Latest version of rsync

The default /usr/bin/rsync on macOS Sonoma vs macOS Sequoia and macOS Tahoe differ in their versions. All versions adhere to protocol 29 of version 2.6.9, but the licenses for these versions are distinct. Additionally, there may be variations in the code. In macOS Sonoma, the default version is version 2.6.9, released in November 2006. In macOS Sequoia and macOS Tahoe, the default version is a compatible rsync based on the BSD license. The command /usr/bin/rsync --version in macOS Sequoia and macOS Tahoe displays openrsync: protocol version 29, rsync version 2.6.9 compatible.

It is recommended to install the latest release of rsync by Homebrew. Install the latest version by command:

brew install rsync

In RsyncUI, navigate to the settings menu and select Rsync and path. If rsync is installed via Homebrew, simply tick the boxes for Rsync ver3.x and ensure that RsyncUI correctly sets the path for rsync.

Note: RsyncUI supports snapshots of files and syncremote. However, due to a bug in version 2.6.9 of rsync, the snapshot and syncremote feature in RsyncUI requires the installation of the latest version of rsync.
