CDSDAudioCaptureSupport.kext “file was installed improperly and cannot be used.

This error message is there because you have a copy of Spin Doctor loaded on your computer.  No, this doesn’t mean that you have a gentlemen in a brown coat, breakdancing in your computer…  I mean the Roxio software, that is suppose to assist with capturing digital audio.

Then launch Spin Doctor and select “Install Audio Capture Support” from the CD Spin Doctor menu. This updates the kext file (located in the /System/Library/Extensions folder) to a version that is compatible with Snow Leopard.

The kext file itself is required if you want to use CD Spin Doctor’s “Audio Music Capture” option. This allows you to “instantly” start recording whatever audio is currently playing on your Mac.
