Apple on Tuesday unveiled three computers based on homegrown Apple Silicon processors, marking the start of a two-year transition that will replace Intel microprocessors with Cupertino-designed chips compatible with the Arm microarchitecture.

'In June, we announced that the Mac is taking another huge leap forward by transitioning to Apple Silicon,' said Apple CEO Tim Cook during a internet-streamed presentation. 'And we promised that the first Mac with Apple Silicon would arrive by the end of this year. Well, that day is here.'

Located in the open-source WebKit repository after being updated in February, references in the code found by 9to5Mac mention macOS '12.00' and iOS '15.0.' This is an unusual discovery, as. The core of Mac OS X is BSD Unix, and that OS has been around for two decades in open source form, inspected by all concerned. That's why Mac OS X is more secure than Windows, according to InfoWorld.

The processor shift demonstrates Apple's growing estrangement from Intel, which has supplied CPU parts for Apple computers since it displaced IBM during the PowerPC transition in 2006. And it represents an inconvenient repudiation for the chip giant at a time when Intel is losing ground to competitors like TSMC and AMD.

Now, with iOS 5 and PC Free, Apple takes a small step with the impact of a giant leap: It gives us a mobile device that requires no mothership. Steve Jobs likely imagined this future years ago. Pricing & Availability. The Mac products featuring M1 are available now to order from the Apple Store. The new mac products will be arriving next week to select Apple Store locations.

'The transition to Apple Silicon is going to have a profound impact on the Mac,' said John Ternus, Apple VP of hardware engineering.

Apple announced it is now taking orders for three devices based on its M1 Apple Silicon chip: the 13-inch MacBook Air ($999+), the Mac mini ($699+), and the 13-inch MacBook Pro ($1,299+), all of which are scheduled to ship next week. They run macOS version 11 aka Big Sur, which will be available for download on Thursday, and there are small discounts for education markets.

Intel fumbled ten, so Apple goes five

The M1, according to Cupertino, is fabricated by TSMC using its 5nm process technology. Compared to the previous generation of Intel-based Macs, the chip supposedly delivers up to 3.5 faster CPU performance, up to 6x faster GPU performance, and up to 15x faster machine learning processing, while extending battery life 2x longer.

Apple did not publish benchmark data to support its claims, though it insists it used 'select industry-standard graphics benchmarks' to find that its Apple Silicon Mac mini is up to 5x faster than the best-selling Windows desktop in its price range.

'Until now a Mac needed multiple chips to deliver all of its features,' explained Johny Srouji, SVP of hardware technologies. 'It had chips for the processor, I/O, security and memory. Now with M1, these technologies are combined into a single SoC [system-on-chip] delivering a whole new level of integration for more simplicity, efficiency and amazing performance.'

M1 also features Apple's unified memory architecture, Srouji said, which merges memory into a single pool so that all the SoC components can access the same data without copying between multiple memory pools over various buses. The result is a dramatic improvement of power efficiency, he said.

The M1 sports eight CPU cores, four of which are tuned for performance and four of which are tuned for efficiency, a la Arm's big.LITTLE arrangement, an eight-core GPU that can handle roughly 25,000 threads at once and offers 2.6 TFLOPS of throughput presumably at FP32, and a 16-core Neural Engine that delivers 15x faster machine learning than its predecessor, it is claimed.

It's expected to have up to 192KB of instruction cache and 128KB of data cache, per CPU core, which may explain how it's able to reach decent per-core performance. That would be also far beyond the cache sizes in rival x86 and Arm processors. The chip package includes the system RAM, too, as shown above.

The SoC also includes an image signal processor, a secure enclave, a storage controller with AES encryption hardware, media encoding and decoding engines, and an Apple-designed Thunderbolt controller for USB 4 (40Gbps).

Apple's M1-powered devices support macOS apps compiled as Universal Binaries (which bundle native code for both ARM64 and x86_64 chips) or as legacy x86_64-based code via its Rosetta 2 translation technology. What's more, they can run many iOS/iPadOS apps, which have been compiled for previous A-series Apple Silicon processors.

Apple SVP of software engineering Craig Federighi said the company has optimized all of its apps for M1, such as Pages, Numbers, Keynote, GarageBand, iMovie, LogicPro, and Final Cut Pro.

Adobe, he said, will make a universal version of Lightroom available next month and plans to do the same for other apps like Photoshop early next year.

Other important Mac apps will need further tuning before they ship with native Apple Silicon code. Microsoft said it aims to get an experimental ARM64 build of Visual Studio to developers next month and it has a beta version of Office for Mac that supports Apple Silicon waiting in the wings. The Homebrew package manager isn't yet working on Apple Silicon. Nor is Docker.

