Those of you in the Diablo 3 Beta may be wondering where the game is storing all of your beautiful screenshots, because there is no included screenshots folder located in the Diablo 3 directory.
Here’s where you can find them:
Windows Diablo 3 Screenshots Folder
C:\Users\Your Name\Documents\Diablo III\Screenshots
Mac OS X Diablo 3 Screenshots Folder
user\Library\Application Support\Blizzard\Diablo III\Screenshots
Locating the Diablo 3 screenshots folder on OSX Lion and Mountain Lion requires an extra step. See this post for more info.
Taking a screenshot on a Mac
The default keybind for taking screenshots on a Mac is F13. This obviously poses a problem for users who are gaming on a laptop or mini keyboard, as there is no F13 key.
It’s an easy fix, however, so just open up the game’s Options menu and select the Key Bindings tab on the left. Scroll down to System > Take a Screenshot, click on either Key Binding tab, input your desired screenshot key and click Apply.
Cant get it to work on my Macbook Pro 🙁
