When you run the 'build.rb' script it builds the project with Xcode and then runs the 'load.rb' script automatically. In the Soundflower 'Tools' folder there is a Ruby script called 'load.rb' which will copy the built kext into the install location using sudo. and applescript dialog) to finish a build.

Instead I have found a new piece of wonderful software called Voila ( was provided an affiliate link to use from Global Delight). It isn’t free unfortunately, but for $10, the amount of hassle you save is worth it. One of the feature that it includes is the ability to capture computer audio without using the SoundFlower trick below which is very convenient. So I was looking for a software to capture my computer screen on Mac OSX and was surprised that the newest QuickTime (version 10) comes with a screen recording feature. It can record both your entire screen or or just a selected area, thought there appears to be a minimum height/width it requires. It encodes the video in H.264 and audio in AAC, both which are excellent and widely supported codecs. I’m not sure if these are changeable or configurable, but worse case you can easily re-encode it afterwards. One caveat of using QuickTime (or just about any screen recording software) is that there isn’t a easy way to record the computer audio. Some soundcards come with drivers that has an input that is the computer audio output, but Mac by default doesn’t. QuickTime will allow you to record from line-in, so if wanted, you can purchase a short 3.5mm mini-stereo cable and connect your audio output to audio input. Go to System Preferences > Sound and see if the new outputs exist: Soundflower (2ch) and Soundflower (16ch).You can download the latest version from ( Soundflower homepage) Instructions for enabling Sunflower (computer audio): I did a little search online and found an interesting software called Soundflower by Cycling 74 and basically what it does is that it loops the audio back into the computer as an input, allowing QuickTime and any other software to record the computer audio. ![]() ![]() Select Soundflower (2ch) as your output.If not, you may need to restart your computer. ![]() Audio should have stopped coming out of your speakers/headphones.2 channels/stereo should be sufficient in most scenarios, but feel free to use the 16 channels one.
