All devices with USB 3.0/2.0 interfaces trigger it on all my computers with new OSs. Keyboards, mice, weird things like hardware debuggers--they all fail whether the hub/dongle is Apple-approved or non-Apple. It will work for anywhere between a couple of minutes to about a half-hour and then stop working until I reboot the machine.

The two Macbooks I kept back on OS version work just fine. Two other 2015 vintage macbooks that were allowed to upgrade exhibit the bug. We cloned from the working 2015 machines to bring the failing ones back online--this is purely a software fault. All versions of USB-C based Macbooks exhibit the bug--even an M1-based Air.

This doesn't hit everybody. But it hits enough, and Apple has shown zero interest in fixing it. This is the company that produced a laptop that plugging into USB-C on the right gave signifcant performance differential from plugging into USB-C on the left, after all.

I'm done. I applaud Apple for the M1 hardware, but I'm leaving the abusive relationship. Laptop/desktop is second-class and will simply get worse with time.

That's Apple's prerogative, but it's time I stopped paying money to accerate my own demise.

Display Stream Compression, which worked perfectly on Catalina, has been broken for Intel Macs ever since Big Sur Beta 1 to this day. Completely and entirely non-functioning. I went from 4K HDR @ 144Hz to SDR @ 95Hz, HDR @ 60. Hundreds of reports, bugs filed, multiple monitors, multiple GPUs. Zero interest.
