GifGrabber Captures Your Mac’s Screen and Creates Animated GIFs
OS X: Animated GIFs visually convey your point of view without using video. You can create animated GIFs from an existing video, but if you just want to take a screenshot, GifGrabber will do the trick.
GifGrabber is similar to the previously presented Giffing tool , but for Mac. After launching the program, draw a frame on the screen and press record. You can also start and stop capturing with hotkeys to keep your mouse out of the way. The program does simple cropping and compressing the file, and you have a GIF that you can share wherever you want.
