I bought a bunch of 45W+ USB-C chargers and put one in every room of the house. They're only about $20 each on Amazon. All of the family computers and phones can be charged on any of them. It's nice not to think about it.

You're putting a lot of faith in a $20 thing from Amazon, especially for something as crucial as the charger. Which brand have you put your faith in for these adapters?

I think your concern is overblown. They're all different brands, bought at different times, with the oldest an "Innergie" brand bought in 2016 and the newest a "Nekteck". Over those years, they've charged 5 different laptops and 4 different phones. No problems with any of the cables or devices.

Yeah this comment became outdated with the M1. Nothing from VMs to cross-compiling large toolchains has caused throttling in a fanless laptop. And that's while driving a 6k monitor and charging at full wattage.

The fanless M1 MBA throttles very easily, but only slightly. The M1 MBP with its fan that barely ever is audible pretty much never throttles.

Do any of them whine when under load?

PSA, if you're doing investigations like this: there's two important parts to "proving" your hypothesis. One is you look at the experimental results and then ensure that matches your hypothesis, which is what this answer does here. The second is that you remove confounding variables and actually figure out what the real cause is. For an analysis like this, I find it quite disappointing that nobody actually went back…

Does apple publish their source code so this could actually be done?

I tried this and it doesn't work. Turns out my MacBook was throttling to 30% due to overheating. This happens more frequently if you drive the GPU with an external monitor.

Unfortunately this is a very common problem with basically all modern high-end laptops that have a macbook-like form factor (e.g. not bulky gaming laptops with lots of cooling & ventilation).

Or you can stick it on a "laptop cooling pad", a plastic platform with fans in it that blow on the bottom of the laptop. Twenty bucks on amazon. https://www.amazon.com/ThreeLeaf-10-15-6-Office-Laptop-Cooli...

More than you would probably expect. https://opensource.apple.com/release/macos-115.html

I also recently discovered that something like 12% of CPU on my 2020 macbook air is used whenever I'm in a room with anything greater than perfect silence, by 'coreaudiod', because it apparently is constantly listening to the microphone built in near the keyboard and spending cpu cycles trying to filter out background noise.

> … 'coreaudiod', because it apparently is constantly listening to the microphone built in near the keyboard and spending cpu cycles trying to filter out background noise. Apparently running the signal desktop app in the background is enough to keep coreaudiod constantly wasting battery. Because signal is open and has been granted permissions for microphone and speakers, even if no call session is open?

There’s an app called Micro Snitch [1] that will alert the user when any application activates the microphone or the webcam and tell the user which application is doing it (including Apple’s apps like FaceTime). You could try it to confirm that it is indeed Signal that’s activating the microphone at all times and file a bug report with Signal. Listening in the background is a very serious issue because we don’t expect Signal to do that.

Edit: FWIW, I just remembered that I have Signal and Micro Snitch on an old MBP (running the latest macOS). I have never seen alerts for microphone activation when Signal is running (I don’t use it for calls from the computer). Nevertheless, if the coreaudiod issue is with an app using the mic, Micro Snitch may help.

Is this the 'high quality' Apple fan boys like to talk about?

No, I think they're referring to the pre-installed ads on the start menu. Oh wait, that's Microsoft. Or maybe it is the utter failure of a control panel (Bluetooth, ACPI, Audio) that is still a crash-fest with Focal Fossa. Let's face it, everything with a GUI now sucks. Hard.

Yeah maybe it will finally be the year of the linux desktop...

>> a machine that combines high end power hungry hardware, adequate cooling for that hardware, and a compact form factor.

There is. You don't need to keep that hardware running 24/7. That is a problem in the OS and associated software. Apple could disable all these monitoring daemons and accept the tiny delays in starting various things, accept some fan noise, accept a mic that isn't tuned to a room, accept that the computer will take a few extra seconds to wake from sleep, accept that charging won't be lightning fast. But that isn't Apple. That isn't what Apple's customers want. Those seconds are precious. They want everything all services to remain at attention 24/7 ready to attend their slightest need. If that means burning a few extra watts then so be it.

I am not an apple customer. My laptop is currently turned off... properly off. I can live with waiting a few seconds for it to boot because my time is cheap. So is my power bill. And so is my laptop's carbon footprint.
