The default interactive shell is now zsh

If you do not wish to use Terminal open https://support.apple.com/kb/HT208050 and follow the instructions for using System Preferences

what is this and do I need to run something if so how do I do that

If you don't use the Terminal, you don't have to do anything.

If you user Terminal, then it is suggesting you switch to zsh instead of bash.

You don't have to switch to zsh. You can continue to use bash. Bash is old and unsupported by Apple, so zsh might be a better choice.

If you want to switch to zsh, copy the entire command, including the back-tics (`) and paste it into Terminal exactly as the message states. There is nothing more to do.

Yes, you can start with answering: What is zsh?

The Z Shell. Search for Unix Shell and you can find much more information.

There are many unix shell scripting environments, such as the Bourne Shell (sh), the Bourne Again Shell (bash), the C shell (csh), and several others.

For a long time now, macOS has defaulted to bash. Since the current bash is licensed under GPL v3, Apple cannot update it and distribute it on macOS. So, they have switched the default shell to Z shell which is backward compatible with bash and is licensed under GPL v2.

As Lurkums said, if you don't know what it is, you don't need to do anything, or you can run the command so that if you ever use Terminal, you'll be using zsh instead of bash.

There seems to be a lot of people making a large fuss about nothing.

Open TERMINAL

Paste into it

chsh -s /bin/zsh

Press enter

Choose Apple menu >system preferences >user and groups click the lock, type password then 'CTRL + click' on user name on the left, click on popup advance options. Choose a shell from 'login shell' menu, then click ok to save the changes. Hopes helped.

keystrokes are not echoed in terminal. Type your password then hit return.

You don't need to change your default shell to run the command. There are many shells. You can use any of them.

It’s just a different shell. A shell is the interactive environment for using the Unix backbone.

You don’t have to use it if you don’t want to.

There are several other shells, too

I was prompted to this site in order to run a different system, whatever that means.

Whatever it is you need please start a different thread. Read Writing an effective Apple Support Communities question first please

No-one has any particular opinions. Apple just made change. If you want it, change to it. If you don't want it, don't change to it. I prefer to use their recommendation, you may or may not. Flip a coin.

Do you have a question about the switch to zsh?

I have received notice from apple to log in to this site. "The default interactive shell is now zsh." Now what do I do?

how can I update my account to ZSH How to run chsh -s /bin/zsh`.

I won't have to use the old shekk sudo ..... but I'll have to open chsh -s ... Thanks

It genuinely does not matter. If you do not use Terminal then do not bother. Or bother. It will make no difference to you either way
