(white) Fleetwood Mac album the best selling?

at that time, of course. And I mean just among the Warner Bros. albums

And not me, it's Mick (again) who says so:

We shipped 800,000 copies of Rumours to record dealers in February 1977. At the time, it was the largest advance order in the history of Warner Bros. Records. The cover depicted me and Stevie in our stage clothes, she in black chiffon and ballet shoes, me with my wooden balls hanging. In my left hand I hold the same crystal ball juggled by McVie on the cover of Fleetwood Mac.

Had that crystal brought us good luck? Fleetwood Mac had by then been on the charts for eighty weeks, sold four million copies, and become the company's all-time bestselling album. Within a month, helped by massive airplay on the new soft-rock FM radio formats that were springing up around America, Rumours began to climb the charts, and the press began to spotlight some of the traumas and travails we'd been undergoing.
