When I try to download mac version there is 404 by google?
Windows one downloads fine. I have the device for testing just for the weekend. But it seems there are so may problems with it. 
chances are it probably won’t work anyway if your macOS is up to date.
Since introducing ARM to mac there is not much happend. Did someone decided to do many apps and did not calculated how much resources are needed to sustain them?
I use linux a lot too, will it work there?
Why there is no web app?
Why it is not open source?
Sorry for so many questions but I really like the hardware, just software seems so immature in architecture It would be so nice to to understand.
And: " “Rose_Connect” cannot be opened because the developer cannot be verified."
Usually I would force it, but since it is thru some suspicious Google link, and not even signed. Then no.
Rose, please fix this in a reasonable time. You would gain a long term customer.
Dear Rose Users
RoseConnect PC will be updated and released in the near future.
I was informed that it would be released next week at the latest.
Thank you
