No. We're still on the last stable version (2.5.0.1)

Every version after that either doesn't start [1] or makes random containers miraculously stop working. The 2.x version has your CPU burning, but that seems to persist in 3.x [2].

I stopped trying after they pulled in the auto-upgrade feature. Our team has no time playing bug-hunt easter egg at random times.

I honestly don't comprehend how this software gained such a wide adoption on Macs. Docker on Linux works flawlessly meanwhile.

No, and it's very likely that Docker may never improve very much on MacOS. There was already no shortage of trouble on x86 MacOS, I doubt the switch to ARM (and ostensibly, Big Sur) will make things any easier.

They now have an Electron-based config UI. That's obviously a big improvement.
