com. how to fix it on mac

This is what I would do:

1. Go to Chrome > Settings > Search engine and make sure Ask.com is not even an option. (If it's there, remove it.)
2. Go to Chrome > Settings > Extensions and make sure no Ask.com, nor any other search-related extension is installed.
3. Restart Chrome.

If the problem persists, I would:

1. Export my bookmarks.
2. Make a note of the extensions I'll want to reinstall later.
3. Uninstall Chrome completely (including its folders in your macOS user Library; you may google how to do it).
4. Install Brave instead of Chrome. :P
5. Import my bookmarks and install my favourite extensions.

(Disclaimer: I'm not a pro expert! Just an ordinary user with 25+ years of Mac experience.)

Chrome > Settings… > Search engine

Let me know if you fix.

For what it's worth, I don't think the issue has anything to do with Sequoia or your Mac. Try asking here: Google Chrome Help.
