v1.5.0-beta.9 is up #634

Welcome back. While confirming that #580 has been resolved, I noticed that for an extended period, WhatCable reports that the charger is „Plugged In, Charging on hold“ despite the power monitor indicating that the MacBook is indeed charging. 
It takes between 10 to 40 seconds for the app to accurately display that it’s „Charging well“. Current percentage is 46%, so way below any automatic charging restrictions. It didn't take that long in previous versions. When starting the app in this beta version, I get a additional blanc window. 
It shows the title in my system language (German) while I have manually set the app language to English. I couldn’t find any issues related to the problems you wanted us to investigate, but I noticed that this version seems to be more laggy than the previous one. It’s not a traditional hang, but I experience micro stutters when I plug the device into my Lenovo dock and scroll up and down the device list. I was able to attach a instruments recording (Reporting threshold set at >100ms) and record the hangs for
For cross reference, I did the same with This version introduces the measurement of the charging resistance, which my Mac might not support. Might also because it's charging and there isn't much variation in the power draw. I will test it again when my Mac is fully charged and the power drawn from the brick will vary.

I also get this blank “WhatCable Settings” window after updating. It pops up every time I restart WhatCable. |

Thanks @official-Cromatin and @jimmyorz working on those now. |

@official-Cromatin @jimmyorz thanks both. Beta 10 is out and hopefully addresses the issues raised. |

hi
Should it be reporting different MagSafe cables?
Or did I miss something.
I have 3 cables, a genuine black and a genuine white, then a fake cable, they all identify the same

@aldobalducci your screenshots didn't come through, as replying by email drops images. Could you post them here in the discussion directly, one per cable, with "Show technical details" turned on? Then I can see exactly what each cable reports. For what it's worth, Apple's black and white MagSafe cables may well report the same identity, since they're likely the same part in a different colour. A fake can also copy Apple's IDs. The screenshots will tell us whether anything differs between the three. |
|
|
I thought they might be identified because I read that apple released new firmware for the MagSafe cables, so I assume they would know what colour is what cable. |
|
@aldobalducci I checked this against the diagnostic data people have contributed from 332 Macs. For a MagSafe 3 cable, macOS only publishes two numbers, a maker ID and a product ID. There's no serial number, certification or rating like a USB-C cable has. Every MagSafe cable in that data reports the same pair: Apple, product 0x7800. So two genuine cables in different colours will look identical in WhatCable, and a third-party cable that copies Apple's IDs will too. There's nothing else macOS gives us to tell them apart. The one case that would show differently is a cable that reports no ID at all: the "Made by Apple" line would be missing. |
|
no worries, thanks for checking, its no big deal. I really only am interested in the usb-c cables.. but I thought Id test the MagSafe to see if that was an issue... :) |
|
at least it distinguishes which wattage charger its connected to, that's important. 👍 |
|
@aldobalducci that's right, and the charger side is where MagSafe gets most of its checking. For a MagSafe connection WhatCable shows what the charger offers, which option it's actually using (28V at 140W in your screenshots), and whether the Mac is charging, on hold or full. With Pro there's one more check: it estimates the charging path's resistance. That's measured from how the voltage behaves as the Mac's power draw changes. It's the one thing that could set a poor cable apart from a good one, because it measures behaviour rather than trusting the ID. It needs a few minutes of changing load on a single charger to give a result. Thanks for testing it anyway. I'll change the "Tracking" label so it stops naming a specific MagSafe cable it can't actually tell apart. |

ill let my Mac run down a bit then charge it and upload screenshots |

Hi everyone,
First, sorry for the long gap since beta.8. It's been over five weeks, and that's longer than I'd like to leave you without a build. Thanks for sticking with it.
Beta 9 is up: https://github.com/darrylmorley/whatcable/releases/tag/v1.5.0-beta.9
It's a big one, so the full notes are on the release page. The headlines:
What to look at:
"Looks fine on my setup" is as useful as a bug. Anything that looks wrong gets its own issue, linked here.
Thanks all!
P.S. If you can spare a minute, please run the diagnostic data contribution on beta.9: Settings > Community > Contribute Diagnostic Data, or
whatcable --test-kitin Terminal. It uses the new format, and a fresh run from your setup is the best way for me to spot problems early.All reactions
