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 the OS does nothing to notify you of overheating and throttling, which is an insanely stupid oversight by apple. I only found out because I noticed that the computer ran fine while running the AC, so I installed an app through Brew c…

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.
It wasn't that long ago that cheap USB-C cables were destroying laptops

Yeah this comment became outdated with the M1.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.

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. Apparently running the signal desktop app in the background is enough to keep coreaudiod cons…
> Imagine the cumulative kilowatt-hours wasted globally by all the CPU cycles spent by slack just to exist as basically a glorified IRC app. Conversely, imagine the global kWh saved by some micro-optimization to a key system call like malloc. Perhaps the biggest positive impact a single developer can have on our climate is to improve the efficiency of frequently used pieces of code. Even tiny optimizations would add…

Are you sure it's the Signal desktop app?
My initial hunch was while reading was that maybe it's your machine constantly listening for a "Hey Siri".
There are some reports of the same issue (and a possible solution) here: https://apple.stackexchange.com/questions/24913/why-is-the-c...
Though none of them mention Signal in particular.

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.

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). It's just not physically possible to make a machine that combines high end power hungry hardware, adequate cooling for that hardware, and a compact form factor. It's very sad that this is such a widespread problem and that there…
Or, potentially, buy an M1 MacBook since Apple’s ARM chips are much more power (and thus heat) efficient than Intel’s?
My 2019 16-inch MacBook Pro (2.3ghz i9/64gb ram) becomes unusable with 2 of the LG 5k monitors plugged in (one on each side). Worst MacBook I have ever owned.
There is a fix coming for the 5500m heat/wattage issues in the next OS thankfully. The MacOS drivers for RDNA are apparently just crap. This problem wasn’t present on the Vega GPUs, and it isn’t present while booted into Windows. To think this lasted all the way through Catalina and Big Sur is insane.
