multi channel audio from MC27 to Marantz SR-7007

I thought iMacs had USB connections as well.  What's the model number?

This adapter, that I linked to before, should work with a Thunderbolt connector:  https://www.amazon.com/Cable-Matters-DisplayPort-Adapter-Black/dp/B00DRK2ZIK

Regarding the Aux/Analog issue, you're getting your connectors confused.

Your Marantz has TWO connections named Aux.  One on the front (Aux1 which is analog) and one on the back (Aux2, which is HDMI).  That note in your manual is for Aux1.  If you plugged your HDMI cable into an Aux port, it was Aux2 on the back.

In fact, your Marantz duplicates the name for ALL its connections: there are 2 connections for each name (like DVD).  One is HDMI (digital) and one is RCA (analog).

Regardless of what you ever may think you read in your manual, HDMI is digital, and it is impossible for you to physically plug an HDMI cable into an analog connection.  So if you are using HDMI, you are using digital, not analog. Period.

I'd still like to hear the detail on that "not processed enough" error you said you were getting.

Yes my iMac does have USB 2 and 3 plugs. It's an iMac Retina 5K, 27-inch, Late 2015; 4 GHz Quad-Core Intel Core i7; MD Radeon R9 M395X 4 GB

I hope so, I ordered one.

Well, actually, the SR7007 AUX1 in the front is an HDMI plug (and whatever goes in there gets converted straight to analog. That's how I interpret the manual now). The AUX2 in the back needed to be manually assigned to HDMI in the AVR setup. Now the AUX2 connection works and accepts the Dolby Digital input from the MacBook and plays mch tracks. Previously, I was able to select PCM16 or 24 bit and LPCM 16 or 24 bit in DSP studio but these options don't exist anymore (not sure why. I reverted to .0.59 and the are gone there too). Only Dolby Digital and various DSD formats remain.

It was something like "Core Audio cannot convert the signal ... because the hardware is not capable ..."  I haven't been able to reproduce it since as I was going through a lot of different settings.  I believe this happened because I didn't select the HDMI for output but rather, the internal speakers were selected.

Thank you, wer

It's hard to tell, the manual is not very good, and there doesn't seem to be a useful diagram of the front; all the panel diagrams are very low-res; had to look at the promo photographs to be able to read the labels.  But if that's what they're doing with an HDMI port, it's a stupid useless thing to do. I'm surprised. But if they crippled the front connector, just don't use it.  Any of the other HDMI connectors should work properly I would think.

There are USB versions of HDMI adapters too; the question is did the new MacOS versions break them.

Yeah, I have a pretty good pdf version of the manual that came on a CD with the AVR. It does seem like a waste of a perfectly good HDMI input.

I was just looking up some. It's a bit confusing because some mention they will not work with MacOS. I found one that states MacOS compatibility
https://www.amazon.com/StarTech-com-External-Monitor-Graphics-Adapter/dp/B00OD37KHG
but also says stereo audio, and I definitely want mch. I might give it a try and RMA it if it doesn't do mch.

There's multiple versions of that one, the "Standard" version says it does 5.1.  That's one of the ones I think I linked to before.
