As the final version of Mac OS X looms on the horizon, some Mac developers are saying - publicly and privately - that Apple Computer Inc. Should change, at. But despite its double life on x86 and ARM processors and its increasingly close ties to iOS and iPadOS, today's macOS is still very much a direct descendant of that original Mac OS X release.

It was two decades ago to the day—March 24, 2001—that Mac OS X first became available to users the world over. We're not always big on empty sentimentality here at Ars, but the milestone seemed worthy of a quick note.

SiteSucker is a Macintosh application that automatically downloads Web sites from the Internet. It does this by asynchronously copying the site's webpages, images, PDFs, style sheets, and other files to your local hard drive, duplicating the site's directory structure. SiteSucker can be used to make local copies of Web sites. Safari is a graphical web browser developed by Apple, based on the WebKit engine. First released on desktop in 2003 with Mac OS X Panther, a mobile version has been bundled with iOS devices since the iPhone's introduction in 2007. Safari is the default browser on Apple devices. A Windows version was available from 2007 to 2012.

Of course, Mac OS X (or macOS 10 as it was later known) didn't quite survive to its 20th birthday; last year's macOS Big Sur update brought the version number up to 11, ending the reign of X.

But despite its double life on x86 and ARM processors and its increasingly close ties to iOS and iPadOS, today's macOS is still very much a direct descendant of that original Mac OS X release. Mac OS X, in turn, evolved in part from Steve Jobs' NeXT operating system—which had recently been acquired by Apple—and its launch was the harbinger of the second Jobs era at Apple.

Cheetah, Mac OS X's initial release, was pretty buggy. But it introduced a number of things that are still present in the operating system today. Those included the dock, which—despite some refinements and added features—is still fundamentally the same now as it ever was, as well as the modern version of Finder. And while macOS has seen a number of UI and design tweaks that have changed over time, the footprints of Cheetah's much-hyped Aqua interface can still be found all over Big Sur.

OS X brought many new features and technologies we now take for granted, too. For example, it enabled Apple's laptops to wake up from sleep immediately, and it introduced dynamic memory management, among other things.

Mac OS X's greatest impact in retrospect may be in the role it had in inspiring and propping up iOS, which has far surpassed macOS as Apple's most widely used operating system. And indeed, macOS lives in a very different context today than it did in 2001. It was recently bumped from the No.2 operating system spot globally by Google's Chrome OS, ending a very long run for Mac OS as the world's second-most popular desktop operating system in terms of units shipped.

The most popular desktop operating system in 2021 is Windows, just as it was in 2001, but the most popular OS overall is Google's Android, which has dramatically larger market share in the mobile space than iOS does.

So while Mac OS X's influence is profound, it exists today primarily as a support for iOS, which is also itself not the most popular OS in its category. Despite Apple's resounding success in the second Steve Jobs era, as well as in the recent Tim Cook era, the Mac is still a relatively niche platform—beloved by some, but skipped by much of the mainstream.

After 20 years, a lot has changed, but a whole lot has stayed the same.

For almost as long as there have been Windows laptops, there has always been a giant squid in the room: Why is Windows’ battery life so damn pitiful? For years I thought it was simply a matter of display and processor technology outstripping battery tech, but when Apple entered the scene with the MacBook Pro and Air, and iPad, it became very clear that Windows itself was to blame. The battery life discrepancy between Windows and other operating systems has never been clearer than with the Surface Pro 2 and the 2013 MacBook Air — both have very similar specs (Haswell Core i5 CPU/GPU, battery size), and yet Apple’s laptop has almost twice the battery life of Microsoft’s tablet.

While it’s clear that Windows laptops with good battery life do exist, that’s really beyond the point — and usually just a result of large batteries powering relatively underpowered hardware. What we’ve noticed over years of handling a variety of Windows, Mac, iOS, and Android devices — and formalized in an excellent discussion by Jeff Atwood — is that Windows seems to magically decimate the battery life of laptops and tablets. You can have two devices with almost exactly the same specs (iPad vs. Surface RT, MacBook Air vs. an ultrabook), and somehow the Windows machine will have between 25 and 50% less battery life.

If you want to prove this yourself, try installing Windows 8 on 2013 MacBook Air. The 13-inch model (OS X 10.8) usually manages around 14 hours of battery life with light, WiFi web browsing usage — with Windows, that figure drops to around eight hours. The depressing thing is that the difference between Windows and OS X seems to be growing, too: The 2009 15-inch MacBook Pro managed around eight hours with OS X 10.5.7, and six hours with Windows Vista x64 SP1.

What’s causing Windows’ poor battery life? That’s a good question that no one seems to know the answer to. Atwood even asked Anand Shimpi of Anandtech fame, but he too drew a blank. The most sensible argument is that Apple designs its hardware and software to work synergistically — the software is perfectly tailored to make the most of the hardware, and thus it uses less energy to get things done. Microsoft, on the other hand, has to write software that works equally well across a massive range of hardware, and thus can’t include the low-level optimizations that would result in lower idle and load power usage for every CPU, GPU, and wireless chip/modem under the sun.

This argument falls down when you look at the Surface Pro 2 and 11-inch 2013 MacBook Air, though. Both devices were designed in-house, so Microsoft can’t claim that Windows isn’t optimized for the hardware. Both have Intel’s Core i5-4200 (Haswell) CPU, 4GB of RAM, and NAND flash storage. The MBA does have a lower-res display (1366×768 vs. 1920×1080 on the Surface Pro 2), but it also has a 10% smaller battery (38 watt-hours for the MBA, vs. 42 watt-hours for the Pro 2). The only other difference is that the MBA’s i5-4200U is clocked at 1.3GHz, vs. 1.6GHz for the Surface Pro 2 (but they both have the same Turbo Boost speed of 2.6GHz). Using Anandtech’s WiFi web browsing battery life benchmark, the Surface Pro 2 manages 6.68 hours — the 11-inch 2013 MacBook Air, on the other hand, clocks in at 11.1 hours. That’s Apple’s OS X delivering almost twice the battery life of Microsoft’s Windows 8, on almost exactly the same hardware. Go figure.

Even though the Surface Pro 2 was made in-house by Microsoft, it still has far less battery life than the 2013 MacBook Air, which has very similar specs.

Even though both devices were made in-house, the sad answer to this quandary — why Windows has worse battery life than OS X, iOS, or Android — is probably that Microsoft simply hasn’t put as much focus on idle and low-utilization power consumption as Apple and Google. Yes, the Surface Pro 2 is a first-party device where Microsoft controls both the hardware and software — but that doesn’t mean that Microsoft magically has the battery life expertise that Apple has been honing for almost a decade. We can’t say for certain, but given the huge disparity in battery life, there is either a massive flaw in the Windows kernel and low-level libraries resulting in massive power wastage (unlikely), or it’s simply a case of lots of little inefficiencies across the code base that add up (more likely).

Either way, though, the end result is that the awesome power consumption gains being made by Intel’s latest chips will amplify Windows’ lackluster battery life. As you can see in the chart above, the Surface Pro 2 has 40% better battery life than the original Pro, and that’s almost entirely thanks to the new Haswell chip. Going from 4.7 to 6.7 hours is nice, of course, but going from 10 to 14 hours looks, sounds, and is better. For fans of Windows, there’s no short-term solution here: Microsoft will need to do a lot of work to reduce its idle power consumption to OS X or iOS levels. If you’re looking for a good laptop for working from the coffee shop, the MacBook Air or tomorrow’s Haswell-powered MacBook Pros are likely to be your best bet for the foreseeable future.
