  • The “Quick Look” tab in the Preferences has been replaced with a new, more general “Folder Access” tab. It turns out that access to folders is useful not just for Quick Look, but also for other things (see the next item).
  • Chikoo is now more intelligent when attempting to locate files. For example, if Chikoo has access to the Dropbox folder on one Mac (—through the Folder Access Preferences; see the previous item—), the user will no longer be bothered about access to each file that is added to the library on another Mac.
  • Packages can now be imported. In other words, things like rtfd or OmniOutliner documents, which are not really files but package folders, can now be imported.
  • Read-only and locked files can now be imported.
  • File sizes now always match the ones shown in the Finder. Reason: Chikoo now also includes the sizes of resource forks. (But such a mismatch should have been rare in practice since most user files don’t have resource forks.)
  • The toolbar’s contextual menu is now also available in the View menu. This has its benefits. For example, users can now hide/show the toolbar using a keyboard shortcut if they assign one via the Keyboard System Preferences.
  • When a library window’s toolbar changes in height or is hidden/shown, the window’s height now stays the same. This makes toggling the toolbar more natural (see the previous item).
  • The Command-F keyboard shortcut and the Edit → Find menu item now bring focus to the search field (after showing the toolbar if it’s hidden).
  • Fixes a bug that makes it impossible to Control-click on a library window’s toolbar to bring up the contextual menu.


  • Completely rewritten from the ground up—requires OS X 10.10 or later.
  • Adds the ability to create multiple libraries.
  • Adds new columns and pane for various filesystem attributes (file name, path, size, date created, and date modified).
  • Adds the ability to import entire folders (i.e., import all files found when recursively traversing a given folder).
  • The “Chikoo folder” concept has been replaced by more general (and optional) “library folders.”
  • In smart lists, texts can now be filtered using more operators, including new length-based operators.
  • In smart lists, dates can now be compared against today’s date.
  • The built-in Name column can now be hidden.
  • Underlying extensions of type groups can now be more conveniently seen by moving the mouse over the Type column while holding down the Option key.
  • The name can now be synced to the file name, and vice versa.
  • Adds the ability to relocate multiple files at once based on their last known file names.
  • Libraries (i.e., the metadata) can now be located anywhere on the filesystem.
  • Support for the retina display Macs.
  • A brand new app icon.
  • Redesigned to look great on OS X Yosemite.
  • Chikoo now runs in sandbox mode, a security feature highly recommended by Apple for Mac apps.
  • A multitude of other improvements and bug fixes.


  • The app is now signed with a newer version of Developer ID so that it can be opened without warnings on the upcoming OS X 10.9.5 and OS X 10.10.


  • System requirements increased from 10.6 to 10.8.5 in preparation for an upcoming release.
  • The app is now signed with a Developer ID so that it can be opened without a warning from OS X.


  • Adds the ability to import files by dragging them directly on the Chikoo dock icon, on the Library, or on individual lists.
  • Adds the ability to copy attributes from one item and paste them on other items.
  • Fixes a bug that causes incorrect comparison of dates and numbers in smart lists.
  • Fixes various date picker glitches.
  • Contains various other bug fixes and enhancements.


  • A brand-new feature: The ability to see the filetypes of files. A new column has been added for the filetype. Users can furthermore create smart lists based on types, and even create their own type groups for maximum customization.
  • A few minor bug fixes.


  • Chikoo is no longer just a PDF organizer, but an organizer for any kind of file.
  • When importing, users can now leave files at their existing locations.


  • A ripe chikoo is spotted in the wilderness.
