Mac has been owned by several companies over the past few decades. Most of those companies have pretty much left them alone to run their business much as they always have run it. So the company we see today is pretty much intact in spite of having gone through several owners.
I've no idea if Bose is smart enough to leave them alone. When buying other businesses many companies go in and muck around and change too much. I've not seen anything at all regarding the Bose track record in this regard.
Still remember going into stereo stores back when I was a teenager and drooling over the Mac gear. I sure didn't have the money for it back then but always figured "some day".
