mac wont wake from sleep after Catalina upgrade

Nope: this has failed again and I am back to no wake. The watch connection was NOT the solution. I've done more experimenting and discovered that, most of the time, my machine will wake if I sleep with no other apps running. This seems particularly true if I am running Microsoft. I am able to wake from sleep with a few Apple standard apps running, but as soon as I turn on Outlook, Word or Excel I cannot wake. Tested with only Chrome on and it didn't wake, either.

Does anyone know: is there an extension or place I can look that would hold files related to third-party apps?

All, I used the advice above for my MPB and it seems to be working fine today. I had an old Core.kext from years back off a DynaDock or another display/port from past MBPs that also copied forward onto the new machine.

I can close the lid and wake it up, power button to go to sleep and the sleep from apple icon. I have not tried this on my Air but assume it will be the same as I used the same old hardware with it to use multiple monitors.

*I had posted the Safe Mode reboot had worked, but it lasted ~1.5 days and went back to the black screen...a lot of work for a bug many people seems to be experiencing....next stop is the Apple Store if this fails to hold-up.

AWESOME 👍🤓

As I wrote here or in another thread, I think this may perhaps be two-fold. One, a 32 to 64 bit issue with apple flipping that switch and no "sandbox" into which it would find those programs and dump them into for us to review for issue resolution (deleting). And two, older external device drivers that many of us had relied on and in most cases used for displays.

I seem to have mine solved as it seems you have...and I have not to reinstall Catalina...waiting out the install of the latest patch/update.

My laptop sometimes starts, sometimes no. WHY? HOW? WHEN?

Sincerely I don't know.

I use it, turn it off and it doesn't start again (not always).

BUT

If your Mac doesn't start up anymore, you can try this absolutely RANDOM AND TEMPORARY workaround:

1. turn on your Mac, when the "?" folder appears insert a BOOTABLE LINUX pen drive.
2. Use it for a some minutes*
3. Turn it off
4. Restart the Mac and, for mine, it's magically start up.

*30 minutes, 60 minutes

I DON'T KNOW WHY DOING THIS THE MAC STARTS but is the only way that I use when my mbp no longer start.

check out this thread link below. So far, deleting the extensions worked for me. Not sure if this will create new issues. But the computer wakes up from naps now at least: https://www.reddit.com/r/mac/comments/dfq969/mac_screen_wont_wake_from_sleep_after_catalina/

Do not be so rude, I am not putting garbage on anybody, but you would better learn the subject first prior to say such stuff for me!!! Authentic Apple blades are working perfectly, unless this problem with Catalina still exists, if you install a 3rd party none Apple NVME disk, you can forget about sleep mode forever!

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

I am still having the issue even after updating to 10.15.4. Although it is nice to know that it is an issue on Apple's end and not something else wrong with the laptop itself? I guess all I can do is wait for another update, or re-install macOS Sierra. Maybe I can get my money back for the logic board replacement...

I would like to participate.

I have an MacBook Air 2019, bought in Dec2019, with Catalina. Since the beginning I have the same problem, after a few hours my MacBook does not wake up normally.

If I just open it, nothing happens at all, it stays black. Forever.

When I open it and press the power button or other keys, nothing happens.

If I keep pressing the power button for about 40-60 seconds the user screen appears after some time. It's not a reboot, it just wakes up as it should be. With a delay.

I don't really need to keep pressing it, I just have to wait a minute or so, the I can push the power button and it awakes.

So my MacBook is only able to awake after quite a time and pressing the power button.

My friend recently got the MacBook Air 2020. If he opens up his MacBook, it's right awake, as it should be.

Together we checked the power management setting in the terminal, everything ist identical.

This is mine:

standbydelaylow      10800
standby              1
halfdim              1
hibernatefile        /var/vm/sleepimage
proximitywake        0
powernap             0
gpuswitch            2
disksleep            10
standbydelayhigh     86400
sleep                1 (sleep prevented by sharingd)
hibernatemode        3
ttyskeepawake        1
displaysleep         2
tcpkeepalive         1
highstandbythreshold 50
acwake               0
lidwake              1

I did the SMC and PRAM Reset and deleted the power management plist files as suggest in an other thread. Still the same.

Same issue for me ever since I upgraded to Catalina. Began April 10th. Have logged hours with Apple Support, done many of the solutions listed here (PRAM, SMC, new install of Catalina) and even brought in for repair. The Apple authorized shop was of course unable to replicate, but just to be safe replaced the "top case assembly." Just three days later, the issue arose again.

On hold with Apple Support again now, per my Mac guy's recommendation. He recommends pushing them to fix it. Frustrating...

Any fixes for those of us in this thread that tried the resetting of the NVRAM/PRAM?

Tried both suggestions. neither one worked for me:(

I have a J5 hdmi adapter, so I'm also going to deal with Trigger5Core.kext as others have posted.

These folders are empty

/Library/LaunchAgents & LaunchDaemon.

And in /Library/Extensions

I haven't these file

MTCTTrigger...

Trigger5core.kext

I hope in a fix in Catalina 10.15.1

See my post above with sudo command! It worked with mine IMac late 2013
