Thanks mas.to/@Cykelero!

Kaleidoscope 6.0 just got smarter! Collapse unchanged text blocks for faster, cleaner comparisons. Focus on what really matters — the differences.

Also new in Kaleidoscope 5.3: quickly compare any branch against the current working copy.

Want to see a git commit history right in Kaleidoscope? Simply update to version 5.3!

When looking at the commit history of a file, Navigate > File History > Select Previous A & B and … Select Next A & B let you browse changes one by one. Use shortcuts ⌃[ and ⌃] to navigate without taking your fingers off the keyboard.

Did you know that you can quickly preview any file in a Folder Comparison or Changeset by pressing space or selecting View > Quick Look ⌘Y?

Whenever you spot a (short) git commit hash anywhere on your system, even on a web page, just open the changeset of that commit in Kaleidoscope from the service menu.

Did you accidentally open a branch comparison in the wrong order? No worries! Just right-click on the row in Recents and select ‘Open Inverted’.

In File Properties, you’ll find all the data except for the actual content. Even Extended Attributes and the presence of a BOM in UTF-8 files are included.

Want to know the exact file size of an item in a folder comparison? Just hover over the size shown and you’ll get a tooltip with the byte size. It works for the date modified too. And guess what? Folders also show you the total size of their contents.

When you see a commit hash in Kaleidoscope, you can pop up a menu with handy commands like copying the hash, checking out the full details, or opening the commit in your source service.

In a text document, quickly jump to a specific line using the keyboard shortcut ⌘L (or Navigate > Jump to Line). Since Kaleidoscope has multiple editors, you’ll need a way to select which editor you want to jump to. In addition to the buttons, you can also use ⌘◀ or ⌘A to select side A, and so on.

It's a great honor to once again be included in Brett's Favorite macOS Apps this year, alongside some of our own heroes. Thank you @ttscoff.bsky.social for the recognition! 🙌

Want to be the first to check out new features in Kaleidoscope 5.3? Like the ability to compare directly with the working copy. And much more… Just set Software Update to Include Beta Versions. Merry Christmas!
