Just to let all know, my Mac Mini M1 has been up and running for around a week now.....not a single issue yet running VW 2020! Very happy so far and the migration from my MacBook Pro 2012 was very straightforward and took around 3 hrs. I can now do final quality rendering which my MacBook pro never managed to do on VW 2014, so the graphics and processing is a good step forward.
For anyone considering this setup for the money very worthwhile. My whole setup cost £1750 inc vat (mac mini 16gb, 25" HD screen, logitec mouse and keyboard and HD webcam). The Mac 27" with i7 is £2300 so a good saving.
