No matter which source you listen to, the latest quarterly data covering the PC market shows that Apple’s Mac shipments in the U.S. shrank in the third quarter of 2013, as Apple’s share of the PC market slipped.
The estimates released Wednesday by IDC and Gartner show very different pictures. In IDC’s research, domestic Mac sales were off 11.2 percent year over year in the third quarter, while the overall U.S. PC market slid 0.2 percent.
Gartner, meanwhile, found that Apple’s shipments slid just 2.3 percent, while the U.S. PC market was actually up 3.5 percent year over year in their models.
The numbers do not include Apple’s growing international sales numbers, nor do they include tablet shipments in the numbers.
Apple didn’t crack the top five PC vendors worldwide in either firm’s data. IDC and Gartner both had the top five, in order, as Lenovo, HP, Dell, Acer, and Asus.
