Starting later in 2020, Apple is making a big change to its Mac lineup. Although Macs have used processors from Intel since 2006, future Macs will begin using Apple-designed chips like the ones in iPhones and iPads. Apple says that using its own chips will improve graphics performance and battery life for Mac laptops and will provide other less-tangible benefits relating to security and privacy. The first Mac using “Apple silicon” will be available by the end of the year (though we don’t know which Mac model that will be), and Apple expects its full lineup of Macs to complete the transition within the next two years.
Mac Intel Cpu
The Motorola 68020 was the first 32-bit Mac processor, first used on the Macintosh II.The 68020 had many improvements over the 68000, including an instruction cache, and was the first Mac processor to support a memory management unit, the Motorola 68851. The Macintosh LC configured the 68020 to use a 16-bit system bus with ASICs that limited RAM to 10 MB (as opposed to the 32-bit limit of 4 GB). While Mac hardware and software is denoted by its stability, the difference here has lessened. The odds of getting a virus or malware with a PC remain higher than with a Mac, but this is more about the numbers game than technology. About 7.5% of the computers in use are Mac, according to IDC, so hackers spend more time and creativity attacking PCs. The latest desktop Mac operating system from Apple i.e. MacOS Sierra 10.12.5 has already been released to the general public worldwide for Mac device users. But if you're using Windows-powered desktop PC or Laptop, then you can have an option to Install macOS Sierra Hackintosh on PCs and Laptops for Free.
This sets up a years-long transition period in which Apple supports both Intel Macs and Apple-silicon Macs with new features and software updates for a while but eventually drops Intel Mac support in favor of focusing on the newer, faster models with its own chips. So the question is: In the early phase of this transition, where we know Intel Macs will fade out but Apple-silicon Macs don’t exist yet, is it still a good idea to spend money on an Intel Mac right now?
The answer differs depending on the work you’re doing, but for most people we think it’s still pretty safe to buy an Intel Mac rather than waiting for one with Apple silicon. But we’ll keep this guidance up to date as the transition to Apple chips plays out and as the company makes more public comments about how much support Intel Macs will receive over the next few years.
What’s the problem?
Apple’s processors and Intel’s processors can’t just run the same software. Each uses a different “instruction set,” meaning (very simply) that software needs to talk to them in different ways to get them to perform the same tasks. Because of this, software developers will need to do extra work to optimize their applications to run well on both Intel and Apple processors. Eventually, as Intel Macs age and Apple-silicon Macs become more prevalent, those developers may stop working to make their apps run on Intel Macs at all.
If you’ve been using Macs since the turn of the millennium, you might remember something similar happening when Apple transitioned from PowerPC chips to Intel processors in the mid- to late 2000s. Apple and third-party app developers supported both PowerPC and Intel Macs for a couple of years, but the last PowerPC Macs didn’t get updates for nearly as long as the earlier PowerPC Macs, a development that shortened their useful lifespans. The concern is that history will repeat itself, and that the last few Intel Macs will be worse investments than both the Intel Macs that preceded them and the Apple-silicon Macs that will follow.
Most people should buy what they need right now
Our long-standing advice to people who need a new computer right this minute is to buy one. There’s always something new coming around the corner, but you never know how long you’ll need to wait for it or what features it will include. As of this writing, the 2020 MacBook Air and Pro lineups are as good as they’ve been in years, with much more comfortable keyboards than on previous models, more generous storage, and solid performance. Those computers aren’t suddenly bad now that Apple is changing processors, and they’ll be supported with new software updates “for years to come.” Apple won’t say exactly how many years that is (we have some guesses), but Macs typically receive new software updates for six or seven years after their release, and security patches for a couple of years after that.
That said, if you’re on the fence about buying a new Mac—maybe the one you have is working fine but getting old, or you bought a model with one of the old low-travel keyboards and want to upgrade to a better one—you should wait at least six months or a year to see how Apple handles the early phase of this transition. We don’t think the first Apple-silicon Macs will differ dramatically from current Intel Macs in how they look or work, but going forward you can expect Apple to introduce more and more features exclusively for Apple-silicon Macs.
