Fewer false alarms, clearer readings
This release calms down trust and charging warnings that were firing on perfectly good cables and chargers, and sharpens a few diagnostic readings.
What's new
- Normal charging no longer looks like a warning. Benign charging states (a charger that simply is not the active one, expected lower-power negotiation) now show as normal status instead of alarming yellow warnings.
- A second charger reads as "standby," not "negotiation incomplete." With two chargers connected, the one not currently powering the Mac shows as a standby source instead of looking stuck.
- Trust signals reworded so genuine cables are not accused. A blank vendor ID, or a maker known from the community USB list but not the official USB-IF list, now reads as a calm note rather than a "counterfeit" warning. The warning is reserved for cables whose data is genuinely inconsistent.
- "No vendor" and "not read yet" are now distinct. A cable whose e-marker was not read on a low-power link now says so (it needs above 3A or a Thunderbolt link to wake), instead of looking like it has no identity.
- Correct data-link speed through hubs and docks. Readings now follow the actual Mac-to-dock link instead of the slowest link deeper in the chain, so a fast dock no longer under-reports.
- USB Billboard Alt Mode shown in Diagnostics, and the cable callouts are grouped at the top with consistent styling.
- More cables in the database (Thunderbolt 5 and 4, and others), plus refreshed Traditional Chinese translations.
