Problem with Terminal Utility
After updating to Catalina 10.15.4, I was having instability problems and I tried to create a bootable external HD to run Mojave. Somehow I got it wrong when trying to follow the instructions found here:
https://9to5mac.com/2018/06/18/how-to-create-a-bootable-macos-mojave-10-14-usb-install-drive-video/
I now have the message in terminal:
"The default interactive shell is now zsh.
To update your account to use zsh, please run `chsh -s /bin/zsh`.
For more details, please visit https://support.apple.com/kb/HT208050."
What does this mean and what do I have to do?
