The releases of Mac OS X 10.10 (Yosemite) and Mac OS X 10.9 (Mavericks) have led to some big changes under the hood for Piezo, on all versions of Mac OS X. Most users should notice no differences in their day-to-day usage of Piezo. However, these changes are significant, so we've highlighted some differences you might see below.

## Audio Capture

### Basics

Piezo's audio capture engine has been overhauled for current compatibility as well as future improvements. If Piezo no longer works with an audio source as you desire, please contact us via the Support form found in Piezo's Help menu.

### Capturing Audio From Safari, FaceTime, or Messages

Unfortunately, due to underlying changes made by Apple, capturing audio from Safari, FaceTime, or Message is no longer possible with Piezo.

To capture web-based audio, you'll want to use another browser as your source in Piezo. We recommend Google Chrome or Firefox. Use one of those browsers as your source in Piezo, and you'll be able to record web-based audio.

If capturing audio specifically from Safari, FaceTime, or Messages is a requirement, you can take a look at Audio Hijack. It offers more powerful audio capture and is able to record from these sources, thanks to its optional Instant On component.
