WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!

I'm trying to connect to a raspberry pi with ssh. I've had to reformat the sd card on the pi and now the Mac wont allow connection.


IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!


Someone could be eavesdropping on you right now (man-in-the-middle attack)!


It is also possible that a host key has just been changed.


The fingerprint for the ECDSA key sent by the remote host is


SHA256:RAtwcZ/adqxqcs1M2sZrI5The6XOaC+1MrwtkqHkB/o.


Please contact your system administrator.


Add correct host key in /Users/Adrian 1/.ssh/known_hosts to get rid of this message.


Offending ECDSA key in /Users/Adrian 1/.ssh/known_hosts:12


ECDSA host key for climate.local has changed and you have requested strict checking.


Host key verification failed.



How do I get to edit the known_hosts list?



Mac mini, macOS 10.15
