Apple's new OS geared for multicore future
Apple began shipping Snow Leopard on Friday, but the true importance of the Mac OS X update likely will emerge well afterward. — That's because Mac OS X 10.6 begins a longer-term Apple attempt to get ahead by cracking a problem facing …
Context & Ripple Effects
Snow Leopard closes a loop opened more than a year earlier, when Apple first let out a few small details about what became the 10.6 release at WWDC 2008 — an update pitched less on consumer features than on groundwork. After reports in mid-August suggested the software might land ahead of schedule, Apple began shipping it on Friday, roughly two years after Leopard arrived to strong reviews in October 2007.
The significance flagged by CNET is architectural rather than cosmetic: Snow Leopard launches Apple's confirmed long-term effort to get ahead of the multicore computing challenge. The rollout has friction, though — a pre-launch warning that some applications may crash under the new OS set expectations that third-party software needs work before the platform's benefits fully arrive.
First-order effects
- Mac users who upgrade get an OS whose immediate value is stability and groundwork, while the multicore payoff depends on developers reworking their applications — the same compatibility gap behind the warning that some apps may crash under 10.6.
Second-order effects
- Developers face a forced choice between investing in parallel-friendly rewrites of their Mac software or watching their products underperform on Apple's flagship platform, while Microsoft and PC makers are pressed to show comparable multicore system software rather than competing on feature checklists.
Third-order effects
- If the pattern holds, operating systems become the decisive layer in who actually benefits from multicore hardware — shifting competitive advantage toward whoever ships the runtime infrastructure first, and making OS-level architecture, not application features, the battleground of the next upgrade cycle.
The trend: Operating systems are becoming the strategic layer for unlocking multicore processors, with Apple's Snow Leopard positioning itself ahead of the industry's parallel-computing curve.
