The default interactive shell is now zsh

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.

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

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.

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

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

What's the point of directing to a page that's useless.... waste of time

What's the point of making a post that doesn't ask or answer a technical support question?

Seems like more of a waste of time.

I looked at all of the links on this thread and they all seem helpful to me. What was useless about the link you visited?

How did I get here did you ask??.....I am trying to determine how to fix an Apple screw up...all Video conferencing software including Apple's Facetime, on my Apple Macbook Pro won't recognize the camera at a time when video conferencing is a necessity. The system shows a Facetime camera, but the system does not recognize it. As a fix, another Apple forum pointed me to this set of instructions without any explanations...just do this. Why I am here or why any user should care about the 'shell' or any shell in any software system is absurd, particularly given the price of any Apple product.

That doesn't explain how you ended up here in this thread. Changing your default Shell has nothing to do with any of those problems.

Go to the Top of the page and select Discussion from the Post menu.

Start your own question so you can get help with your specific problem.

Are you an Apple Customer support person?

Nobody here is an Apple Customer Support person.

The default interactive shell is now zsh I have just updated my software to Catalina and my security software is not opening.

Well, that would be a good thing. Any "security" software not part of the OS is part of the problem.

And, it has nothing to do with the default shell.
