Is there i software to instal bos client on macbook?
There's no bOS apps for Mac. But you can open the client on Safari or on any other browser.
As for running the bOS on Mac, you can try sandboxed / emulator apps, like CrossOver or Winebottler, etc.
I don't know if any of these apps will actually work, but you can try it and give us feedback for any Mac users here.
