Does your charger have three prongs or two? Try grounding the laptop properly with three prongs.

M1 MBP's only come with two prong chargers, except in markets that use the British plug. Depending on the cause of the issue grounding could help, but you'd have to buy an extension cord with a ground.

There had been a grounded tail for apple powerbticks back to the era of g4 laptops.

It's still sold, just not included by default anymore (which is fine with me, since I have tons of them)

The common form of this bug is way older than 10 years and isn't really specific to macOS.

The problem is that audio devices do not have an explicit concept of "balance". It's set by adjusting the level of each channel. That volume adjusting process is not reliable. It often happens over an unreliable interface where some volume adjustments are just dropped. This hits a second problem: the audio device often has the ability to adjust its levels out of band with the host audio stack. Thus your laptop has to periodically poll the device to find out what the current actual audio levels are. When your laptop sees that the volume per channel is not equal, it doesn't know if this was caused by the device itself adjusting the balance or the volume adjustment message being ignored.

So for example:

1. User tells laptop to increase volume from 50% to 60%

2. Laptop tells device's right channel to go to 60% (success)

3. Laptop tells device's left channel to go to 60% (failure)

4. Laptop checks with audio device, sees 60% on right and 50% on left

5. Laptop changes audio balance to be nudged to the right

There are some ways to mitigate the problem. The audio stack could try to detect when its level commands are being dropped, but that risks the audio stack and device "fighting" over the correct volume. Better closer-to-realtime scheduling can reduce the risk of messages being dropped.

I don't think I've ever seen this or heard anyone talk about it. I've had at least one Mac since 2006 and all the engineering departments I've worked in since 2014 have been all Mac. Mostly at work I'm not doing much with audio, but at home I have had external DACs and equipment, I have a Scarlet interface, etc.. that I hook mics or guitars too from time to time, etc.. There are plenty of things I can complain about…

While people can have different experiences. I did have a L/R drift issue on an older Mac (PPC days) - Do you know what I did to have it resolved? I didn't write a twitter post, I contacted apple support. When the support person couldn't address it they assigned an engineer who worked with me to identify the issue - the bug was patched in the next x.x.1 That's literally all it takes. I've gone down this route 3 times…

Err... Wasn't the entire point of the post that the bug is nearly 10 years old?

I wish .DS_Store files were automatically gitignored... (though why should git fix such a stupid problem it didn't create...)

Pretty easy with a global gitignore

it's not my computer that produces these files... but yes, perhaps MacOS should ship with .DS_Store in a global gitignore by default (though I don't even know if it ships with git at all...)

It’s because despite those issues, depressingly macOS still delivers an experience that to most Mac users is preferable over that of Linux or especially Windows. Increasingly it’s not that macOS is incredible, but that the alternatives are that much worse. And I say this as someone who uses Windows and Linux daily alongside macOS. Windows isn’t going to get any better so long as Microsoft’s betting on pushing service…

Apart from MS's obsessive Bing pushing, I'd say Windows is easily better than macOS. Explorer beats Finder, PWA/Chrome profile support is nicer, window manager is better, archives are handled natively, touchpad gestures for eg. virtual desktops on small laptops are competitive. With a normal mouse, middle click for eg. hold to drag just isn't supported. The natural scroll settings for mouse and trackpad are bound, wh…

A lot of that is subjective. For me for example, Explorer vs. Finder is mostly a wash with Finder edging out Explorer in a few ways (e.g. toggling hidden file visibility with the key shortcut ⌘⇧. instead of having to dive into settings), and Windows window management is grating to the point that I have to keep a hard low limit on the number of programs open to get anything done under it. Archives are handled natively on macOS too, and I install 7zip on Windows anyway because its multithreaded compression/decompression is way faster than stock. Cloud storage is moot because I barely use it.

I'm aware, I have two M1s, but I had a static issue on my wired headphones at one point, and I fixed it with proper grounding.

Though I can't remember if it was my old Intel Mac, or one if the newer M1s. I haven't used the wired headphones lately.

I'll see if I can find them and report back here.

the only reason i've been using their shit is because i rely on software that doesn't exist on linux for certain hobbies and it was still drastically superior to windows which i refuse to use for any reason in my personal time, but now that it's not even better anymore, i'd rather just abandon those hobbies.

I haven't used Windows as a main-box in years, but was seriously considering it for the next upgrade. What's the beef?

For me, when they "accidentally" released a build that showed ads in Windows Explorer it was the end. I absolutely refuse to pay for an operating system which shows me ads. They walked it back after people were outraged and claimed it was a test build not meant for the public, but I don't believe them. I think if they hadn't gotten the push back they did, we would have ads in all facets of Windows today.

I'm using about every Apple product you've listed and only encountered the first problem and even then only sporadically. I won't be saying 'you're using it wrong' but I presume different ways of use or app workload can make a big difference.

Sometimes you go help a person who complains about such things, and they have instaled 50 obscure off-brand apps, all kinds of browser extensions, kexts, background services, crapware, and so on, and the system is like a zoo.

And sometimes these bugs are just stochastic in general. We had an entire 200 person office of macbooks. I'm the only one who got a weird display issue where it would randomly just corrupt the display for a period of time, rebooting wasn't a fix, there was no predictability as sometimes it would corrupt for a few seconds, once it was corrupted all day and I couldn't work. It finally stopped happening when I got a new macbook.

That same macbook also had serious audio "crackle" issues where doing anything that seemingly caused more context switching in the cpu would introduce loud pops to the audio. Rebooting would fix the issue until it would eventually come back.

I had nothing special or interesting installed. These things would happen from using a modern IDE and firefox.

not unix-like, forced updates which often break shit, mandatory telemetry, terrible ux, bloat, bugs, separate and clashing visual styles hamfistedly crammed together, hostile pushing of edge and bing... but most of all, it's a microsoft product. microsoft have demonstrated their hostility towards their paying customers time and time again.

for me personally, the final straw was after i had to replace a broken motherboard, windows wouldn't activate. i contacted microsoft and they told me it was a new computer so i had to buy windows again. i ordered a mac that day and gave my pc to a friend. each to their own but personally i'm never letting that dogshit touch any of my personal computers ever again. if i ever want to build a gaming pc again, steamOS is plenty good enough now for my purposes.
