With the recent update to Airfoil 4, along with the many changes to Apple’s AirPlay (formerly AirTunes) protocol, we’ve received lots of questions. We hope this Q&A will answer the most common among them.

Q: What version of Mac OS X does Airfoil require?

A: Airfoil 4 requires Mac OS X 10.6 (Snow Leopard).

If you’re still on Mac OS X 10.5 (Leopard) or even Mac OS X 10.4 (Tiger), see this page for information on version of Airfoil for your OS.

Q: What’s the upgrade fee for Airfoil 4?

A: Airfoil 4 is a $10 paid upgrade from all older versions of Airfoil. You can upgrade right through this form.

Q: What if I recently purchased Airfoil?

A: If you purchased after November 1st, 2010 (your license key will start with KUTA-), you already own a license key for Airfoil 4. Just download it and enjoy!

Q: Will Airfoil Speakers on other platforms be updated?

A: For now, the new features in Airfoil Speakers for Mac are exclusive to the Mac. However, they’ll show up on other platforms in 2011, including Airfoil Speakers for Windows and Airfoil Speakers Touch for iOS.

Q: Will there be updates for Airfoil for Windows?

A: Airfoil for Windows is a separate product from Airfoil for Mac, and it follows its own development schedule. We do hope to bring many of the improvements seen in the Mac version to Windows in the future.

Q: What about Airfoil Speakers for <my favorite platform>?

A: We’ll be considering versions for other platforms, such as Android. You can always see all currently available versions here.

Q: Can you help me send video from my Mac to my Apple TV?

A: AirPlay for video has just been released by Apple, and currently works only with iTunes on the Mac. We’re investigating this, so stay tuned!

Q: What local video files can I play in Airfoil Video Player?

A: Airfoil Video Player uses QuickTime to play video, so as long as QuickTime supports it, you can play it. With QuickTime and QuickTime plugins like Perian (already included with Airfoil Video Player), nearly all video formats are supported.

Q: Which websites work with Airfoil Video Player’s new Web mode?

A: Airfoil Video Player can play QuickTime, Flash, and Silverlight web video in sync with remote audio, so it should work with nearly all video sites. If you find a site that doesn’t work, please let us know and we’ll take a look.

Q: Can Airfoil Video Player play my iTunes video purchases?

A: Due to Apple’s FairPlay DRM, Airfoil Video Player can’t open these video files. Unfortunately, it won’t be possible to support iTunes video until the DRM is dropped by Apple.

Q: What if I still have a question?

A: For the fastest answers, check out the Airfoil manual (under the Help menu), as well as our Knowledge Base. If you can’t find what you need there though, please get in touch.
