RsyncUI and RsyncOSX are GUI´s on the Apple macOS platform for the command line tool rsync. The main difference between the two apps is how the User Interface (UI) is built. It is rsync which executes the synchronize data tasks in both apps. The GUI´s are only for organizing tasks, setting parameters to rsync and make it easier to use rsync. If you are on macOS Sonoma use RsyncUI. RsyncUI is under active development.

Both apps might be installed by Homebrew or by direct Download. The apps are signed and notarized by Apple.

The development of RsyncOSX commenced in 2015 as a private project to learn Swift. In 2019, Apple released SwiftUI, which is a development framework for building user interfaces for iOS, iPadOS, watchOS, TVOS, and macOS. SwiftUI quickly became very popular and I commence another private project to learn SwiftUI. The model part of RsyncOSX was at that time quite stable, and I decided to refactor the GUI by SwiftUI. And that is the short story behind the two applications.

The UI of RsyncUI and RsyncOSX can for users who dont know rsync be difficult and complex to understand. Setting wrong parameters to rsync can result in deleted data.RsyncUI nor RsyncOSX will not stop you for doing so. That is why it is very important to execute a simulated run, a --dry-run, and verify the result before the real run.

Please be aware it is an external task not controlled by RsyncUI or RsyncOSX, which executes the command-line tool rsync. The progress and termination of the external rsync task are monitored. The user can abort the task at any time. Please let the abort finish and cleanup properly before starting a new task. It might take a few seconds. If not, the apps might become unresponsive.
