Hey! Does anyone happen to have a driver for the Symphony I/O MK I for Mac OS 10.13?

It's not available on their website, I've emailed with Apogee and while they were initially helpful, I haven't heard from them in 4 or 5 days so now I'm turning to you, fellow GearSpacers, to see if anyone's got this DMG file laying around.

I'm wanting to use the Symphony in USB Mode - I have Maestro 2 and after installing the 5.4c software (which is rated for OS 10.15 - and yes, I ran the installer twice as the instructions say to do), Maestro did recognize the unit but there's still a perpetual exclamation mark on it and it will not play music from a WAV file, youtube, or ProTools.

I've tried hardware resetting, powercycling, the whole 9 yards.

Hope someone can help! Would love to get to making music with this thing ASAP.
