Mac OS X user interface theme editor for OS X 10.4-10.6.


Developer website: Geekspiff

Use ThemePark to create or modify the way Mac OS X looks, as well as to change the appearance of individual applications. Just draw titlebars, buttons, and other widgets in the graphics editor of your choice, and move them into ThemePark to create a new theme or modify an existing one. Also use ThemePark to create icon sets that can change every icon on your system, even common document icons.

With ThemePark, you can:

  • Create guiKits for use with Unsanity's ShapeShifter;
  • Create new themes or icon sets using your own graphics;
  • Merge your theme with an existing one to use it as a base or to make small tweaks to someone else's theme;
  • Quickly preview your theme while you're constructing it;
  • Easily find the element you're looking for using ThemePark's smart organization, filtering, and inline hints;
  • Save in-progress themes and easily see which areas you've already modified;
  • Edit resource files found inside of many applications;

What's New

Version 4.1:
  • Added transparent support for 10.6's modifications to the SArtFile.bin format. 10.5 files will be automatically converted and you can save to either format.
  • Added tagged copy/paste so you can copy arbitrary images one from one file and paste them into another without the element selection or the image sizes being identical.
  • Changes made to Extras.rsrc will now actually stick when you apply the theme.
  • Resolved an issue that could prevent a portion of an image from being editable.
  • Resolved an issue that caused scaled images to appear distorted. There's still more work to do here, though.
  • Resolved many issues that could arise when changing the size of an image.
