Unison For Mac

The Unison file synchronizer macOS application offers you the possibility to quickly synchronize the contents of two folders, while providing extensive control over the synchronization direction for each specific file.

The best part is that Unison can create exact replicas of a certain folder on a different drive connected to your Mac, or in a remote location. This way, you can work on a set of files, while making sure the originals are backed up to a different location, and choose to mirror the changes with minimal effort.

Unison comes with a minimalist graphical user interface, but can also install a command line tool which will prove to be useful if you need to sync files to a remote location. In the Unison main window you get to define an unlimited number of folder pairs which you will be able to synchronize faster.

Note that you will have to use the Unison Rescan feature for the app to detect the changes in the root folders. The next step is to setup the synchronization direction and manually start the transfer.

If a certain file has been updated in both root folders, but the content is not identical, Unison points out the conflict, which will have to be resolved by the user. However, Unison can automatically handle non conflicting files, and even resolves “false conflicts” on its own.

Unison is a great tool to have around if you want to simplify the synchronization of two directories, including their subfolders, while having extensive control over the process. The app enables you to decide the sync direction for each file, identifies possible conflicts, and enables you to decide what to do.
