You're comparing an OS that has one major release (windows 7) to one that has been essentially a rolling-ish release for ~10 years. (Mac)OSX (which you linked to) has been going/supported far longer than windows 7.
Yes but I'm also looking at the individual years. OS X has many releases and Windows has many releases; they're both effectively one product. Windows bugs are counted twice if they exist in different versions but are still effectively the same bug.
