Hi colleagues,
I have a situation with 2 Macbooks M1, 1x A2337 and 1x A2338. I will post below the symptoms and what I have tried until now
- They both power on and display the exclamation mark 1 second after displaying the Apple Logo
- They both try to enter Recovery but after restart they loop in the step above, showing the exclamation mark
- They both enter DFU but are not recognized by the other computer. Also tried force DFU, bot have voltage on SOC_DFU_STATUS. Still not found by other computer in Apple Configurator or Finder, used more cables, TBT3 and TBT4
- Both USB ports on both laptops are stable, drawing 20.6v and 0.3a with no battery connected
- On the A2337 tried replacing the Thunderbolt Controller UF000 and also PMIC U8100. The problem remains the same.
