Actually the part about the same apps is true https://www.macrumors.com/how-to/install-any-ios-app-m1-mac/ The problematic part of that quote is where it claims that iPhones and iPads used to have Intel processors.

My iPhone7+ had an Intel baseband chip.

I don’t really agree. You can get cpus where eight cores share an l2 cache and you can pretty much obliviously program those and get totally reasonable scaling because the contention penalty is the L2 access latency. There are no 32-core parts with that property, so you’re paying for at best L3 access latency and maybe main memory, possibly even NUMA node-crossing latency.

Are there CPU architectures where 8 cores share a L2 cache? I'm not aware of any though I can think of several where 4 cores share a L2 cache, though those tend to be pretty lightweight cores. More often you see issues with the L3 cache being shared between 8 cores or no as with Zen 2 versus Zen 3. And since only lightweight cores tend to share L2s this isn't really an issue in terms of replacing heavyweight cores wi…

Sure, POWER9 offers pairs of SMT8 cores sharing L2 caches, that's 16 thread contexts presented to software that are all sharing an L2 cache domain. Intel "Tremont" Atom has a shared L2 cache for a module of up to 4 cores. Maybe that is the one you allude to as lightweight.

There's nothing to clean. Everything is pristine. The problem has even persisted across replacement cables and a full top case replacement (the keyboard, of course) where Apple scrubs the whole thing down before they give it back. Maybe I should superstitiously blow on it like it's an NES cartridge. It won't help, but maybe I'll feel like I have some agency.

Maybe bend the male usb out some.

Haha yikes. I'm not saying that your idea wouldn't work, but I'm definitely not going to do it. :)

Curious about this too. Anything more than 16 GPU cores seems like it'd too big to fit on die (share with CPU cores and everything else), so may need to be a discrete solution. Would Apple then make discrete GPU solutions using PCIe5? Makes sense for the Mac Pro given the edge cases for requiring multi-GPU solutions.

>Anything more than 16 GPU cores seems like it'd too big to fit on die 32 HP Core with 8 HE Core, 128 GPU Core give you ~650mm inclusive of L2 and SLC. Adding in I/O, NPU, ISP, VPU etc this chip should still be within the reticle limit of ~850mm2.

For some very loose comparison, the Fujitsu A64FX is a 60mm square package and has 48 ARM cores and 32Gb of memory, though no GPU cores.

I've had MacBooks since 2005, and I'm an amateur photographer. I really don't miss the ports or MagSafe at all. I actually like the USB charging better, as it allows you to connect the cord to either side, and it doesn't get accidentally knocked out if I use it on my lap. I've found that the cord being on other side is nearly as good as magsafe anyway, as it will be better positioned to pull out if it gets yanked. Ye…

XQD has never caught on and there hasn't been a camera released that uses them since 2018 Whats up with photo/video people gatekeeping “serious” vs functional Your point might have some merit but SD will hold out for the next 5-8 years that purchasers of this machine will expect

I mentioned what I use, not what everyone uses (Nikon D850, XQD card). True, XQD has mostly been replaced by CFExpress.

Regardless, the point remains that high-end cameras often use high-end memory cards that are not SD cards.

Apple’s goal is to have every portable computer work like an iPhone: you charge it overnight, then unplug it and use it unwired for a full day. This is why the charging port on the mouse is on the bottom, for instance. They never quite got their Intel laptops there, though. (Especially running MS Teams, Slack, and Chrome!) It’s kind of funny that, now that they can make a laptop that really does last all day on one c…

> They never quite got their Intel laptops there, though. Man is that an understatement. My work MBP - a 16" i9 - may as well be a desktop.

A desktop would probably be quieter than my 16”, which ramps up the fans at even a whiff of CPU usage.

Unfortunately that doesn't work for those of us that need to run compute intensive tasks, like browsing the web, or compiling stuff, or running docker. There's this stupid dream that the computer needs to be light and fanless and thin and sexy. It doesn't need to do that. I'm happy if it doesn't melt while trying to run some software I need to do my job.

> run compute intensive tasks, like browsing the web

lol, it's not only browsing though but web-infested Electron apps as well. Used draw.io (which is otherwise a fine diagramming app) the other day, with fans spinning up all the time. It's sad to see that draw.io was (and internally largely remains) originally a Java (Swing) app, seemingly only ported to a fscking browser frontend as a fashion statement when the exact same things it does I could do almost 20 years ago on a PowerBook using OmniGraffle.

Always a fun game of “which browser tab is burning my lap?”

USB-C would have been a great replacement... for DisplayPort/Thunderbolt ports. It's finally, years later, getting merely not infuriating to be stuck with only USB-C ports. Single port for display + charging is very nice, when it works. That iPhones and most iPads still don't use it is annoying. Having two kinds of charging cable around, years after Apple went all-in on USB-C for laptops, sucks. [EDIT] two kinds of c…

Apple uses lightning on their wireless keyboards and mice for chargring... I mean, what the fuck! They even came with lightning to USB-A cables, which won't plug into any USB-C Mac. Also it didn't come with a power brick presumably "to save the environment." I literally had no way to charge them. Totally asinine.

> and I never see USB-B to C cables ever Have you heard of these obscure websites called Amazon or eBay. They have tens of thousands of cables in every configuration you need.

The last time I searched amazon for usb-b to usb-c cables I genuinely couldn't find any. I bet I would have better luck searching for 'usb-c printer cable' as someone else pointed out, but I didn't think of that. Last time I needed a cable on short notice before a gig I had to settle for an adapter, and was really lucky that it worked. I've had other seemingly simple pin-to-pin adapters not work on me before. Next ti…

Just bought an USB-C to USB-B cable for my Macbook Air m1 and an iConnectivity midi interface and it didn't work. (Brand was Equip). Another cable from Delock to mini USB-A was fine though. Some of these cables seem to be only for charging so do some research. Best bet seems to be Apple adapter even tough I had them break every year or so.
