I was having this problem on a 15" MBP 2019 with the Pro Vega 20, then again on the 16" 2019 MBP with the 8GB Radeon 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.

Same on my brand new 16" MacBook Pro.... Pretty much on every sleep. I hate Catalina! The worst software from Apple ever... I also have this problem = And after having spend since November with Apple support, and countless Tests, they sent me to the Genious Bar - not so genious, as it happens on all my macs that run catalina, and covid 19 has genious bars closed... https://discussions.apple.com/thread/250726535

This is happening on my brand new MacBook Pro 16", which came with Catalina pre-installed. Crashes every single time on wakeup and several times a day at random for no obvious reason. I've tried running only Apple apps and the same happens, so that rules out third party s/w issues. There are no peripherals attached, so it isn't that either. Very frustrating, and making me regret buying a new PB that can't be downgraded to Mojave. Come on Apple: up your game!

This happens to me too on a brand new top of the line Macbook Pro 16". I just started noticing it since I started using an external monitor. It seems to do with having stuff plugged in. Catalina has really been a huge disappointment in terms of stability.


I've sent multiple reports to Apple. How are they not investigating and fixing this? Incredibly disappointed for a $5000 computer.

My system is fixed.


I am using 10.15.5 and my MBP16 has become perfectly stable. I've been doing photo work again and no problems with it at all. I've had 3-4 weeks without an issue. If you review my May 22, 2020 post above you will see the steps I used to gain stability before the 10.15.5 update. When it was released, 10.15.5 installed without issue and has been solid since day one.
