any chance there is a writeup on this anywhere?

I don't think I have enough for a writeup; I was actually looking into how Dock manages spaces so I have a bunch of general information on the SkyLight/CoreGraphics API. In short Dock grabs trackpad events and creates "SLSTransactions" to animate the windows around, but if there's anything in particular you're curious about I can try to go look that up specifically.

> SLSTransactions

thank you, that's a great pointer in case I look into that some more. Found https://github.com/koekeishiya/yabai/issues/148 which might be a good entry point for me

This kind of software is completely foreign to me. Private APIs and all these tricks for macOS integration. Very interesting

Yeah, window managers are generally the biggest consumers of that set of APIs (although even yabai only uses very few of the ones available). If you have more questions feel free to ask, although of course as these are all private APIs I may not have correct/any answer for you.

Yeah, I've set it up before but there's always a program or two that doesn't pick up the settings. And you still don't get the ctrl- line editing tools in text boxes like you do on Mac OS, so I feel it's more trouble than its worth.

Luckily I haven't run into that, but then I'm not using any commercial software currently and the stuff in the official repositories tends to work the way you would expect it to. Generally your settings should work pretty much independently of any program you happen to be running - xkb in particular is processing the key events at quite a low level. Regarding the line editing tools you mentioned that sounds to me lik…

Huh, last time I tried it, I think firefox had trouble picking up my settings. I think that was more than five years ago though, so it's likely things are better now. :)

Same, despite the overheating issue with my model, and the copious amount of OS issues with the more recent releases, I’ve yet to find a laptop that comes close to Apple’s track pad. To a point where sometimes I prefer the track pad over a mouse.

You’ve probably already heard about this, but there has been a large discussion about how charging from the traditional left side of 15” (and I believe 16”) MBPs results in heat and fan issues. A lot of people have had improved results just by switching power to the right.

Not for me on 16" 2019 Pro, the fans spin right up as soon as I start a Slack call and the base starts to melt rocks after about 15 mins.

Co-workers on the previous gen 15" pros also don't find this to actually be a solution. The issue is that Macbooks aren't a great investment for Apple, as the make more money in every other department, without anywhere near the upfront costs.