In June, Apple engineers mentioned a new virtualization layer was being developed to run Linux VMs and Docker on Apple Silicon. No mention was made during Apple's video presentation of how that project is going. VMware filled that void by declaring it is 'committed to delivering VMware virtual machines on Apple Silicon,' though it declined to say when.

Those demanding high-end Apple systems may wish to wait for next year's 16-inch MacBook Pro revision. None of the M1 models announced today can be bought with more than 16GB of RAM; current Intel-based MacBook Pro models support up to 32GB (13-inch) or 64GB (16-inch). ®

ARE you surfin' Safari?

It seems more and more web users are, with the internet research company NetApplications recording a steady rise in Safari's browser market share over the past year.

The Apple internet browser is a healthy third after Microsoft Internet Explorer and the open-source Firefox – not bad for a Mac-only application.

The latest figures from NetApplications show Safari has a 4.7 per cent share of web browsers, behind Firefox on 14 per cent and Internet Explorer, which has slipped to just under 80 per cent. Safari was up over 50 per cent on its 3.1 per cent market share of a year ago.

Safari's surge was accompanied by a similar increase in online market share for the Mac overall, which accounted for 6.2 per cent.

Web browser market share is a more reliable indicator of the Mac's install base than quarterly sales figures, as PC users are thought to replace their machines more often than Mac users due to virus and spyware issues. It also excludes the many Windows machines used as cash registers and dumb terminals.

Also, the Mac's share of the home user market is likely higher than browser statistics suggest, as many Mac owners use PCs at work, thus registering a 'vote' for Windows as well.

With web browsing becoming the main task of many computer users, browser choice is critical. Apple developed Safari, based on the Konqueror KHTML code base, when Microsoft axed Internet Explorer for Mac. With tabbed browsing and a smooth Mac-like interface, Safari has in a few short years gained a reputation as the best web browser on any platform.

It hasn't been a smooth ride, however. With Microsoft's Internet Explorer dominating the web until recently, Mac users have felt like second-class citizens, encountering websites that don't support non-Microsoft browsers.

However the situation has improved with Safari and Firefox gaining market share at the expense of IE. Now, with one in five internet users on a non-Microsoft browser, webmasters ignore them at their peril.

Safari's market share will grow even more when Apple releases the iPhone, which features a fully fledged version of the browser.

But despite its surge in popularity, Safari isn't without its critics. Some users have found it bogs down after a while, requiring a relaunch (or cache purge) to get it back to speed.

Some also have complained it lacks some features of other browsers, such as search bar plug-ins for sites other than Google, and PDF thumbnails of recently visited web pages. Safari add-ons like Saft and SafariStand have sprung up to cater to these requests.

And controversially, while Safari comes free with every new Mac, each major revision requires the user to upgrade the entire operating system. For instance, Safari 3, with its 'WebClip' feature for making a Dashboard widget from any web pages, will only be available with Mac OS X Leopard when it ships in the next few months.

However, for those willing to risk a less-than-stable browsing experience, the Safari team's 'nightly builds' are available as a free stand-alone install from nightly.webkit.org. For the technically inclined, the Surfin' Safari weblog (webkit.org/blog) is a good journal of the Safari progress.

Despite its relatively small user base, the Mac actually boasts the most number of web browsers of any platform, mainly due to the fierce dedication of its software developers. Some alternatives to Safari include:

Firefox: The second most popular browser in the world is also available for Mac, and offers features Safari doesn't, such as plug-ins for searching pretty much any major website from the search bar. However some users find it too Windows-like, as it has been ported straight from the PC version. Firefox for Mac is a free download from www.mozilla.com/firefox.

Camino: This is a more Mac-like browser based on the same source code as Firefox, and was previously known as Chimera. It offers many of the same features as Firefox, such as search plug-ins, but with a more tasteful Mac-like interface. More information and free download at www.caminobrowser.org.

Opera: This long-time rival to the big two of IE and Firefox keeps plugging away despite almost fading into obscurity. While most Opera action is in mobile phones and other devices nowadays, the desktop version remains in development, with the Mac version a free download at www.opera.com.

OmniWeb: One of the few Mac browsers that actually costs money, but its users will argue it's worth every cent. Features include PDF thumbnails of recent pages, HTML source editing, and the ability to restore a previous browsing session. OmniWeb costs $US14.95.

APPLE last week released the final update to Mac OS X Tiger, signalling that its next giant leap, Mac OS X Leopard, could be mere weeks away.

Mac OS X 10.4.9 offers a slew of performance, stability and security improvements, as well as greatly expanded mobile phone support in iSync. It is available in both Intel and PowerPC versions, and combo or point versions.

Apple also released a security update for Mac OS X Panther, and updated iPhoto to version 6.0.6 and iTunes to 7.1.1. All are downloadable via your Mac's Software Update control panel or from www.apple.com/support/downloads.
