GrabAll for Mac
GrabAll is a free and minimalist Mac OS X application that is capable of taking a screenshot of all active windows on your screen, of all the icons in the menu bar, the Dock and the desktop icons with only one mouse click.
The utility lives on your menu bar and provides a dark icon that opens a simple menu when clicked. Before being able to use GrabAll, you will need to specify the folder to which all the snapshots should go to.
Furthermore, after specifying the output folder, you have 2 options: grabbing snapshots without delays or grabbing screenshots 3 seconds after clicking the option. A nice advantage is the ability to use keyboard shortcuts (Shift + CMD + ‘+’ and CTRL + Shift + CMD + ‘+’, respectively).
GrabAll captures the screenshots in just a few seconds. Also, in the process, the screen will flash until all the snapshots are taken. Speaking of which, GrabAll puts the images (PNGs) into an automatically generated folder (named after the date and time) placed into a “GrabAll” folder created in the selected location.
Another interesting feature is that GrabAll captures all active windows (only from the current screen, though) and the icons of active apps in the system bar, as well as the Dock. The created snapshots are named after the program they represent and include the process ID in brackets.
Taking everything into consideration, the GrabAll tool is nothing fancy, but it does what it advertises. The app is extremely easy to use and captures screenshots of active elements on your screen very quickly.
