What's New in Version 4
macOS Version
At long last, Beyond Compare runs natively on Macs!
BC for Mac has all the power and functionality you've come to expect from Beyond Compare, now with native look and feel, speed, and enhancements to make it feel at home.
New Home View
The new Home View adds session search and web resources. The layout is easier to manage with on-screen controls.
And, we think it's prettier too!
3-way Folder Merge 
Three-way merging now extends to folders. Compare independent changes against a common ancestor to quickly merge your changes with someone else's. It makes merging your customizations into a new release a snap.
Ad Hoc Unimportant Text
It is now easier to define unimportant text in your Text Compares. Define unimportant terms directly from the Rules dialog, rather than having to edit your file formats.
WebDAV, Amazon S3, Subversion, Dropbox and OneDrive Support
In addition to FTP, you can access WebDAV resources, Amazon S3 buckets, Subversion repositories, Dropbox's cloud storage, and Microsoft OneDrive directly from within Beyond Compare. Organize your remote service profiles with friendly names and folder hierarchies.
Overhauled Picture Compare
Picture Compare has a new look, with automatic zoom, pixel-level details, and simplified controls. Tolerance comparison mode uses grayscale to reveal the image along with the differences. It's also faster, uses less memory, and supports additional image formats.
Overhauled Preferences Dialog with Search
The reorganized options dialog includes a search feature for finding specific settings quickly. Commands for all comparison types can be customized without first having to open a view.
