A very common "doh!" is you copied over the relevant item in Keychain,

BUT!

you forgot the private key part:

So fi the disclosure triangle on the left is missing and the "key" symbol part is missing, that's what's happened.

Solution: just EXPAND the triangle and highlight BOTH parts, then click export. move the file to your other Mac and open.

ALSO -- don't forget, in Xcode you have to literally login these days.

Xcode - Preferences - second tab == Accounts

It's easy to forget, say, one of your various client's accounts there.
