Bloomberg: Apple Plans to Move Macs to In-House CPUs as Early as 2020

Apple custom-designed processors coming to the Mac

Apple is planning to move its Mac computer line to its own processors as early as 2020, according to Bloomberg’s Mark Gurman. The report is attributed to unnamed sources who said the project is codenamed Kalamata, which is both a city in Greece and an olive variant.

The news sent shares of Intel lower more than 8% Monday. During the afternoon session, INTC was trading at $47.755, down $4.325 (-8.30%). Shares of AAPL were also trading lower at $165.31, down $2.47 (-1.47%). Both losses come during a broader selloff sparked by worries about the escalating trade war instigated by President Trump’s tariffs.

According to the report, Kalamata is part of Apple’s ongoing efforts to bring more of its product line in house. Apple has been making its own best-in-class CPUs for iPhone and iPad for years, and Mr. Gurman reported that Apple wants its Macs and iOS devices to work ever-better-together.

The report also said that the transition would involve multiple steps, and Mark Gurman tweeted it would start with Apple’s MacBook portable line.

Designed by Apple

The prospect of Apple moving Macs to its own processors was once a source of vague dread for me and lots of Mac fans I’ve spoken to over the years. Macs gained a lot of clout by moving to Intel in the early days of Mac OS X, and Intel has long made the most powerful CPUs for many applications.

So far, Apple has shown outstanding expertise in designing ARM processors, the kind of processors found in iPhones, iPads, and most mobile devices. ARM dominates mobile in the first place because it excels at using less power. The kinds of data crunching needed for desktop computing has remained firmly in the realm of Intel—and x86 processors by AMD.

The worry, therefore, is whether Macs would take a hit in terms of performance if Apple moved the Mac to its own ARM processors. That is a possibility, but the reality is that Apple has quietly become a powerhouse in designing best-in-class ARM processors. If Apple thinks it can move Macs to ARM, I’m excited to see what that might look like.

And, it’s possible Apple is also working on its own x86 processor, and if that’s the case, I’m even more excited. One of the key advantages in making its own processors is the ability to have those CPUs do what they need to do, when they need to do it. At the same time, Apple’s control of the software, too, means Apple can wring every bit of both power and efficiency out of those chips in ways no competitor can.

Accordingly, I greet this news with enthusiasm and can’t wait to see what Apple thinks it can do.

Remember that Apple hasn’t said anything about this, it is speculation.


If it is ARM that might still run versions of Linux and Windows. Wasn’t there a version of Windows for their ARM-based Surface tablet? But it had reduced capabilities and couldn’t run all x86 apps.


If the lose Linux and Windows native support they will lose users.


For me it doesn’t matter whose chips are inside, but I do need to dual boot and run Windows natively. Much more than I need iOS apps on the desktop.

If Boot Camp ever goes away, it’ll be a day of reckoning I don’t want.

Well at least then give us an OSX Home app


Windows on ARM has been public for a while. I saw this as Microsoft pre-empting Apple, not to mention a boon for Apple if it changes processors. I’m FAR less concerned which processor Mac OS runs on, than the dumbing down of Mac OS to gain feature parity with iPad. That’s just insulting to Mac customers, not to mention a clear step in the wrong direction for ‘proper’ computing, which some of us still do. Sure there are a lot more people who don’t need a computer to do social, email, word processing etc. iOS is perfect for them. And… Read more »


Seems to me it makes sense to convert non-pro laptops to in-house chips to start with and leave pro laptops on Intel until the switch can be made transparently, meaning Intel compatibility without loss of performance.
Too many users need to run Windows for business purposes for Apple to drive them away.


One problem, QA. People already complain about Quality Assurance from Apple, more chips equals more problems.


I can already see the G3/Intel processor speed tests running in a keynote presentation…

“I know runs at 300mhz, but in Photoshop it runs 3 times as fast as that Intel at 1ghz! See, look at the speed tests”
