Three million copies of Mac OS X Mountain Lion have been downloaded in the four days following its release on Wednesday, 25 July, Apple said today.
That makes the Hillside Cat the "most successful OS X release in Apple's history", the Cupertino crew chirped.
Don't forget that downloads doesn't equal buyers. A fair few folk, this reporter included, have downloaded it onto more than one machine.
Still, plenty of Mac fans will have coughed up $20 or 14 quid for the OS upgrade, though quite a number of them, we suspect, will be Lion users keen to get an operating system that treats them less like an idiot than their previous purchase did.
Not partaken? Mountain Lion - read our initial thoughts here - is now available through the Mac App Store. ®
