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.

Don't use third party chargers on A1706 or A1708 MacBook Pros. Doing so will kill a charge IC. It's well documented and I fix one or two of these logic board faults every month.

I searched but I can't find anything more about this. Do you have any links to share?

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.

It is really surprising how bad/slow Slack is compared to Discord

It's ironic. After all the time people spend accusing Facebook and others of opening your mic, it's Signal that's actually doing it

These things usually fix performance issues for me: - Open your macbook and clean out the dust. I do it yearly. It always helps. - Keep macOS and apps (e.g. browser) up-to-date. coreaudiod high cpu was fixed for me in 11.6. - Review login items, delete what you don't need. - Reboot, with the occasional nvram, pram reset - Review activity monitor, find apps that have background processes and delete the ones you don't…

Do you have the special screwdriver set?

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…

My MBP 16" can‘t run my LG Ultrafine 5K (sold by Apple) without fan noise.

Recently I also figured out that "automatic switching of graphic mode" (enabled by default) causes noticeable input lag. If I type text, the last typed character sometimes doesn’t show until another character is typed or I have to wait up to 5 seconds(!).

Turning off "automatic graphic mode switching" stopped the input lag completely, but the battery duration is down from like 10 hours to 3 or something.

A disappointing thing for a €3,300 device.

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…

> not bulky gaming laptops with lots of cooling & ventilation

Those also have cooling problems. I bought a bulky one with 3 fans just because it had a nice processor. It couldn't sustain high performance under load for more than 5 seconds even with the fans maxed out. Compiling some code pushes CPU temperatures into the 80-90 ℃ range. Scrolling a chat in WhatsApp Web also overheats my laptop.

I've given up on laptops. If they require cooling at all, the manufacturer did it wrong.

I needed some excessive CPU load to stress test a program's tolerance to scheduling contention, so I reloaded my chrome slack tab every 15 seconds. It worked surprisingly well...

It would work. However since the product is a laptop with the key word being lap... manufactures actually have to throttle beyond what would be required from a physical standpoint. While laptops can and do emit heat from the top & bottom of the chassis that is actually a negative since you have to prevent the user from causing discomfort/getting burned. Although this is a somewhat recent development/concern, you coul…

You don't have to. Look up erythema ab igne.

Thought only my cheapo Dell does this. DSP should’ve been offloaded to dedicated audio hardware. Doing it in software is just lazy.

I have a lot of nostalgia for PCI sound cards from the late 90's and early 2000's. That being said, I am happy that PC audio has been simplified to just minimally buffered DACs and ADCs, or a digital interconnect. Things actually just work without having to futz with ugly skinned proprietary software.
