## 核心特性

– At-a-glance headline:** Thunderbolt / USB4, USB device, Display connected, Charging only, Slow USB / charge-only cable, Nothing connected
– Charging diagnostic:** when something’s plugged in, a banner identifies the bottleneck:
– “Cable is limiting charging speed”* (cable rated below the charger)
– “Charging at 30W (charger can do up to 96W)”* (Mac is asking for less, e.g. battery near full)
– “Charging well at 96W”* (everything matches)
– “Battery full, not charging”* (plugged in, battery full, so the Mac isn’t drawing power)

## 社区数据
