I hope Apple currently has a team focused on macOS perf.

I worked on the team in charge of improving iOS (13) perf at Apple and IIRC there was no dedicated macOS “task force” like the one on iOS.

Luckily some iOS changes permeated into macOS thanks to some shared codebases.

It's not surprising. Macs are less than 10% of Apple's revenue.

It's surprising that they don't improve the developer experience for their own developers using their own tools, including hardware.

Apple uses the same tools you do. They just might not be using it like you are; you can find a lot of features that clearly have no reason to exist outside of Apple nonetheless shipping with their software.

No. A special directory can be created at the root of the file system called /AppleInternal. Then, if you work at Apple, you can put some special files there that do stuff. I've read somewhere that they are able to easily disable all of this privacy protection crap and other annoying stuff.

There's nothing really special about /AppleInternal, it's just a fairly normal directory that a couple of tools change in order to do things like offer more detailed diagnostics or the option to create a Radar. On a normal internal install there are some internal utilities, many of which are listed here: https://www.theiphonewiki.com/wiki/Category:Apple_Internal_A.... But their code is all Xcode projects and stuff, it's not like they're really using special tools for themselves except in certain cases. There are a couple of internal tools that possess entitlements to bypass security, but more often than not engineers just run with the security features disabled, which you can do yourself.
