“ssh: handshake failed” on a mac

[garnertb]

Posting this in case any one else runs into it.

Could not clone from the remote: ssh: handshake failed: ssh: unable to authenticate, attempted methods [none publickey], no supported methods remain:

When configured to use ssh-auth for cloning, on a mac, I got this error initially, which was surprising since git works fine.

The fix was to add my ssh key the ssh-agent. The relevant step from our docs was this:

ssh-add --apple-use-keychain ~/.ssh/id_ed25519
