I have upgraded to Big Sur 11.2.3 and EZ Superior drums version 3.2.4 and EZdrummer 2.2.0 are running in  Cubase 11.0.10.
Haven’t tried them in Logic Pro which I don’t use at present because it doesn’t support StevenSlate Drums in this configuration and SSD 5 is my favourite drum plugin (sorry Toontrack). Hope this helps but remain wary of MacOs updates.
Hi Woodstock 2, I have just checked my EZD SOLO, having never needed it I have never looked for it. But just now I looked at the Toontrack Product Manager to confirm installation – everything including the update for 64 bit SOLO is confirmed, the only thing is, it does not appear in the Browser of EZD when opened in my DAW so something is horribly wrong. I am working on PC with Windows 10 Pro together with Cubase 9.5.40 64Bit.
So your question unfortunately remains and must go to Toontrack direct. That is not the only problem with Toontrack and so I have gone over to Steven Slate Platinum as I have to work with reliable products, and SSD is unproblematic. Sorry Toontrack.
