I have a Macbook Air, Apple silicon, I’m using chrome browser and have installed Trezor Bridge.
I connect my wallet to the computer, enter the pin number then go to metamask and click “connect to hardware wallet”
I select Trezor and then it gets stuck on a screen that says “Looking for your Trezor” until it eventually times out.
I have allowed popups in Chrome and restarted chrome and the computer and the wallett but I still get the same error. I tried it with Trezor Suite on and off. Four hours later and I still haven’t been able to connect the Trezor wallet to Metamask.
Thanks for your help. Paul.

Hello,
I have the exact same issue. Went through the troubleshoting, nothing helped.
Anybody managed to fix this issue? Thanks
This problem is huge. Everyone I know has same issue.
Metamask team - it would be simple to replicate on your end. Just plug in a trezor. See that you can connect to the trezor wallet within the same browsers. See that you cannot consistently get metamask and trezor to connect. This is up to date bridge, metamask and browsers.
So annoying. Just replicate it yourself.
