How can I keep YouTube playing the video while the screen is on sleep on my MacBook Air?
No, I haven't. How does it work?
Caffeine is a simple app that prevents your MacBook Air from going to sleep, dimming the screen or starting the screensaver. You can download the app for free from the Mac App Store, launch it and click on the "Caffeine cup" icon in the menu bar to activate it. This should keep your YouTube video playing even if your MacBook Air goes to sleep.
