mac wont wake from sleep after Catalina upgrade

Hi Dimon1983,

Saddly, the command (sudo pmset -a hibernatemode 25) didn't work. In fact, make it worst. What means to me that using the disk as support when sleeping doesn't work.

That's why I'll try the mode 0 (sudo pmset -a hibernatemode 0) and het back with news.

Thank you anyway.

My NVME is Samsung 960 Evo... 1TB. I had to upgrade first before being able to install on it the OSX. I upgraded directly to Catalina (perhaps with High Sierra it would have been better, who knows). So that's right, but some glitch exists when sleeping.

I am determined to find out.

And, yes, Apple are anything but stupid at play!!

Eureka!!

I finally found the right solution to my problems. Let's summarise.

The problem:

Some Apple computers, like my MBA 11"has sleep wake failure with NVME 3rd party blades with Catalina (not tested with High Sierra). I was force to upgrade my Sierra version in order to be able to use the blade and install the OS.

Diagnostic:

The root problem is the hibernate function, which is related to sleeping. It failed some times, but the more time sleeping the highest probability to get sleep wake failure.

And that's because at some time, when sleeping, the system may go to hibernation mode, which implies that the memory is written to the disk (the blade) as an sleepimage file. And this causes the problem when trying to wake up.

First approach (workaround) to solve the problem:

The behaviour of sleeping function is set by "pmset" command via terminal. In my case these were my PowerManagementSETtings:

MBAJ:~ jorge$ pmset -g 

System-wide power settings:

Currently in use:

 standbydelaylow      10800

 standby              1

 halfdim              1

 hibernatefile        /var/vm/sleepimage

 gpuswitch            2

 powernap             0

 disksleep            0

 standbydelayhigh     86400

 sleep                10 (sleep prevented by sharingd)

 autopoweroffdelay    28800

 hibernatemode        25

 autopoweroff         1

 ttyskeepawake        1

 displaysleep         10

 highstandbythreshold 50

 acwake               0

 lidwake              1

note: hibernatemode 25 didn't worked for me, but thank you to Dimon1983 to put me on the right track to solve my problem.

To understand these parameters, use "man pmset" command. You will see how is the sleep-hibernate-wake relationship. Then, to avoid the failure I suggest to make it imposible the hibernation. This can be reached by this command:

$ pmset -a hibernatemode 0 standby 0 autopoweroff 0

But this is a workaround, a provisional solution, because hibernate is a good feature, which permits energy saving and more importantly, it prevents memory loss if the computer runs out of battery (when unplugged). So, here it comes the good solution.

How to solve the problem definitely:

The hibernation issue resides on the NVME driver, which seems to be on the Macbook ROM. In order to fix the issue, there is a way to replace that old driver with a new one.

This has been achieved by very good guru, called Cmd+Q, as you can see on this forum:

There you can find his comment and a link to a very good, and complex too, guide. Who said life was easy? I'll try in a near future, when I have some spare time. For now, I am always aware not to leave my MB without energy for so long.

Thank you to all of you to let me find the way to fix that issue.

George, I am glad you found the solution, because I dug out this info about pmset command from Russian site youroptibay - which helps people with 3rd party NVME disks to be installed on macs and who have problems with sleeping mode. I am glad that community helps to solve such problems. Good luck and thanks for great solution provided for other people.

Hey George, man !! You made it !! Outstanding.

Thanks so much for finding a solution, the Mac team was not capable or willing to do.

Now after frustrating months I recognize my Mac as he always was.

Cheers from Hamburg, Tom !

Hey GeorgePod, thanks for your excellent and detailed post!!

I'm also suffered from this issue for as long as I upgraded to Catalina, and cannot find any clue of how to fix it. (I also identified it's related to the duration my 2018 MBP sleeps, but cannot determined what's the root cause).

I now turned off my hibernatemode to 0 as you instructed, gonna observe how it works, also look forward to your future post if you tried the complex solution!

Thank you again for the effort!!

Hi tom,

Thank you for your congrats. I am glad some people may benefit form this "research", based as well on the good ideas coming from others.

Till the new issue, enjoy!!

(in fact I have another one, headphones doesn't work... it will be reported and commented)

Cheers from Spain

Hi YoEugene,

Thank you for your congrats. I am glad you finally seems to find the solution. Perhaps you will need to make further adjustments, no just the hibernatemode 0, but standby 0 and autopoweroff 0.

Jorge

Hi Jorge, your recommendation is still working. Thanks again for your help.

Unfortunately I am not an expert and wonder how to set the hibernation to Macs default again.

I hope that Apple provides a fix in future or that I can update the cards driver. Then I would like to go back to the initial setting.

Do you or somebody else know how to do this ?

Much thanks in advance and all the best from Hamburg, Cheers, Thomas.

Hi Tom,

The hibernate mode can be activated anytime simply by running that pmset command with the appropriate options/parameters. In my situation I will do after fixing the problem with hibernation on 3rd party blades.

But, if for any reason, you want to activate hibernation, the is the right thing to do, on a terminal window:

To check the actual Power Management configuration:

$ pmset -g

To set activate hibernation as it was before doing my recommendation (setting to 0 these parameters):

$ pmset -a hibernatemode 1 standby 1 autopoweroff 1

But, the sleeping-wake problem will arise again (on the MB Air with 3rd party blades)

Any other doubt, let me know. All the best to Hamburg (I'd like to pay a visit to that beautiful City some day)

Cheers

Jorge

Hi George,

I've already apply the:

$ pmset -a hibernatemode 0 standby 0 autopoweroff 0

But sadly these two days my 2018 MBP still got panic awakening :( Maybe there is other issue along with hibernatemode?

Below is my pmset -g information:

System-wide power settings:
Currently in use:
 standbydelaylow      10800

(My laptop is 2018 15" MBP macOS 10.15.3)

Thank you.

Eugene

I suffer from this blackscreen BAG after awaking MacBook Pro (15-inch, 2018) 10.15.3

I tried everything that was recommended in this thread and it always coming back :(

Also, I noticed that the touch-bar is off and if I connect the external display I can see the screen on it and gracefully reboot the MBP to get the stuff work again.

Any idea, I'm desperate here 🥴

@Apple please 🙏🙏🙏 address this annoying issue

This is a major headache. I have done two support call chats with Apple and I have tried all the recommendations: resetting the NVRAM, safe mode, test user and finally doing a new install. My iMAC desktop will not wake from sleep if it sits for over an hour or so. The only solution that works is to shut down when I leave my desk and start up whenever I want to use it. Changing to Catalina has been no end of headaches and I never should have done it.

I got the same problems. Done tons of research, tried every possible solution, contact Apple. Non of these solves the sleep/wake problem my MBP encounters. I don't know what's happened to Apple that they can be quiet on this issue for so long. Disappointed.

Did this ever get fixed? I am having the same issue with my MacBook Pro Retina with Touchbar. I even took it in and they thought it was the sleep wake sensor and replaced my logic board and still have the same issue. I have tried all of the fixes here and even re-installed Catalina...
