This is pretty nice, but why do a lot of Mac apps insist on living in the menu bar?

Making 1 click to access is faster than typing the app name in finder. Dock is usually full and used for different type of apps. Makes also constantly visible output possible with standard ui patterns.

OK, thanks. We understand what a menu bar is.

How is this conducive to the typical usage pattern of an app like this?

I would like to ask an LLM to rewrite it as Python CLI script. Is it even possible, or some Swift-only functionality is necessary?

P.S. Some time ago I learnt through HN of a one-line command in macOS which revealed the power (Wattage) of the connected charger. Can't find it now, but it was very useful.

Doesn't work for me. Says "No USB-C ports detected", although I'm pretty sure my monitor is connected via USB-C, and the monitor also has a built-in USB hub where my USB keyboard is connected to.

There's an issue on Github for this now: https://github.com/darrylmorley/whatcable/issues/2

I remember seeing a recent analysis where the vast majority of cables from Amazon misreported their capabilities. Is this tool going to be able to catch those, or blindly report what the chip advertises?

I think for real cables the delta could also be explained by damage or just a bad plug-in attempt, so even if you're not trying to detect counterfeit cables it could be useful to know:

1. What does the host support

2. What does the cable support

3. What does the device support

4. What actually got negotiated

can something like this be done for linux? maybe a wrapper for lsusb. I just found https://github.com/doug-gilbert/lsucpd which adds PD and more.

I am definitely gonna contribute or fork to create an open leaderboard of cable brands and quality :D

It won't tell you the _quality_

It just tell you want the e-marker said.

Could it be just a console utility?

Yeah I like the sound of the functionality but I don't like the idea of it taking up menu bar space. Console utility would be good or even a gui that can be quickly launched through spotlight

WhatCable says "No USB-C Ports Detected".

System info clearly shows my iPhone attached to USB 3.1 Bus.

...And claude fixed it already https://github.com/darrylmorley/whatcable/commit/7a3ad1363ae...

How do you define "thick" or "short" to a non-engineer/tech person? Relative to what exactly?

Thunderbolt 4 passive (over usb) is 0.8m in length, longer cables are active, up to two meters I think, so they do exist.

Pretty cool. What I don't understand is why both my USB@1 and USB@2 show the same connected devices. I'd expect to only see the respective devices. USB@1 is my USB-hub monitor, the other one is connected to my phone. Both show keyboard, etc. plus my phone as connected devices.

Good stuff, but it's telling me that my USB-C Thunderbolt cable has been plugged in upside down but the connector handled this. I was not aware that you can plug in something into USB-C upside down!

I wasn't either (insomuch as I had never thought about it), but it makes sense if you think about it for a second. If you have one end plugged in one way, and the other end plugged in the other way, each individual wire is flipped from where it should be. The fact that you _can_ plug it in either way means that the device on one end needs to be capable of recognizing that and logically reversing it. Same as automatic crossover in Ethernet.

That's all the program is telling you. It doesn't matter that it's backwards, but technically it is.

It's not always the case that the cable will correctly fix it. I think (hope?) any that any which didn't would be out of spec, but they exist...

Any plans to support installations through Homebrew?

Tangential, but LLT recently came out with their own lineup of USB-C cables guaranteed to be up to spec. And they have the main specs printed on each cable end, so you know what you grab.

That should be mandatory.

You mean LTT ?

We type two capital LLs a lot these days.

LoL

I like the idea and thanks for sharing, but I do think folks who vibe code or use Claude should take their time using, testing, and improving app before rushing to share. This was pushed/deved like 2 hours ago

And it's been updated, with full releases, many times since.

I like this tool, but I agree that it was rushed and it is still being rushed. I urge the developer to slow down and get it right.

Just because it got pushed 2h ago it doesn't mean they didn't test it on their end.

The 'plugged upside down' is weird for a USB-cable. Especially as that doesn't work. I tried plugging it 'the other way around' and it showed the same 'upside down' warning

Everyone knows you have to flip the USB cable twice before it’s no longer upside down.

Nice!
