The new Macs come with 8GB of RAM and at least 256GB of storage. You can upgrade the RAM to 16GB for $200. The storage c

Of the two theories, I would place my bets on the second one. It just makes more sense for the MacBook Pro to be significantly more powerful than the MacBook Air. It should be better in every way. Not just in sustained performance. That way, it would better suit the “Pro” moniker. That way, it would justify the higher price tag.

Having said that, there is also the possibility that the inclusion of a fan is not for sustained performance. Instead, it is because the M1 chip in the MacBook Pro and Mac Mini are clocked higher than the one in the MacBook Air. Because the chips are clocked higher, they produce more heat. Hence, a fan is needed to cool these chips.

The signs that the mobility revolution is real this time are palpable. Automakers across the planet — in the U.S., Japan, China, South Korea, Europe — are launching suites of electrics, as are numerous startups. Front and center are Tesla’s fistful of successful vehicles, but GM, Audi, and Porsche are also wowing critics with their electrics. China’s Geely and BYD, too, are expanding fast.

The Mobilist name is deliberate, evoking a person who is out there meeting the folks involved in this gigantic transmogrification of our lives. So let’s go together to the front lines of what is happening, digesting, dissecting, and analyzing the latest developments, big and small. I welcome your comments, suggestions, corrections, and your own stories. Thanks for being part of the journey — and please share the blog with friends, family, and colleagues who you think will want to be part of it too.

Twice a week — on Tuesday and Friday mornings — we will meet and speak with the researchers and engineers who are attempting to take batteries the added distance and make electric cars cheaper, go further, and charge up faster.

Hardware-wise, these Macs are identical to the ones released in 2019 except for the replacement of the Intel CPUs with Apple’s M1 chip. Interestingly, Apple is using the same chip for all 3 Macs except for the 256GB version of the MacBook Air which has 7 GPU cores instead of 8.

“These were all things we were attached to and fond of, and they’re gone right now, so the loss is ambiguous. It’s not a death, but it’s a major, major loss,” says Boss. “What we used to have has been taken away from us.”

last week on how to automate some aspects of application startup performance. I’ve been looking into startup performance in general, and wanted to find a reasonable, automated way to derive startup duration for many consecutive runs. I published my approach for anyone that is similarly interested in startup performance testing.

To differentiate the MacBook Pro from the MacBook Air, Apple removed the cooling fan from the MacBook Air. As a result, the MacBook Pro should have better sustained performance. This means that the MacBook Pro will be more suitable for heavy workloads such as video editing and gaming. Without a cooling fan, I predict that the MacBook Air will throttle itself quite a bit but we won’t know by how much until we get our hands on the machine. There is however a silver lining for the MacBook Air. The absence of a cooling fan allows the MacBook Air to operate silently. This may not be important to you but I always found the humming sound made by cooling fans to be quite annoying. The hum degrades the computing experience especially when you don’t use headphones.

[Edited: Now that the Macs are available to the public it is clear that my bets were wrong. The fan is for sustained performance. This is true for both the MacBook Pro and the Mac Mini. The nice thing about Apple’s design, is that the fan doesn’t come on until it is needed to maintain peak performance of the M1 chip. Tests have shown that, the fan will kick in at around the 10-minute mark.]

I myself got drawn into the deceptively mystical world of batteries a decade ago, when the U.S. and the rest of the world — trying to extract themselves from the Great Recession — saw salvation in an electric revolution, and launched into a race to both help it happen and own it. I chronicled that technological and geopolitical race in a book called The Powerhouse, where for two-years I was embedded with a lithium-ion battery research team seeking to create the superbattery. But it’s now that the battle of battery and automobile titans is truly coming to a climax. Before joining Medium, I conceived and launched the Future newsletter at Axios. Before that, I was a foreign correspondent in the former Soviet Union, Afghanistan, and the Philippines, and the battery war is befitting of any of the geopolitical clashes I witnessed abroad.

Twice a week — on Tuesday and Friday mornings — we will meet and speak with the researchers and engineers who are attempting to take batteries the added distance and make electric cars cheaper, go further, and charge up faster. We will talk to the automaking teams who understand that, in terms of selling a lot of electric vehicles, the answer is affordability and style — consumers want cars that fit their wallet and make them proud. Like the smartphone now, cars have always been a statement about the motorist behind its wheel; EV makers need to think very hard about what status their product confers. The vehicles also have to be practical. Those who are getting it right are designing cool electric SUVs and pickup trucks with all the bells and whistles, and — for the economy markets of India, China, and elsewhere — compact sedans. (Pro tip: If an automaker’s signature new electric is a $100,000 ultra-luxury sedan, they are about a dozen years late.)

Appears to be because we can’t be sure what is coming, at what scale, at what price, and precisely when. These uncertainties are the new tension — and the subject of this blog. Reality is not as precarious as in Edison’s day — batteries and EVs for sure attract far more than their fair share of exaggerators and outright frauds — but there also are genuine, potentially transformational advances.

The largest remaining question at this stage is consumer demand. These automakers assume that mass numbers of people will embrace the new world they are imagining, but as of now, only niche slices of first-movers have done so. The coming three to five to eight years — the 2020s — will tell us whether combustion is truly in trouble.
