Mac market share slips worldwide

Apple not infallible shocker

Although Apple may seem to be riding an unending wave of success after success, a new study shows that its worldwide market share is slipping.

"Mac usage share globally has been in a slow decline over the past several months," say the analysts at NetMarketShare, "dropping below 5 per cent in October."

Worldwide operating-system market share

Worldwide, Mac OS X market share is slipping

Those are worldwide figures — in the US, the story is different: "However, in the US Mac share is increasing," concludes the same report, "reaching 11.41 per cent in October from 11.32 per cent in September and 11.20 per cent in August."

US operating-system market share

In the US, however, Mac OS X market share continues to increase

Apple stock has closed at over $300 every day since October 13, it recently became the world's second largest company in market capitalization, and it reported revenues of over $20bn during its most recent fiscal quarter.

But if NetMarketShare's numbers are correct — their stats come from analysing web usage of around 160 million visitors per month — Cupertino's worldwide share is shrinking, not growing.

A few other NetMarketShare stats are of interest, as well:

Of course, all of these numbers are inexact, based as they are only on web usage. Still, they do provide a general sense of how operating systems are trending — and those trends imply that that Mac OS X is doing quite well in the US, but that Windows and mobile competitors are tightening their grip worldwide. ®
