Trendforce:

Apple overtook ASUS and Acer to become the No. 4 brand in the annual ranking. New MacBook models and strong demand in the U.S. drove Apple’s notebook shipments, bringing its global market share to 10.34%.

Even the 10-percent marketshare number doesn’t tell the whole tale. Macs, on average, are priced more than double typical Windows PCs, which means the Mac has a much larger revenue-share and profit-share, with some research indicating that Apple owns more than half the entire industry’s profits.
