Hey guys, I'm doing a research paper, and I need to find a graph of sales for Mac products from a reliable source. I don't know where to look, so any help would be greatly appreciated! I want sales from at least 2000 to present.

I did find this: http://www.systemshootouts.org/?q=node/197

Is that considered official?

I'd like a press release from Apple if anyone can find one. I've had absolutely no luck.

No idea about your graph, but Wikipedia has a slot for OS share with more links-

Thanks you two, I got it now. ^_^

IDG and NPD do marketshare numbers quarterly for Mac. I have access to a the last  decade or so if you need them, thanks to my work. Though I imagine they can be compiled from other sources as well. I think the numbers I can get are more US oriented though. PM me if if you want me to pass along anything specific. I'll double check tomorrow about what I can and can't share technically these reports are confidential, but I think the percentages are fair game, especially  if they are publicly released. Also...

Apple also releases raw sales numbers which I'm sure could be compared against public data to get a good idea, especially since they break it down in to Americas, EU/Others , JPN and Asia/Pacific. They also provide a laptop/desktop split. I will say that the latest NPD I read put Apple at 9.8% (abouts) marketshare U.S. with something like 25% laptops and 5% desktops share. Of course those obviously omit iPhone/iPod and iPad. IDG put them a bit lower at something like 8.8% US.Not sure if I read far enough to hear IDG's desktop/laptop breakdown.
