A developer named watermark_hd has shipped Aqualink, a native SMB3 client for OS X Tiger and Leopard running on PowerPC Macs roughly 20 years old. The tool is built on Ronnie Sahlberg's libsmb2 library and routes connections through a local WebDAV server, letting Tiger's built-in mount_webdav mount remote volumes without any kernel extensions or hacks. Source code is on GitHub.
The practical payoff is real: aging PowerPC machines can now speak SMB3 to a modern NAS instead of falling back to SMB1 or going dark entirely. Older OS X versions that did ship SMB2 and SMB3 support were notoriously broken, forcing users back to CIFS, so Aqualink also patches a gap in machines that aren't even that old.
Read the full piece to understand the WebDAV relay architecture that makes this possible without modifying the OS, and why SMB3 support still doesn't solve the encrypted file share problem on these systems. The encryption ceiling is the next wall worth understanding.
