Can't record computer audio Mac OS High Sierra Screenflow 6.2.3

No matter what I do I can't get Screenflow 6.2.3 to record computer audio under Mac OS High Sierra. I get the 'install Screenflow audio driver' dialog. I run the installer, it completes OK, but still I get the error shown. Doesn't matter if I reboot, doesn't matter how many time I do it. It only works if I disable SIP and I don't want to do that. Screenflow 7 is the same.

Can you suggest a solution?

    It's possible there is a third party driver blocking ScreenFlow's driver. Do you have A DAW or any third party software that might install an audio driver?

     

    Apple's SIP shouldn't block ScreenFlow's audio driver from installing.


    When you go to ScreenFlow Preferences next to audio driver does it say Install or Uninstall. If it says Install than it's not installing (perhaps SIP is blocking it)

    Also make sure you are in an Admin account when installing the driver (perhaps SIP is affecting an attempted install from a non admin account).

    Thanks for the reply.

    I think I solved it: I manually deleted the kext from HD > Library > Extensions and let Screenflow re-install it. Now it seems fine. There is also a copy of the kext at HD > Library > StagedExtensions > Library > Extensions that can only be deleted if SIP is disabled. Should it be there?

  • I have the same problem. I have a MacOS High Sierra with the latest update 10.12.6. Have just installed trial version of Screenflow 7.1. What kext did you remove? I'm not an expert and there were plenty to pick from... ;)

     10.12.6 is Sierra. macOS High Sierra is 10.13.1.

    Current version of ScreenFlow is 7.1.1 so you should install that.

    High Sierra has new security features (referred to as SIP) which may sometimes require going into System Preferences > Security & Privacy > General and selecting "Allow" if it blocks the installing of TelestreamAudio sound driver.

  • CraigS Hi. Sierra 10.13.1/Screenflow Version 7.1.1 can't get the audio driver installed. Have tried everything suggested above. Any other ideas? Clicking "Allow" in S&P doesn't seem to do anything. Have reinstalled, rebooted, etc.

    John Healy You can try the steps Ax Max suggests in his post I linked to.

  • Having the same issue with Voila, Capto and Screen Record-Screen Recorder apps. In their own way, each app prompts to install audio component. Which has been done several times with Voila and Capto. Yet, the same prompt occurs.  An earlier comment mentioned deleting "kexts".  Deleted kext from HD > Library > Extensions. Yet, does not give option to delete kext from HD > Library > StageExtensions > Library.  All of this is new to me.  Any resolutions is greatly appreciated!

    Wade Hampton If you are on High Sierra you need to grant permission to install drivers. See this FAQ.

  • Resolved. I went to System Preferences > General > Allowed (certain software for unblocking/blocking). Thanks for your quick reply!

    Wade Hampton You're welcome of course. High Sierra's new security does add steps to installing third party drivers. It's easy to miss.