When you should definitely buy an Intel Mac
If you’re looking to buy a Mac desktop instead of a Mac laptop, it’s better not to wait for Apple-silicon Macs. Apple confirmed that it still has some Intel Macs on the way, and the aging iMac is the most likely candidate for an Intel-reliant refresh right now. We also know that Apple’s current iPad and iPhone chips are a better fit for smaller, power-efficient laptops rather than high-performance desktops, which suggests that the iMac, iMac Pro, and Mac Pro will drop Intel processors closer to the end of that two-year transition period than to the beginning.
And if you run Windows on your Mac in any form—either by shutting down macOS and booting up Windows via Apple’s Boot Camp software or by running Windows on top of macOS using virtualization software like Parallels or VMware Fusion—you’re also safer buying an Intel Mac. Boot Camp won’t be available on Macs with Apple processors at all. Virtualization software may be updated to run Windows on Apple silicon eventually, but the Rosetta emulation software that Apple will use to run Intel apps on Apple chips explicitly does not support virtualization. At best, the makers of virtualization apps may be able to come up with their own workarounds, but Windows will likely run slower on Apple chips than it does on Intel chips.
When you should definitely wait for Apple silicon
One thing that Apple-silicon Macs will be able to do that Intel Macs can’t: download and run iOS and iPadOS apps and games directly from the App Store. Software for mac pro. Software developers can already get their iPad apps running as Mac apps that will work on Intel or Apple chips, but it requires extra effort that most developers haven’t put in.
Right now, it’s hard to think of an iOS or iPadOS app that would be worth delaying a Mac purchase—most productivity apps are already available on both, and the Mac-specific versions will still work better with a keyboard and mouse and be more consistent with the rest of your Mac apps. But it’s an intriguing option for phone or tablet games, and it’s likely to be just the first of a steadily growing list of things that Apple-silicon Macs will be able to do that Intel Macs can’t.
How long will Intel Macs get new updates?
Apple CEO Tim Cook has promised software updates for Intel Macs “for years to come,” but that’s a pretty vague statement to hang a multi-thousand-dollar purchase on. Apple is also notoriously secretive about its future plans. But what we can do is look at Apple’s last processor transition and its current support policies to come up with a good guess.
Apple announced the transition from PowerPC to Intel processors at its developer conference in June 2005. The company then released the first Intel Macs in 2006 and completed the hardware end of the transition by the end of that year, ahead of its original schedule. That meant you could still buy PowerPC Macs as late as 2006. Three years later, the Mac OS X 10.6 update dropped support for PowerPC Macs entirely, and those computers stopped getting new features or access to then-new apps like Google Chrome. PowerPC Macs did receive security updates until 2011, five years after they had last been sold, but no new features or other upgrades.
More recently, when Apple has dropped support for older Mac models in new versions of macOS, it has stuck to its timelines for “vintage and obsolete products.” For purposes of hardware and software support, Apple considers a product “vintage” if it’s between five and seven years old and “obsolete” if it’s more than seven years old. Macs on either of these lists are the most at risk for being dropped when new macOS versions are released; for example, when macOS Big Sur comes out this fall, Apple will drop support for all Macs released in 2012 and a handful from 2013.
Without confirmation from Apple, we can’t say how long Intel Macs will continue to be updated. But in a worst-case scenario, you ought to be able to get at least three years’ worth of active updates and security updates for a couple of years after that. At best, an Intel Mac bought in mid-2020 could see new macOS releases for six or seven years. Apple has also sold many, many more Intel Macs than it ever sold PowerPC Macs, so third-party software developers should be inclined to support Intel Macs for longer.
PC processors from Intel and AMD use an instruction set called “x86_64” or just “x86,” a reference to the original Intel 8086 processor used in some of the earliest modern PCs. Phone and tablet processors from companies like Apple, Qualcomm, and MediaTek use an instruction set called “ARM,” a reference to the company that invented it.Jump back.

The Best Wi-Fi Router
by Joel Santo Domingo
We’ve tested the latest Wi-Fi routers to find the best ones—from budget options to top of the line—to make your wireless network faster and more responsive.
Apple’s first-ever virtual Worldwide Developer Conference (WWDC) came with the usual slew of mostly predictable announcements, like upgrades to the iPhone and iPad operating systems, new features for its AirPod earbuds, and more. But its most striking news was a decision to shift from powering its Mac devices with Intel processors in favor of its own homemade chip, which it’s calling “Apple silicon.”
