new to Mac

So the Switching to the Mac flavor books, as suggested, would be a good start.

Also the macOS Missing Manual, by David Pogue, that matches your operating system version, is a good introduction.

I strongly suggest if you have a bookstore with a reasonable computer section and a coffee shop, you can browse some Mac related books to see if you like any better than the others before you buy. Or drink lots and lots of coffee and eat lots of snacks in the cafe.

After that Google can find you lots of things. Just include "macos" in any search string and it will give you Mac related instructions.

If you have a very specific question, the http://discussions.apple.com forums, especially if there is a forum specific to your topic, are a very good resource.

Save yourself some future pain, and just avoid Anti-Virus software and Mac cleaners. The volunteers spend a lot of time debugging system problems that are a result of these packages. macOS comes with its own defenses, and unless you are installing software from questionable sources, you are generally not going to experience malware on your Mac.

In addition to dialabrain's comment, you will also find numerous "transition to" books/articles/etc on the Internet These come in handy if you are already familiar with another operating system, like Windows or Linux, and want a quick start to learning how similar things work like with macOS.

Also, if you have an Apple Store near you, you can check to see what training offerings they may have. They provide either one-on-one or group settings and cover a number of topics for new Apple users.

What do you do with a personal computer. That might help with advice beyond Command-C vs Control-C, Command-V vs Control-V etc...

Tell us what you want to accomplish with your Mac and maybe some more targeted responses will appear.
