An alternative since Across doesn't work on Mac

Across stopped working on Mac since MacOS Monterey but keeps blaming Apple for destroying the bluethooth stack...

As a paying user of across I have some sympathy for this problem but I would also expect it to be solved after some time.

But sadly no. I have waited and waited but new version after version keeps blaming Apple and still doesn't work with Mac... while the competitors does work ... so how can that be?

If Apple destroyed the bluetooth stack would not all Bluetooth implementations have the same problem?

How come then that for example https://www.sharemouse.com/ works perfectly on Mac?

 

And still taking money and profit from false statement of support.