The Cupertino, Calif. tech giant claims the move will bring myriad benefits: it will make Macs faster, let them benefit from the company’s latest machine learning technology (for features like augmented reality, photo processing, facial recognition and more), and make it easier for developers to bring popular apps from the iPhone and the iPad to desktops and laptops. The transition to Apple silicon will take about two years; more Intel-powered Macs are yet to come.
Apple silicon differs from Intel’s processors by virtue of their architecture, which determines how a computer executes tasks. Apple is using ARM technology, which boasts faster performance with less power use compared to the architecture used by Intel (and its rival AMD). Generally, ARM processors make sense for devices like phones and tablets (because ARM chips use less battery power), while Intel and AMD’s chips have made more sense for high-performance desktops and laptops (where battery usage is less of a concern).
While the move may seem like a major blow to Intel—a longtime processor giant whose “Intel Inside” motto was once ubiquitous in computer stores—the company has already been moving away from making chips for companies like Apple, focusing instead on autonomous vehicle hardware, AI analytics, and high-margin, high-end processors for entertainment and gaming PCs.
“They recognize the challenges that are inherent in the client businesses these days and while they’re not going anywhere, they’re certainly trying to diversify themselves away from that,” says NPD Group analyst Stephen Baker. The Apple news, he says, is “not great, but in the long run I don’t think it’ll have an incredible impact on Intel.”
To be sure, Intel faces some headwinds. It still leads in market share, but it has consistently lost ground in the consumer market month after month to rival AMD (AMD’s share of the desktop market jump from 12% to 18% in the past two years, according to Mercury Research). Intel has also struggled to gain ground in the mobile world—it sold its ARM processor subsidiary in 2005, it killed off a pair of experimental augmented reality glasses in 2018, and last year stopped making 5G smartphone modems in favor of focusing on 5G infrastructure.
Perhaps Intel’s biggest struggle—and a reason it lost favor with Apple—is a never-ending battle with the laws of physics. Processors are composed of billions of transistors that perform calculations by turning on and off. The larger the transistor (measured in nanometers, or “nm”), the more power it uses. By using smaller transistors, you can fit more of them on a processor, which means more computing power, but also more energy efficiency. All told, the size of a processor’s transistors is a good indicator of how powerful that processor will be.
For most of modern computing history, chipmakers like Intel have been able to rely on “Moore’s law”—an observation that the number of transistors you can fit on a single chip doubles about every two years, thanks mostly to technological improvements. But, space being a finite thing, it’s getting harder and harder to cram transistors onto processors. As of today, Intel can make 10 nm processors, but even that achievement came after significant delays that put it behind the curve. By comparison, Taiwan Semiconductor Manufacturing Company, which makes mobile chips designed by Apple, has released smaller, more efficient 7 nm processors for mobile devices.
Intel’s delay in introducing 10 nm processors may have contributed to Apple’s decision to go their own way. “Having their own microprocessor architecture is something they’ve wanted to do since the Jobs era, for sure, to not be beholden to an outside partner,” says Jon Stokes, author of Inside the Machine: An Illustrated Introduction to Microprocessors and Computer Architecture, and co-founder of technology site Ars Technica. “I think the tipping point was when ARM started to catch up to Intel in … performance, and Intel stalled in processor leadership.”
Still, Intel is doing fine when it comes to powering other companies’ laptops, along with its other projects in AI and autonomous vehicle sensors. Its PC-centric business (providing processors for consumers’ desktops and laptops) grew by 14% year-over-year in the first quarter of 2020 as people bought new devices to work from home in the COVID-19 era. But in a sign of the company’s evolution, its best performing sector has been its data center group, which boosted revenue by 23% year-over-year thanks to an increase in cloud services.
What should the everyday Apple user make of the switch from Intel? It may end up being something to celebrate: Apple has a good track record of designing chips; the processor in the iPhone has outperformed Intel-powered laptops at certain tasks. Furthermore, the company is bringing popular third-party developers like Adobe on board early in the process, which should ensure that Apple silicon-powered Macs have plenty of useful software from jump (avoiding a critical misstep Microsoft made when releasing an ARM-powered Surface). That Macs armed with ARM will be instantly compatible with millions of existing iPhone and iPad apps is another nice bonus. And if Apple’s making Macs with iPhone-like internals, it’s not much of a stretch to imagine features like integrated LTE or 5G wireless connectivity, Face ID, and other mobile-only goodies come to its desktops and laptops. All told, Apple betting on itself might be the best decision the company has made since, well, betting on Intel.
