Non-imac Pro audio Driver in 7.3?

In 7.3, you guys changed the audio driver to support the new iMac Pros out there.  Some of us still use old hardware (I'm on a 2011 imac 27" 3.4ghz) and the previous audio driver (included in 7.2) was much better: 

a) it never crashed after recording my screen using Logic Pro 10.4.1

b) Logic didn't prompt me to switch audio devices AFTER screen recording has begun.  This is annoying because if I'm trying to shoot a video of a large session with lots of audio units being loaded, they all have to reload first before I can play the session. 

Can you guys release an update that checks the hardware the audio driver is being installed on, and if the computer is *NOT* an iMac Pro, install the 7.2 driver instead of the iMac Pro-compatible 7.3 driver?

    You can go to the Linked Page and download 7.2 under Previous Versions at the top of the page.

    For various reasons including changes being made by Apple we're going to have to go with the new driver going forward. There will be updates to improve ease of use.

  • CraigS  ok, so maybe make the driver check the hardware version directly and use the old 7.2 driver code (compiled into the 7.3 driver binary) if the computer isn't an iMac Pro.  Let me know if you need a beta tester!

    Charles Schiermeyer Changes being made by Apple (OS changes) would mean we have to move to the new driver for all systems. Changes going forward from 7.3 will be with the new driver.

  • CraigS as a software developer myself, I know that it's possible to detect what platform type the driver is being used on and provide the appropriate platform code accordingly IN THE SAME DRIVER FILE.  I'm merely suggesting that you guys add that ability to the driver for older computers running fairly recent OS's (10.12.x).   I don't have an iMac Pro or 2017+ macBook pro and I'm not planning on getting one any time soon.   It's probably trivial for your software engineers to add some 

    if( SystemStats::getHardwareVersion != APPLE_IMAC_PRO )
    { /* use old driver code */ }
    else
    { /* use new driver code */ }


    lines to your audio driver when it's loaded in memory.  that's all I'm saying...

    Charles Schiermeyer Apple does not want developers to use the old driver type. If you want that driver you can install ScreenFlow 7.2 and then install 7.3. We're not making the old driver available with current and future versions of ScreenFlow. We follow Apple's guidance and rules as a developer.
