Mac OS X contains a number of useful utilities that can enhance creative workflows. In the root-level folder /Library/Scripts/ColorSync are editable AppleScript utilities that perform various common design tasks.
Say, for example, you have a collection of images in a directory that you would like to prepare for the web by embedding the sRGB color profile. Rather than open the images individually to assign the profile, you could use the "Embed chosen profile" script instead by simply dragging-and-dropping your collection of images on that script's icon in the Colorsync folder. A real time-saver when dealing with hundreds of images. And, because these scripts are editable, you can customize them to be specific to your workflow needs.
