macOS Mail Signature Installer

Easily install HTML signatures in macOS’s Mail application.

Usage

Pipe your signature file into install-signature.sh and pass the desired name of your signature as the first argument, for example:

$ cat my-signature.html | ./install-signature.sh "My Signature"

Not using iCloud Drive

If you’re not using iCloud Drive and are running macOS Mojave or later, the script won’t be able to access your Mail signatures due to new security protections. You’re able to work around this by granting Terminal full disk access, however, this is not recommended as a permanent solution.
