Macbook Sleep Wake failure in EFI (Failure code:: 0xffffffff 0x0000001f)

I have two macbook's, one model end 2018 and one model begin 2019.

They both suffer from the same problem with a fresh installation (also reset NVRAM, PRAM, SMC).


The crash reason: Sleep Wake failure in EFI

Failure code:: 0xffffffff 0x0000001f


I already contacted Senior Support for this and have a running case for both.


If you run into the same problem, please let me know here.

To trace down the problem more info of different devices can be useful.


If I get feedback that solves it, I'll post it here.



MacBook Pro 15”, macOS 10.15
