Problem with Terminal after running `chsh -s /bin/zsh`
Logged into Terminal to make a change to Preview's Scaling as defaults write com.apple.Preview PVImagePrintingScaleMode -bool FALSE
from Mac KungFu https://www.mackungfu.org/turn-of-preview-s-scaling-when-printing. Was told in Terminal that "The default interactive shell is now zsh. To update your account is use zsh, please run `chsh -s /bin/zsh`. When I entered that code in Terminal it responded with "Changing shell for normand." Followed by "Password for normand:" and a key symbol. I am unable to enter anything after that, so I cannot enter my password. I selected the key symbol and hi return. I was then given this:
chsh: Credentials could not be verified, user name or password is invalid. Credentials could not be verified, user name or password is invalid." followed by "iMac2020:~ normand$" I tried entering my password after that and got: "-bash: (my password): command not found
iMac2020:~ normand$ "
Not sure where to go from here. Help needed.
