A couple of weeks ago, Apple released macOS Sonoma 14.4 with the usual list of bug fixes, security patches, and a couple of minor new features. Since then, users and companies have been complaining of a long list of incompatibilities, mostly concerning broken external accessories like USB hubs and printers but also extending to software like Java.

MacRumors has a good rundown of the list of issues, which has been steadily getting longer as people have run into more problems. It started with reports of malfunctioning USB hubs, sourced from users on Reddit , the Apple Support Communities forums , and elsewhere —USB hubs built into various displays stopped functioning for Mac users after the 14.4 update.

Other issues surfaced in the days after people started reporting problems with their USB hubs, including some instances of broken printer drivers, unexpected app crashes for some Java users, and problems launching apps that rely on the PACE anti-piracy software ( and iLok hardware dongles ) to authenticate.

For around three years now, the team of independent developers behind the Asahi Linux project has worked to support Linux on Apple Silicon Macs, despite Apple's total lack of involvement. Over the years, the project has gone from a "highly unstable experiment" to a "surprisingly functional and usable desktop operating system." Even Linus Torvalds has used it to run Linux on Apple's hardware.

The team has been steadily improving its open source, standards-conformant GPU driver for the M1 and M2 since releasing them in December 2022 , and today, the team crossed an important symbolic milestone: The Asahi driver's support for the OpenGL and OpenGL ES graphics have officially passed what Apple offers in macOS. The team's latest graphics driver fully conforms with OpenGL version 4.6 and OpenGL ES version 3.2, the most recent version of either API. Apple's support in macOS tops out at OpenGL 4.1, announced in July 2010.

Developer Alyssa Rosenzweig wrote a detailed blog post that announced the new driver, which had to pass "over 100,000 tests" to be deemed officially conformant. The team achieved this milestone despite the fact that Apple's GPUs don't support some features that would have made implementing these APIs more straightforward.

The MacBook Air is Apple's most popular laptop, and when the Apple M1 and M2 chips landed, they came to the Air first. That changed with the M3 chip generation , which came to the MacBook Pro and iMac first but left the Air untouched.

That situation should change early next year, according to a report from Bloomberg's Mark Gurman . Apple is reportedly preparing to launch updates to the MacBook Air, as well as several new iPad models, in "the March time frame." Apple hasn't released any new iPads in 2023, and the 13-inch M2 MacBook Air was introduced in July of 2022.

Gurman says not to expect design changes from the M3 Air. The M2 version introduced a new non-tapered design with a display notch, a new keyboard, and a MagSafe port, and the M3 Air should look externally identical.

When Apple announced the first three chips in its M3 processor family, the M3 Pro immediately stood out. Not because it was a huge leap over the prior generation, but because it was the first time we had seen Apple reduce key specs like transistor count, CPU and GPU core count, and memory bandwidth from one generation to the next.

Transistor count is an imperfect proxy for performance, but adding transistors is one of the primary ways to improve a chip's performance (ramping clock speeds up is another, which we'll revisit shortly). Both the M3 and M3 Max feature substantial transistor count boosts compared to their M2 counterparts—from 20 billion to 25 billion for the M3, and from 67 billion to 92 billion with the M3 Max. The M3 Pro has 37 billion, down from 40 billion in the M2 Pro.

That didn't tell us much by itself, but it did set us up to expect an M3 Pro that was a modest-at-best improvement over the M2 Pro. Now that we've been able to test one in a 14-inch MacBook Pro, we can confirm that this is the case. The M3 Pro is still decidedly faster than the regular M3, and building a chip with fewer transistors on a newer 3 nm manufacturing process has other benefits. But there's a wider performance gap between the M3 Pro and M3 Max than there was in the M2 generation, and you'll need to wait for the M4 generation before you see substantially faster Pro chips.

Apple’s new M3 Macs are starting to land on doorsteps today, and at least a few people are facing an odd problem: Their Macs are showing up with an old, outdated build of last year’s macOS 13.5 Ventura on them, and checking for updates isn’t giving them the opportunity to update to either the current version of Ventura (13.6) or the recently released macOS Sonoma (14.1).

Affected users have posted complaints on X , formerly Twitter, as well as places like the MacRumors forums . The unreleased build of Ventura appears to be build 22G80, where the officially released version from July of 2023 is build 22G74. So far the issue only seems to affect the basic M3 versions of the MacBook Pro and iMac and not the M3 Pro or M3 Max versions, suggesting that the M3 Macs were ready to go a few months before the more powerful versions.

So why did this happen, why can't these Macs update, and what can you do about it if you're affected?

Apple's 27-inch iMac was one of the few Intel Macs (along with the iMac Pro) to be discontinued with no direct Apple Silicon replacement . It used to be Apple's mainstream workstation Mac, but in the Apple Silicon era, that role has been filled by the Mac mini and Mac Studio , instead. The 24-inch iMac, recently updated with a new M3 chip , is a smaller machine focused more on casual day-to-day computing.

Some 27-inch iMac users have been holding out for a true large-screened iMac replacement. But Apple threw cold water on those hopes in a statement given to the Verge (and later reiterated to Ars), where it said definitively that it was not working on an Apple Silicon version of the 27-inch iMac. Users of 27-inch Intel Macs should either move to the 24-inch iMac or to the M2 Pro Mac mini or the Mac Studio if they need more performance, according to Apple.

Eternal optimists still holding out hope for a new large-screened iMac might note that Apple specifically mentioned the 27-inch iMac, which doesn't necessarily preclude the possibility of an even-larger iMac in the 30-something-inch range. But given Apple's usual aversion to discussing its future plans, an explicit denial does hit differently than a total lack of comment or a boilerplate "Apple doesn't comment on future plans."

The next year or two will be a turning point for people who bought into the last few generations of Intel Macs. AppleCare+ subscriptions are going to expire, batteries will begin to lose a noticeable amount of capacity, software updates and security fixes will gradually dry up , and normal wear-and-tear will slowly take its toll.

Every new generation of Apple Silicon Mac is another opportunity for Apple to get those people to update. Which may or may not help to explain why Apple is introducing its new M3, M3 Pro, and M3 Max MacBook Pros less than 11 months after releasing the M2 versions.

Like the early 2023 MacBook Pros, these late 2023 models are iterative improvements to the 2021 redesigns . They keep the things that made those laptops such a big improvement over the late-model Intel MacBook Pros while adding just a little more performance and one or two other minor improvements to entice people who still haven't made the Apple Silicon switch.

NEW YORK—None of the new Macs that Apple is announcing at its "Scary Fast" product event today look very different from the ones they're replacing on the outside, but the inside is another story. This is the first batch of Macs to include Apple's next-generation M3-series chips, and unlike past years, Apple is introducing multiple M3 performance tiers all at the same time.

The M3, M3 Pro, and M3 Max all share the same underlying CPU and GPU architectures, the same ones used in the iPhone 15 Pro's A17 Pro chip. Also like the A17 Pro, all M3 chips are manufactured using a new 3 nm process from Taiwan Semiconductor (TSMC). Let's dive into everything we know about the M3 family's capabilities, plus the differences between each performance tier.

Apple says that the performance cores in any given M3 processor can run up to 30 percent faster than the M1's performance cores, and that the efficiency cores are up to 50 percent faster. Most of Apple's direct performance comparisons were to the M1 generation, which is useful insofar as M2 Mac owners aren't likely to want to spring for M3, but it has the added marketing benefit of making the performance increases sound larger than they are.
