It seems like the M3 favors efficiency and thermals over raw power. This makes sense for the devices they've put it in. I wonder if we're going to see different processors (M3X or M4) for the next release of the pro desktops, that favor power over thermals and efficiency? Maybe there will be a kind of tick-tock, with odd numbered processors favoring efficiency and even numbered processors for power? M3, M5, M7 for th…

> I wonder if we're going to see different processors (M3X or M4) for the next release of the pro desktops I don't think they care much about pro desktops given the pretty embarrassing MacPro. They just don't mean much for the bottom line compared to consumer lifestyle devices. I expect they would be happily rid of the customer segment - annoying power users wanting low-level access and customisation. They keep their…

Apple just created a whole new Mac last year. It's a desktop. Last time they had created a new Mac was so long ago no one remembers.

For so long it was just Macbook Air, Macbook Pro, iMac, Mac Mini, Mac Pro. Now there's a whole new family member and it's a desktop. Apple is managing the slow death of desktops very well.

We're not talking about keeping up to date with the latest revision of python / java here, it's a shell that's woefully out of date. Apple is not RHEL backporting fixes so binaries continue to run for 10 years - in fact they seem quite cavalier about backwards compatibility.

Apple should declare Bash as deprecated, because they did everything to deprecate Bash, including replacing the default with Zsh, but classify it as such.

Hardly any AAA companies are optimising for the Apple GPU. MoltenVK is where all the interest is. Even if they did, there is very little in Apple Arcade which taxes the GPU, most target the lowest common denominator in terms of supported iOS/phone combinations. The original Apple Arcade strategy was for AAA titles, but for whatever reason that wasn’t pursued, so now we have a tonne of casual games and re-releases of…

> The original Apple Arcade strategy was for AAA titles Can you prove that statement? I bet you can't, cause it's simply not true. Every Arcade title is playable from an iPhone to a Mac by way of Apple TV. It was never going to get AAA titles.

I mean, they keep putting desktop class CPU+GPUs in their mobile devices - all just to play an Angry Birds remake?

I own almost every Apple device in the ecosystem, but I never game on them…

I’ve been using macOS in a multimonitor setup for years without much issue. A good bit of it boils down to macOS expecting monitors to be well-behaved, e.g. each having unique EDIDs (many don’t, instead sharing one across all units of a particular model) and initializing in a timely fashion. > Why can't I move a window to a monitor/workspace that has a maximized window? Because it’s fullscreened, not maximized. macOS…

Interesting - it's one of the killer features of macos for me. I use it to compartmentalize stuff I'm working on, and 4 finger swipe between them. I have a couple instances of VSCode, some app/debugging browser windows, some chrome profile windows etc... all running full screen and I spend my day brush swiping between them. It may be different for me because I work on a 14" macbook pro, mostly at coffee shops or unus…

You're one of the few. Most "pro"-users I know immediately go for 3rd party applications like Rectangle do have a better window-management setup. I never understood how Apple thinks this kind of window management is still OK. It's one of those stupid little Apple quirks like not adding calculator on iOS for so long.

This seems to be a lot of effort to rationalize the surprisingly small performance increase from M2 to M3. Initially the assumption was that M2 to M3 would be a bigger step than M1 to M2, not a smaller one. Perhaps TSMC 3nm is showing the limits of scaling?

It's a mixture of several problems: * TSMC N3B being a bit of a flop (yield issues, too expensive) * Brain drain from Apple's chip design teams over the last few years * Tim Cook trying to push the average selling price up to keep revenue growth going in the face of sales declines (e.g. hobbling memory bandwidth, reducing the number of performance cores for M3 Pro) I don't expect there to be a M1 style generational l…

For Apple, yes incremental increase but not for Huawei and recent Elite X.

It’s ridiculous that the base and Pro only support 1 and 2 external displays, respectively. Want 3 monitors? Have to pay for the Max. https://www.macrumors.com/2023/11/02/m3-chip-still-supports-...

Really you’re complaining you can’t plug in a 4th display into your computer? The fraction of the population who does can afford the Max, together with the 3 extra monitors. I’m not trying to justify Apple here, but this usage seems quite niche and it’s understandable to me to need a non-base setup. It doesn’t sound ridiculous at all. As a matter of fact, the vast majority of notebook users never even plug a single m…

I’m using the same Dell 1920x1200 monitors I’ve had for 10 years. And have been using them across many desktops and laptops. Including my current 2018 MBP that happily supports them (via 3 native USB-C ports, with one left over for a hub).

I say it’s ridiculous because the computers I’ve been using over the past 10 years — most of them much less expensive than a Max — have had no issues with them. Not because it’s a common need.

In a laptop?

I was thinking about the desktop variants. Apple Silicon is amazing. But if you’re doing heavy GPU it’s not very exciting.

It's very exciting in the local LLMs space, where the unified memory allows fast inference of large models.

I bought my M1 MacBook Pro not long after they were released. It's approaching 3 years old which is a pretty standard age for people to start looking at a replacement - I guess that's why they're comparing it to the M1. Slight tangent - even though the MBP has been struggling to handle my dev work (partly because the codebase I'm working on has grown significantly in the last two years) I won't be upgrading. Work bou…

> It's approaching 3 years old which is a pretty standard age for people to start looking at a replacement Is this really true? Three years sounds very new to me, and no one in their right minds would replace it.

i think a lot of personal users are seeing what corporate does and mirroring them. 3 years is pretty standard for companies to switch their leased/fleet laptops for optimum returns.

there's also the relatively static pricing of these and generally growing wages, making short upgrade times more common.

No. This is answered on the Homebrew installation page: https://docs.brew.sh/Installation

That page appears to very much describe that it does, in fact, still fuck your systems permissions… I’ll never install homebrew as long as the dev continues this amateur hour bullshit.

Could you explain what you mean by this? I don’t see it on the page, and I’m not sure exactly what you mean by “OS permissions”. See also here from 2016: https://apple.stackexchange.com/questions/253404/how-does-ho...
