ScreenFlow Telestream Audio Driver not installing on High Sierra

Hi -

New user of ScreenFlow 7.1 (29890) here, and so far I'm not impressed. I'm running High Sierra on an iMac, and the Telestream audio driver isn't installing. Any time I try to record, I get the error message "Computer audio connection not found - Please reinstall the ScreenFlow audio driver through the ScreenFlow Preferences". I've tried that multiple times, even restarting the iMac after installing.

The installer completes the installation (see attached screenshot), but it's obvious that it isn't actually been installed as the driver .kext file does not appear in the Extensions folder. Most other apps with extensions have been telling me to approve the extension in System Preferences > Extensions, but the audio driver isn't even appearing in the list. 

My equipment specs:

Hardware Overview:

  Model Name:    iMac
  Model Identifier:    iMac17,1
  Processor Name:    Intel Core i7
  Processor Speed:    4 GHz
  Number of Processors:    1
  Total Number of Cores:    4
  L2 Cache (per Core):    256 KB
  L3 Cache:    8 MB
  Memory:    16 GB
  Boot ROM Version:    IM171.0110.B00
  SMC Version (system):    2.34f2

 

Just noticed that the driver is showing up as disabled because "No User Consent" has been given. See second screenshot that is showing that net.telestream.driver.TelestreamAudio isn't installed. Like I said earlier, most extensions have been asking for me to enable; this one never did and it's apparent that it's not set up to even ask for user consent. 

Are you sure you tested ScreenFlow under High Sierra?

     Yes and many of us are using it every day.

     Make sure you're installing on an Admin account. Given your second screenshot something is blocking other similar drivers as well. It's possible a third party driver is also impacting the install. Please remove programs like Sound Flower and similar audio driver based capture software.

    CraigS Hi, Craig, and thanks for the response.

    As you'd expect, I recently upgraded this Mac to macOS High Sierra and I had done a clean install. There were no other third-party drivers installed. However, just about the same time that you responded, a developer friend of mine who had seen the same issue with ScreenFlow & High Sierra sent along the screenshot that's attached. 

    What worked -- and it also ended up installing those two other Parallels drivers -- was trying the installation once again while keeping System Preferences > Security and Privacy open. It displayed the message shown in the screenshot (except it said "developer TeleStream") and I was finally able to allow the driver to install.

    Steve Sande True, the OS security settings can block certain things like third party extension entirely. Glad you found it.

    David Archery was it resolved by using Allow in Security & Privacy? Your last jpeg shows success but I don't see the Allow button.

    I'm not impressed either although it has enabled me to make many videos and perform moderately well for last year or so, but I never know when it will crash, why or how much of my file will be saved.  I waste about 2 to 3 hours per week with spurious crashes, redoing my edits, etc. ad nauseam.  I have a MAC mini and have posted all the particulars here before, but he problem has never been identified and thus cannot be solved.  Permanent limp mode is the lot perhaps of many Screenflow users.

    D Hunt If you reported the issue using our form you'd have a case number. You should be able to follow up with that number and ask for a status update. 
    The issue in this thread is specific to Apple's own security changes in High Sierra which may itself have issues not specific to ScreenFlow.

  • CraigS in my case the 'allow' button didn't show and I found this solution elsewhere on this forum, which worked for me

    Peter Comeau Yes so it seems it can be fixed in Terminal but that also indicates an issue with how macOS is behaving since it isn't offering an option its supposed to.

    Please do fill out the form and report what you needed to do to fix it. We may need to bring this up with Apple.

    Thanks for posting the fix. This was driving my crazy on my new macbook pro running 10.13.3 High Sierra.

    Hey Craig... Please add this instruction and screenshots to this page: http://dynamic.telestream.net/downloads/download-screenflow-audio.asp

    That way others using screenflow on a new mac with 10.13 High Sierra  wont run into this too.

    Dr Dan Although I think in this case it was that the Allow button was not present once the driver was installed. Installing the driver itself is not sufficient which is what the page you link to resolves. High Sierra requires and extra step.
