Mac OS X Snow Leopard Launched 15 Years Ago Today With '0 New Features'

Today marks the 15th anniversary of Apple releasing Mac OS X Snow Leopard, which became available to purchase for $29 on August 28, 2009.

After advertising Mac OS X Leopard as having "over 300 new features" in 2007, Apple previewed Snow Leopard at WWDC 2008. Notably, during that year's "State of the Union" session, Apple showed a presentation slide that said the update had "0 new features," as Apple opted to focus on under-the-hood performance and stability improvements.

"We've built on the success of Leopard and created an even better experience for our users from installation to shutdown," said Apple's former software engineering chief Bertrand Serlet. "Apple engineers have made hundreds of improvements so with Snow Leopard your system is going to feel faster, more responsive and even more reliable than before."

With Snow Leopard, Apple said it refined 90% of the foundational "projects" that were built into Mac OS X. Apple pitched the update as offering a more responsive Finder app, an improved Mail app that loads emails up to twice as fast as before, up to 80% faster Time Machine backups, and a 64-bit version of Safari that was up to 50% faster than the previous version. Snow Leopard also took up around half as much disk space as Leopard.
