Latest version of rsync

The default /usr/bin/rsync differs between macOS versions:

• macOS Sonoma: Uses rsync version 2.6.9 (released November 2006)
• macOS Sequoia and Tahoe: Use openrsync, a BSD-licensed implementation compatible with rsync protocol 29 and version 2.6.9

Installing rsync via Homebrew

Install the latest version using Homebrew:

brew install rsync

After installation, configure RsyncUI:

1. Navigate to Settings and select Rsync and path
2. Enable Rsync ver3.x
3. RsyncUI will automatically set the correct path

Note: RsyncUI’s snapshot and sync remote features require rsync version 3.x due to limitations in version 2.6.9.
