Couch Slouch allows your TV’s remote to control your Mac, and can also have your Mac and AV system react to one another, whether it’s having your Mac wake up when you switch on your TV or having your TV and AV receiver switch off when your Mac goes to sleep.
For a detailed overview of what Couch Slouch can do, check out the Features page!
Couch Slouch requires a TV (and AV reciever, if you have one) that is compatible with the CEC standard. For more information on compatibility, see the Compatibility page, and a Mac running Mac OS X 10.8 (Mountain Lion) or greater.
In addition, your Mac needs a compatible CEC-USB adapter, like the one made by Pulse Eight.
