Mac OS Snow Leopard: Great news for Windows 7, too

OS X 10.6 includes Boot Camp 3.0, a new collection of software drivers that make Windows run much better on Mac hardware.

Every time I see the “I’m a Mac/I’m a PC” ads on TV, I can’t help but wonder, “Why not both?” And it has never been a better time for that.
It’s been a three weeks since I first got my hands on Apple’s new Mac OS X 10.6 Snow Leopard. (If anything, this means lots of hard work benchmark testing the product while trying to keep my mouth shut about it till now, which was even harder.)
Overall, personally, I found that while the new Mac OS doesn’t warrant a “wow,” it’s still definitely worth the $29 upgrade price.Mac users can read more about Snow Leopard in my colleague Jason Parker’s full review. On the other hand, for Windows users, especially Windows 7, the release of Snow Leopard is straight-on great news.

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 the entire computer industry: squeezing useful work out of modern processors. Instead of stuffing Snow Leopard with immediately obvious new features, Apple is trying to adjust to the new reality in which processors can do many jobs simultaneously rather than one job fast.
“We’re trying to set a foundation for the future,” said Wiley Hodges, director of Mac OS X marketing.
Apple shed some light on its project, called Grand Central Dispatch at its Worldwide Developer Conference in June, but most real detail was shared only in with programmers sworn to secrecy. Now the company has begun talking more publicly about it and other deeper projects to take advantage of graphics chips and Intel’s 64-bit processors.
The moves align Apple better with changes in computing. For years, chipmakers such as Intel and Advanced Micro Devices had steadily increased the clock rate of their processors, and programmers got accustomed to a performance boost with each new generation. But earlier this decade, problems derailed the gigahertz train.
First, chips often ended up merely twiddling their thumbs more because slower memory couldn’t keep the chip fed with data. Worse, the chips required extraordinary amounts of power and produced corresponding amounts of hard-to-handle waste heat.

64-bit Snow Leopard defaults to 32-bit kernel
Apple’s Snow Leopard operating system, released Friday, by default loads with a 32-bit kernel, despite running 64-bit applications.
While Mac OS X version 10.6 ships with a number of 64-bit native applications, the kernel itself defaults to 32-bit, unless the user holds down the “6” and “4” keys during boot time, at which point the 64-bit kernel is loaded. Only Apple’s X-Serve products, using Snow Leopard Server, boot into a 64-bit kernel by default.
“For the most part, everything that they experience on the Mac, from the 64-bit point of view, the applications, the operating system, is all going to be 64-bit,” Stuart Harris, software product marketing manager at Apple Australia said.
Harris said that at this stage there were very few things, such as device drivers, that required 64-bit mode at the kernel level but the option is available.
“But we’re trying to make it as smooth as possible, so people don’t end up finding that ‘oh, that doesn’t work’ because it’s not available yet,” he said.

Snow Leopard could level security playing field
Friday’s release of the new version of the Mac OS, dubbed Snow Leopard, could include some security features that would make it secure, or at least push it closer to the level of security that Vista and Windows 7 have, experts said this week.
Contrary to popular Mac fanboy belief, Macintosh is not more secure from a software standpoint than modern Windows; it’s merely safer to use because malware writers prefer to target the platform with the biggest install base, according to Charlie Miller and Dino Dai Zovi, co-authors of The Mac Hacker’s Handbook, which came out this spring.
“Apple hasn’t implemented all the security features that Vista has,” Miller said. “They made some improvements in Leopard, but they are still behind.”
If there is any truth to rumors circulating about Snow Leopard, the operating system security playing field could become more level as of this weekend and Mac users will really have something to brag about.

Report: Antivirus feature for Snow Leopard?
The next version of Apple’s OS X, which is due out Friday, may bundle antivirus capabilities.
Mac security firm Intego said that the latest version of the operating system, Mac OS X Snow Leopard, could have an antimalware feature, according to reports, in a blog post Tuesday.
The company published a screenshot which it said was of the security feature detecting a Trojan in a download, made via Apple’s Safari Web browser.
Intego pointed out that the most recent Mac adverts compare Mac security favorably to PCs. However, security experts have historically been divided over the relative security of Microsoft and Apple code, while some point out that any comparison is further complicated by the differing market penetration of Macs and PCs.
