Does anyone do personal MacBook tutoring near Danbury, CT, USA?

Here is the “cleaning” procedure intended for use when transferring a Mac (and tap or click on the following blue-text link):

You won’t be able to do all of that procedure as you don’t have the previous owner’s Apple ID; it’s intended for the seller. But you can do most of it. It’s a little unfortunate to start out with this, as what’s involved here is going to be unfamiliar for a new macOS user.

As mentioned above, Apple has online classes, and there are online websites, and various books.

The Apple Danbury store might have some local suggestions: https://www.apple.com/retail/danburyfairmall/

Welcome to the Apple Support Communities.

If you are asking if Mac computers need "cleaning" software, the answer is no. Mac computers do not need any sort of anti-virus, cleaners, VPNs, etc. The only thing they are good at is creating false marketing promises and taking consumers' money. They are all scams. In fact, anti-virus and other cleaners cause performance issues, security issues, and make macOS appear buggy. Your Mac is far worse with these types of Apps installed. Mac computers have protection built-in, which is the best protection for your Mac. For specifics on macOS Security, see: macOS - Security - Apple and Protecting against malware in macOS - Apple Support. Mac computers also have built-in storage recommendations: Optimize storage space on your Mac - Apple Support. You can even use the built-in macOS Firewall: Block connections to your Mac with a firewall - Apple Support. Other than that, all you should do is restart your Mac approximately once a week and keep macOS up to date: Update macOS on Mac - Apple Support. 

If you are asking if you can take a class or learning session on your Mac, see: Today at Apple - Apple. They offer a "Virtual Session: Getting Started with Mac".
