User reports that Scratch Link did work as expected in macOS11 Big Sur, so this appears to relate to the upgrade.

Thanks for the report! I'm sorry to hear about the trouble. It seems a lot of applications are having problems with Bluetooth in macOS 12. We'll try to figure out the problem but I can't promise it'll be quick.
Here's an example of the kind of thing I see when looking for information about Bluetooth on macOS 12: https://developer.apple.com/forums/thread/694146

Could it be that recentDevices is not populated correctly? I got to my surprise connectivity to Lego devices after I started the old Scratch Device Manager, which has no sense except that perhaps it hit the good point in the BLE stack. I have been unable to reproduce :-(

It seems that only BLE session works fine on macOS 12.3 beta. BT session still have some problems, but I think it's getting better.

I'm having the exact same issue trying to use Scratch Link to connect to LEGO Boost, on macOS 12.2 on a MacBook Pro (14", Apple Silicon processor). I'll subscribe to this issue to see if anything comes up in terms of a fix — and I'm happy to provide any debug information that might be helpful.

Basically I compiled bricklife's fork and followed the suggestions discussed here:
bricklife@a521a48#commitcomment-64576240
```
var thisProcess = ProcessSerialNumber(highLongOfPSN: 0, lowLongOfPSN: UInt32(kCurrentProcess))
TransformProcessType(&thisProcess, ProcessApplicationTransformState(kProcessTransformToUIElementApplication))

With Scratch Link 1.4.3 and macOS 12.3, micro:bit has been successfully found and connected.

Guys,
Is it working for macOS 12.3.1, scratch link 1.4.3?
It is not working for me with the above :(
martinwork commentedon Jun 25, 2022
Just tested with M1 mac mini and macOS 12.4, Safari 15.5.
The website at scratch.mit.edu will not link via Scratch Link, but the Scratch app v3.29.1 appears to work fine.
bricklife commentedon Jun 27, 2022
Scratch Link 1.4.x now does not support Safari. Read this section: https://github.com/LLK/scratch-link#secure-websockets
martinwork commentedon Jun 27, 2022
Many thanks for pointing to that @bricklife
It's seems to be working for me in Chrome.
