Jonas has made a list of the OS X applications he normally uses.
I would add at least:
- SSHKeychain for loading ssh keys via the keychain. I’m not sure how I would survive without it.
- Fugu an SFTP client which together with SSHKeychain makes it a piece of cake to edit and handle remote files in a secure way.
I’m still missing a tool to make URLs in a Term.app terminal window clickable so the URL would be opened in Safari.
