While Apple pundits crowed about record first day sales of OS X "Lion," the rest of the world was worried that many of the new features were undesirable, broken or worse. Now comes word that adoption has topped out for now at only 16% of the Mac audience. No, nothing like Windows Vista.
The adoption rate of Mac OS X 10.7 Lion has seen a drastic slowdown after enjoying strong initial sales and is only running on 16% of Macs, giving it the third largest install base behind Snow Leopard and Leopard.
Mac OS X 10.7 Lion is being run on 16% of all Macs after seeing a highly successful launch, but sales have slowed to a crawl, barely outpacing adoption of Apple's previous version Mac OS X 10.6 Snow Leopard which is installed on 56% of Macs, according to a study by analytics firm Chitika.
