What’s New:

Version 3.7.0


  • Sharing You can now share any text diff using the familiar and convenient Share button in the window toolbar. Choose from functionality provided by macOS to directly share via AirDrop, Mail, Messages, or open a comparison in Notes. You can also choose to share via Share Menu extensions provided by the other apps you use. Kaleidoscope converts your diff into a HTML document in those cases.
  • Save a Patch File. Kaleidoscope now has the ability to write a text diff to a standard patch file, which is also accessible via the Share button.
  • There’s now a preference setting to disable JSON normalization by default, if the functionality doesn’t suit your workflow. When disabled, you can still enable it when needed from the bottom toolbar.
  • Kaleidoscope now enables you to modify a comparison that contains normalized JSON, after confirming this is what you want. It also offers to switch to the non-normalized variant.
  • The File Shelf offers an option to save temporary content (such as imported from the Clipboard, ksdiff, Services or Shortcuts) to a file.


  • The Find functionality is now also available for single documents (such as added or removed files in a changeset).
  • The processing icon in the bottom toolbar (JSON normalization) is more prominent when turned on.
  • The backspace character is now also being treated as invisible character, and shown accordingly.
  • The JSON normalization will no longer quote slash (/) characters. We were surprised ourselves that it is defined with a quoted slash in the JSON standard.


  • Various fixes to the Find functionality
  • When installing a license via double-clicking a license file, a potential Trial Expired dialog will now correctly disappear.
  • Moving a window between screens no longer results in occasional unintended size changes.
  • Several fixes to the Open Recent menu. You may need to get rid of corrupted old entries by cleaning it once after installation.
