mac wont wake from sleep after Catalina upgrade

I have tried resetting the NVRAM/PRAM and it does not resolve the problem. Safe mode also does not resolve the problem. I am using a 2015 MBP with OS 10.15.1 and the problem persists in safe mode. When I lock the screen and then wake the computer, I can see the mouse cursor and it responds to motion commands, but there is no login window and I can't get back in without a hard reboot. If I change the settings so that it doesn't lock when it goes to sleep, and then I put it to sleep, it wakes up just fine. The problem is with the login window.

When it is in this mode, the letter and symbol keys, <esc>, <delete>, <tab>, <enter>, <space>, and the arrow keys all turn the screen gray when pressed.

On a related note, I tried setting the login options so that it displays the login username and password entry box on boot, and that's also broken (seems to be trying to put the password into the username box, won't allow access to the password box) and won't revert back to list of names when set to.

Catalina seems to have broken the login functionality - or addressed security concerns to the point where the computer is unusable.

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/

Off topic but in relation to HP Scan, you can open the web UI for the printer and use the browser based scan. That works perfectly with both the glass and ADF. It's not as nice as using a dedicated app, but it works.

I have this problem on a brand new 2019 iMac 27" with Catalina installed on a new partition without any third party applications (just a clean install). The last Catalina update macOS 10.15.1 didn't fix it. The only way to wake up Catalina after sleep is to unplug the power cord for at least 30 minutes and try to turn it on again.

I'm using my Mojave partition until this is fixed.

My MacBook Air crashes during wake-up. Sometimes it crashed during sleep (can hear the boot sound with closed display). But only at night or after night. Maybe caused by changing to another date next morning ? No crashes if it wakes up the same day. This happened after changing the SSD (now 1GB). Before I updated to Catalina but is was stable until SSD change. Thanks much for any hint.

Another application was running with startup. I also canceled that from startup and now I have flawless wake up each time. Get rid of any apps that work in the background. Also any apps that run idle.

I have this same problem since installing Catalina. In fact, my iMac will randomly go into sleep mode on occasion. I found that a quick 1-second push of the power button on the back of the monitor will wake up the iMac without having to do a hard re-boot. The NVRAM/PRAM fix never works for these quirky bugs...

I was having this problem on a 15" MBP 2019, then again on the 16" 2019 MBP I swapped it for.

Basically, your Catalina install comes with a bunch of extensions for running RAID hard drives (most users won't ever do this). Something about at least one of them is broken. I haven't worked out exactly which ones cause the problem, but they can all be safely removed if you don't use RAID HDDs.

They can be found in MacintoshHD>Library>Extensions. Make sure you're looking the right right Library folder, you want the one on in Macintosh HD, NOT the one under your username. I made a backup of them just in case, then cleared out the following .kext files:

ACS6x

ArcMSR

ATTOCelerityFC8

ATTOExpressSASHBA2

ATTOExpressSASRAID2

CalDigitHDProDrv

HighPointIOP

HighPointRR

PromiseSTEX

SoftRAID

Since I was on a very fresh install, I expect these are all the ones which come with Catalina as standard. My machine has since been waking from sleep successfully and quickly every time, even with multiple displays and USB-C devices plugged in.

I have similar issue with MacBook Pro 13" 2017 model. It was all working fine and while at work, I went on a break for an hour and when came back it was like dead. It was not responding any keypress and I tried everything I could. Next day I brought it to Mac repair Center (Dr. Mac in Chandigarh), they reconnected the battery and it started just fine. They said not to put it in sleep mode for long but same day on work it went in sleep and after 10 seconds I tried to wake it up but i was late so it was dead again. I called the repair center and asked them what they did to fix it since I was not in the situation to bring it back to them. They said to reconnect the battery.

I opened the bottom panel and reconnected the battery, it started normally. I turned off sleep mode on battery or power adapter. I am currently running macOS 10.15.2 and no idea if it's a hardware or software issue. I am hoping it's just a macOS glitch and apple will fix it.

Almost same thing happens to my MB Air 11". I think it is related to the new SSD (I upgraded from the original 500GB to 3rd party 1 TB) which I installed at the same time that Catalina (from Sierra). But I don't see any clue on how to solve it.

I will pay attention to what you say about next day. But I see it is also battery-plugged related, or when the lid is closed for a long time.

Sometimes it shows the login window, but after writing user and pass and click return, it hangs completely.

My SSD is encrypted, what could make it worst to solve the issue. Thank you for any hint, too.

This statement is rubbish as sleep mode is part of macbooks value proposition. What my Win PC can and my Mac supported without any issues the last 5 years you better think before posing. I expect Apple to fix asap looking to the talent and monetary power they own. Cheers.

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!

I closed every app (including 3rd party) before going to sleep, but no success. I also went to Safe Mode and back to normal mode, without success.

I will try more things and back here in case something new happens.

Thank you

Maybe that's the original cause of the problem. But, why does the MBAir wake properly sometimes?

Even whether the problem is the blade, there is at least one good situation where sleep-wake works fine. I am training to find out when and why.

Thanks

I talked to some specialists from Mac service, they say, that Apple updated some kernels on old macs and you can use 3rd party NVME blades, but they granted it only for old hardware, not for new, they are not that stupid to allow 3rd party play in this game :)))
