I'm in exactly the same boat.  If I could run an Apple Native AU plugin in the DAW (Logic for me), I could access my PC servers hosting all the samples I've used for years.  Rosetta mode is glitchy as hell for many, many things. 

Really appreciate the reply - I love my M1 mac and like others very eager for a compatible update (so I can tap back into my PC-hosted samples in particular)...hearing that it is at least a priority is a relief.  

Thanks for the suggestion.  I failed to mention that I also tried a 1024 buffer at one point with the same result.  I tried 512 and the max (32768) with no luck either.  

Does anyone know if you have to restart when you change the buffer for the revised buffer size to take effect?  It didn't make any difference in my end result, but curious to know for sure.  

I am trying to demo MIR and I have had a series of issues with it on my main workstation (Mac).  Right now I am getting NO sound when MIR is instantiated on the channel.  A few things to note about my setup:

1. Mac running 10.13.5
2. Logic Pro 10.4.3
3. VEP Server 6.0.17226 (Nov 2018 Update)
4. MIR (demo) activated on elicenser (I have run maintenance procedures on this)
5. MIR Roompack 1 demo activated on elicenser (Konzerthaus Grosser Saal is the venue I've loaded up)
6. Buffer settings - 256 in DAW, 256 for MIR
7. Only one channel of Kontakt 5 loaded and CPU load is low single digits so no processing power issues

I've had the already-reported issue around the GUI not being able to move icons, but the undocking and redocking of the MIR window solved this.  Right now, there is simply no audio when MIR is on a channel.  When I bypass MIR the audio is there.  When MIR is turned on there is no sound whatsoever. 

There is no Mute or Solo active in MIR on the dry channel and the volume is at unity.  The MIR main output settings the mic is the stereo MIR Default in the 7th row.  No sound on dry or wet solo (or blended).  

I'd really like to take advantage of voucher discount going on and buy MIR, but don't have confidence it will work yet and feel I'm running out of time!  Any help is much appreciated!
