That is neat. But an undocumented tool is hardly a secret... [1] [1]: https://www.macobserver.com/tips/macos-monterey-includes-net...

You fool, it's a secret because you've now been admitted into the elect club of people who know something that the common herd are unaware of. You have now been elevated because you're special, you can see the world properly now. You are special . It's not a lazy, borderline-insulting clickbait headline at all.

You're insulted because the article title referred to this hidden tool as hidden?

Tangentially related: the wirelles chips that Apple uses make a world of a difference compared to my other machines (Lenovo ThinkPads in cheap to low-mid price range). They have signal where other devices don't, and, most importantly, Bluetooth does not interfere with 2.4GHz WiFi in a crowded apartment building in a crowded street. This makes a world of a difference. With my previous laptop, I simply couldn't use wir…

I'd say it's the antenna design not the actual chips?

Some of it is probably that Apple uses chips supporting three antennas instead of just two.

Now that Apple TV+ is a big player in streaming video, they need to make sure the incumbent internet providers in the USA are not playing traffic shaping games targeting their servers. It is just like how Netflix hosts a major speed tester.

Unfortunately most ARM‘s are also too weak

I benchmarked my cheap ($50) Walmart OpenWRT router that has a MediaTek MT7622 (dual-core ARM Cortex-A53 processor clocked at 1.35GHz); SQM is totally usable below 600Mbps or so.

Apple's WiFi and BlueTooth interference sucks tho. There are multiple reports of jagged moused cursor movement when using BT. Switching to wired fixes the problem. But it's weird that even Apple's MagicTrackPad doesn't work well with my MBP if I use it wirelessly :/

I use an MS keyboard + mouse with its own USB transceiver for wireless (Sculpt Ergonomic Desktop). So to be fair I haven't tried BT keyboards. AFAIK it's also 2.4GHz but not Bluetooth.

For me its mainly WiFi+BT Audio that I care about.

A surprisingly high number of my previous Lenovo devices had the problem that using both simultaneously would lead one of the two connections to drop. On Windows and Linux. The extent of the problem varied, the worst offender was a cheap Windows convertible, but my 2019 Ryzen 7 ThinkPad also exhibits this problem sometimes.

Very cool finding! Made me want to explore what other tools my mac has pre-installed in /usr/bin

One nice thing about macOS is that many of the system GUI tools are graphical wrappers around a command-line tool that does the real work. Most of them live in /usr/sbin I keep a list for my students. Here are some: diskutil mdfind mdutil plutil networksetup softwareupdate screencapture pmset hdiutil pkgutil caffeinate osascript defaults launchctl For example, mdfind lets you use Spotlight search on the command line.…

Nitpick: In general, the graphical tools don’t literally invoke the command-line tools. Rather, both the graphical tool and the command-line tool use the same C or Objective-C API (usually private and undocumented) provided by some system framework. But the command-line tools do tend to be more direct reflections of the underlying API, and more flexible.

I think he was in jest there, /s perhaps needed.

Something similar to the RPI 4 can already handle 1 Gbits SQM in pure software (CPU).

It's the OS coordinating them to not fight (desense tuning.)
