MacMost Q&A Forum • View All Forum Questions • Ask a Question 9/23/093:58 pm Smack Spaces has somebody heard about Smack spaces?, Can I use it in Macbook?, Is this apllication secure for mac?. Thanks — Emilio Comments: One Response to “Smack Spaces” Gary Rosenzweig 13 years ago I've head of it. For everyone else: It is a program that allows you to physically hit your MacBook on the side to make Spaces switch which Space you are viewing. Like Control+Arrow except that you are physically smacking the MacBook with your hand, and the accelerometers onboard are triggered. I haven't heard anything about it being secure or not -- not sure why that would be a security issue. I see it as a novelty, though, not something really useful.
