Cloud accounts · FTP and SFTP servers
Can I use another Mac as an SFTP destination?
Short answer: Yes. Turn on Remote Login on the other Mac (System Settings, General, Sharing), then add it as an SFTP account with its address, port 22 and a user's password or key. Two Macs running Storage Studio can also use Bridge.
Yes. On the other Mac, turn on Remote Login in System Settings → General → Sharing, and note its address and the user you'll sign in as. Then add it in Storage Studio as an SFTP account with that address, port 22 and that user's password or key.
If both Macs run Storage Studio, you may prefer Bridge, which links your own devices directly, or Collab Sync to keep a folder mirrored on both — see Bridge devices.
