Rumors about that new 15-inch MacBook Air and the future Mac Pro keep heating up, as Joe Rossignol reports:

Apple this week filed a new listing in the Bluetooth Launch Studio database, a move that sometimes foreshadows the launch of new products. The filing does not mention any specific products, but it lists the latest Bluetooth 5.3 standard and references a prior macOS-related listing, suggesting the filing could be related to upcoming Macs.

Apple is rumored to be planning new versions of the MacBook Air and the Mac Pro for release in the first half of 2023. The new MacBook Air is expected to feature a larger 15-inch display and the M2 chip, while the new Mac Pro is expected to have the same design as the 2019 model with a new M2 Ultra chip. Both new Macs could be announced as early as March or April, potentially alongside the release of macOS 13.3. However, there remains a possibility that the new Macs will not be announced until WWDC in June or later.

Bluetooth 5.3 is present in a bunch of new Apple hardware, including the new M2-based MacBook Pros and the M2 Mac mini. It is not present on the M2 MacBook Air introduced last year. That machine ships with Bluetooth 5.0.

Jason Snell, writing at Macworld:

So what makes a Mac Pro a Mac Pro? If it’s a tower enclosure, Apple’s got a relatively fresh one from 2019 that it can just roll out again. (Gurman says that’s now the plan, which is also a little disconcerting when you consider that the original reports suggested a new, half-height enclosure and that quad-M2 chip.) But what’s inside the Mac Pro matters, and if it’s just an M2 Ultra chip, it’s hard not to consider the new Mac Pro just a Mac Studio that moved out of its apartment and into a mini-mansion.

Does it help if there’s expandable internal storage? Sure, I suppose–it’s certainly a lot neater than attaching drives via external ports. Does it help if Apple offers additional M2 GPU cores via some sort of proprietary add-on card system? Maybe, if it’s done the extra engineering work. What about RAM expansion? Sure, but again, such a choice would undercut the work Apple has done to create a pool of fast, shared memory right next to the CPUs and GPUs.

And all that custom work, all those distortions to what makes Apple silicon so successful, would be done for a product that’s a niche of a niche–and it’s work that Apple’s chip design team could have spent on a next-generation chip for the iPhone, iPad, and Mac.

Howard Oakley:

There was a time when the great majority of apps consisted of just an app bundle, created their own settings file in ~/Library/Preferences, and that was that. For various reasons, this became steadily more complicated, with some apps assembling arrays of files and folders in /Library/Application Support, and in recent years many apps have required helpers too. One common reason for this is that they need to perform certain functions with elevated privileges, such as root. To do that, they have become even more elaborate, with Login Items, property lists installed in folders like /Library/LaunchAgents, and more. This article explains how Ventura is trying to make things simpler again.

We spoke about this recently on Mac Power Users. While the new system attempts to give users more control over what’s happening on their Macs, I can’t help but think the UI for it is too confusing for most users:
