Net Applications: 18% of Mac Users Have Upgraded to Snow Leopard
On August 28th, Apple released Snow Leopard, which is version 10.6 of the Mac operating system. Since then, it has had rapid adoption. On the day of Sept. 29th, the global share of Snow Leopard was .91%, and the overall Mac share was 4.93%. This means 18.45% of Mac users have upgraded to Snow Leopard in just one month after its release.
Readers will note weekly cycles in Apple's market share showing an increase in share on weekends, presumably due to the dominance of Windows-based PCs in business settings during the work week contrasting with primarily home computer use on weekends.
