Remove Mac access

We have lots of folks here willing to assist, but your post is terribly vague.

Can you explain in detail exactly what you are trying to accomplish.

Please include the model and year of your Mac and which macOS version you are running.

Also, just taking a stab here... if you're trying to prepare the Mac for sale, recycling or other change of ownership, please follow the guidance here: What to do before you sell, give away, or trade in your Mac - Apple Support
