I had to service the UltraFine 5K twice before realizing that using it to power the Macbook was killing it (seems power delivery overload). Hooking up the Mac to its own power fixed it.
Anyone else experience this?
I’ve been using one for over five years, exclusively with MacBooks which were always powered by the display. I haven’t had any issues with mine. (Except maybe once last year, when it wouldn’t turn on. I had to unplug the display from the power and plug it back in.)
The thing I heard was always killing them was the ports coming loose from people plugging and unplugging things all the time.
Could it have been that you were plugging and unplugging the MacBook?
Obviously that should totally work. I don’t know what I heard is correct, but I got the impression if you plugged a Mac in and just left it there it would be fine.
