Could it just be that christmas shopping skews these statistics? Then again, statistics for the previous years don't seem to support this theory.
All in all this doesn't seem like information I would want to base any claims on.
It's not too far-fetched to believe that the Mac's share used to be roughly 7-8% and is now roughly 6-7%, which is as much as I'd take from Netmarketshare numbers.
However, that would be against the historic trend of the Mac's increasing market share, and I don't see any evidence for it in the marketplace. The people who were waiting for new Macs didn't stop using their old Macs.
For this, I always try to compare stats from three sites, because they all differ.

[1] I suspect it is that macOS + iOS would be a better numerator to pit against "Windows on all devices". However the GP having corrected themselves immediately means its not clear what the point is.
