Apple 27" Thunderbolt Display not working with new M1 based PowerBooks

I have a perfectly working Thunderbolt Display as it connects to my wifes older Macbook Air (2012), but absolutely will not turn on connecting to my M1 Macbook Air, using the Thunderbolt 3 to Thunderbolt 2 dongle.

The conclusion I have come to is that it is a software issue with Monterey. Some even go as far as saying, Apple is intentionally making them not work with the new OS so people will go out and buy the new 1600$ studio displays.

I have a MBA M1 and works fine with my TB display. Perhaps there is an issue with the octopus cable. You could get a TB2 cable and connect directly to one of the TB ports on the display and see if that works. Also unplug the display from the wall, wait 3 minutes and plug back in and see what happens. I have also used my Mac Mini M1 which also works with my TB display. I running OS 12.3.

I'm using 12.4.

Also just hooked the display up to a 2012 Macbook Air via straight thunderbolt connection and it worked flawlessly.

Its definitely a software issue. Both USB C ports on my M1 Macbook Air work too.

Not an issue with Monterey as I have mine using the TB display and no issues. I have Monterey 12.3.1.

A bad TB3 to TB2 adapter?

I've used 2... unless I've been extremely unlucky I don't think that's the issue.

Agree. The issue is with OSX 12.4. Apple needs to fix this ASAP. In the meantime, can anyone guide how to downgrade to osx 12.3?

Just updated my MBA M1 to 12.4. My TB display works fine using the octopus cable and adapter.

I have MBPro14 intel based, using Thunderbolt dock with USBC cable to connect to MB. It works fine with older Apple display and/or MB with BigSur, Catalina.
