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

I had the same problem, and finally found a very odd solution. In my case, after a lot of frustrating work, I traced the problem to an old USB hub I was using on my new mac. Once I disconnected the old USB hub, the problem immediately stopped. In my case, it was surprising and very lucky to discover that the problem seemed to be associated with an attached electronic component. Hope this helps you.

I know all too well what you're going through. I bought my 2019 16" Macbook Pro in April and had this issue from day 1. After many days, and months of troubleshooting Apple finally agreed to replace the Macbook with a new one. It's not a software issue, it's a hardware issue. My new macbook works great. I just got the new one Saturday, June 27th. They also refunded my Apple Care and I repurchased it so the start date is on June 27th 2020. Good luck!

I have been trying to solve this for 3 weeks now. Apple is just being so hopeless. No answers from support and I have tried to organize callbacks from technical support and no call comes. Really feels like Apple is losing it. Particularly annoying given how much this MacBook cost. I’ve had it for over a month and haven’t really been able to use it. And AppleCare also seems like a total waste of money. Time to jump to a PC?

Jul 12, 2020 10:31 AM in response to philippg

This pretty much sums up my finds as well from my original post a few months ago. I agree that keeping on batter power works but is not acceptable as that defeats the purpose of a laptop.


i also tried to just log out and leave on login screen and closing the laptop but get the same error.


best I find is to shutdown so I don’t get the error, but I say again what’s the point of a laptop?


funny how my Mac desktop is on on 24/7 365 and sleeps all the time without any issues and it’s a 2013.

Jul 14, 2020 1:10 AM in response to LuigiZ

I think I found a solution, which at least suites me. I ran a command "sudo pmset -a standby 0", which as I understand disables deep hibernation. It make battery life shorter as people say, but for my MBP 2017 it is 1-2% per night – maybe it was even the same before, I never noticed it. Anyway, that is ok for me and I do not have crashes now. You can also google other settings for pmset.


PS If you want to bring standby back to default, run "sudo pmset -a standby 1"


Hope this helps someone

I'm having the same issue in a MacBook Pro Mid-2012 (A1278) running Catalina (10.15.6). The error occurs often when the computer is in sleep state and I disconnect it from charger and try to wake it up.

I have the same problem on an iMac 27" from 2018.


It typically occurs when I'm running Premier pro, Illustrator or InDesign and let it go to sleep. Sleep seems not to be a problem when simple programs like Word or powerpoint is running.

So this issue has been around for some time now and I originally saw it with High Sierra, which was when I upgrade my SDD to larger storage than what came with my laptop. I personally don't see Apple fixing this issue any time soon as it still happens with the latest macOS Catalina on my system.


My question to those still reading these posts, has anyone tired an older macOS to see if the problem existed on an older OS? I know that sounds funny, maybe even stupid, but I only use my old laptop for a quick surf to download a cooking recipe, check emails, things like that. Therefore I'm willing to try to downgrade the OS if it resolves the issue.


Just trying to make lemonade from some Lemons by Apple.
