Intel just announced the arrival of “atomic level” process technology

Since its beginning, rapid change has been a truism of the personal computer market. IBM ignited explosive growth with the announcement of the IBM Model 5150 back in 1981, and just a few years later started losing the lead in the market it created thanks to Compaq and other PC clone manufacturers. IBM wound up leaving the PC market, Compaq struggled and was acquired by Hewlett Packard which, after its own struggles, was torn asunder. And on and on and on and on. …


It’s all fun and games until someone makes the wrong purchasing decision

I check the tech press every morning looking for the latest Apple silicon rumors. Today’s nugget was an item in Mark Gurman’s Bloomberg Power On newsletter stating that the launch window for the new MacBook Pros is from September to November. Gurman explains, “these new MacBooks were supposed to launch earlier, but complications around the new miniLED display have held up production.” I’ve been holding out hope for a July launch, but that now seems extremely unlikely.

But while Gurman appears to be basing his reports on information leaked from inside Apple, its suppliers, and/or manufacturing partners, much of the…


Apple is going back to the future to create its best laptop yet

My writing focuses on Apple silicon, by far the most interesting change to Mac hardware since I bought my first Mac in 2008 (a Mid-2007 Mac mini). But the fact that I’m writing this on a Late-2012, 13-inch MacBook Pro is a testament to Apple’s hardware prowess not being limited to powerful, energy-efficient ARM processors.

I’ve been buying personal computers for almost thirty-five years. Ever since I purchased an AST Premium/286 Model 80 to launch my career-defining startup, Legend Software. For the bulk of that time, I bought a variety of IBM PC clones from AST, Toshiba, Compaq, Gateway, HP…


New Apple silicon MacBook Pros are expected to ship this year, but when?

I was thrilled back in October 2016 when Apple announced the first Touch Bar MacBook Pros. Not because of the touch bar, but because the new design was the “Thinnest and Lightest MacBook Pro Ever.” I had been using the Late 2012 13-inch MacBook Pro which weighed in at 3.57 pounds. For less than half a pound more I could upgrade to the 4.02 pounds 15-inch MacBook Pro with a quad-core Intel “Skylake” processor, a massive upgrade from the dual-core Intel “Ivy Bridge” processor in my 2012 MacBook Pro.

It took me less than a week to realize I valued…


Will it be enough to fend off rivals looking to claim Apple’s performance-per-watt crown?

Heavy lies the head that wears the crown. For years I repeated that Shakespearean quote whenever someone would unburden themselves of the tension from being in charge. I only just recently learned that “uneasy lies the head that wears a crown” is the actual quote from Shakespeares Henry IV, Part 2. Don’t I feel stupid. But however you phrase it, Apple currently wears the CPU performance-per-watt crown thanks to its M1 chip. And with Qualcomm, Nvidia, AMD, and Samsung aiming to take Apple down a peg, that crown must feel at least a little bit weighty.

Apple proves once again, it pays to make the whole widget

My AirPods Pro developed an annoying crackling sound last year, necessitating a trip to my local Apple store to take advantage of Apple’s free AirPods Pro Service Program for Sound Issues. The service appointment fell on November 17th, a date you might recognize as the first day of availability for the initial wave of M1 Macs. Quite naturally my conversation with the Apple Store Technical Specialist found its way to the new Macs and the fact that they were in stock. …


Making sense of the latest Apple silicon Mac-related rumors

When Mohamed M. Atalla and Dawon Kahn invented the MOSFET (metal–oxide–semiconductor field-effect transistor) in 1959, it was initially overlooked by their employer, Bell Labs. Despite its lukewarm reception, the MOSFET has become the most frequently manufactured device in history and is the beating heart of the digital revolution that transformed the global economy. Since Atalla and Kahn achieved a 20,000nm process size in 1960, MOSFET scaling and miniaturization have driven semiconductor technology forward.

From the 10,000nm MOS Technology 6502 used in the Apple II, to the 3,000nm Motorola 68000 used in the original Apple Macintosh, to the 600nm PowerPC 601


The hard is what makes it great.

It’s supposed to be hard. If it wasn’t hard, everyone would do it. The hard is what makes it great.¹

In the fall of 1987, I promised my newlywed bride that if I quit my job as a Member of Technical Staff (MTS) at AT&T, within six months we would have a small fortune courtesy of the network analysis software I would write after handing in my resignation. The catch, of course, was that my wife Joanne’s Systems Programmer salary would be our sole source of income until our software startup was a success.

At the time I was naively…


More CPU cores. More GPU cores. More memory. New designs.

Apple Silicon Has Been a Long Time Coming

These are exciting times for the Mac. Long overdue for a historic product line within shouting distance of its 40th anniversary. I was just starting out on my software engineering journey when the team of Mac pirates in Bandley 3 unveiled their treasure to the world in January 1984 with a 30-second Super Bowl commercial that has undeniably echoed through time more than the game that was played that day (the Raiders defeated the Washington Football Team, 38–9). …


The Epic v. Apple trial sheds light on the App Store’s origin

On October 17, 2007, Steve Jobs announced Apple’s intention to allow third-party apps on the iPhone. It was a decision that catapulted the iPhone into becoming the most successful product of all time. But Jobs’ announcement came 10 months after the iPhone launch at MacWorld 2007, which begs the question, when did he decide to pursue an App Store strategy? Was Jobs prescient enough to anticipate the need for the App Store or was he forced to acquiesce to insistent calls for an official SDK?

It’s an interesting question made more interesting by the conflicting answers provided by Stephen Silver’s…
