catalina does not complete shutdown

Everything Shutsdown correctly in safe mode, I did the test. Maybe some process is keeping it from shutting down correctly.

I have a A1708 model. Upgraded to Catalina and this was the first issue I noticed. Accompanied by some distorted colors that the island wallpaper left before the screen went black, the island wallpaper appeared even if it wasn't the active wallpaper and the distorted colors would last about 1/4 of a second. I tried everything, even installing Catalina fresh without 32bit software and it would still freeze at shutdown. Only thing that would work was booting in safe mode, for some reason that kept some process from hanging at shutdown. I ended up going back to Mojave as it runs with no problems. I haven't tried Catalinas latest updates like the 10.15.1 or the 10.15.2 , maybe they patched it and didn't included it at the notes just to keep it a secret. Hope they fix this soon as I always like to keep my devices at the latest firmware.

Today I've contacted apple support fro release a feedback on this issue. Here, where and how, to Officially Report this Bug:

I am sending two feedbacks a day :-))

for me a simmular problem with shutdown Catalina ( MacBpro ).

Every time wenn i have used safari and firefox at the same time.

If i use only safari no problem with the shutdown. So is the cause firefox in conflict with safari??

The update does seem to have improved the situation for me, however, I have gotten used to not shutting down every night. It's nice not to have to wait an eternity for everything to fire up in the morning. Now I only shut down once a week. And if I have ANY kind of issue, I restart in safe mode..... then shut down and restart normally. For the time being, my iMac is problem free. (Have no illusions that this is permanent!)

Possible. I refuse to have any Google software on my machine due to their data mining propensity. You might consider removing Chrome and using, if you don't like Safari, Firefox. It's an excellent browser and very safe.

This is exactly the same issue I've been having since I updated to Catalina. Called support and they suggested a reinstall. Didn't solve the problem. I have a 2018 iMac; so, memory, hardware, etc. should not be an issue.

Upgraded to Catalina Again and did the test. So in Safe Boot turns off fine, after that, in normal boot I opened a couple of apps to make it look more realistic instead of just shutting it down real quick. Im surprised it shutted down normally except for the dock which still leaves a copy. Ive added a video so you can see. https://youtu.be/u4x9LMVmq00

My iMac (newly upgraded to Catalina)crashes on shutdown, screen goes blank but then error message / crash log next time I turn it on. Only had it in place for a few days, but crashes every time.

Well, when you get back up and running correctly I wouldn't reinstall Kaspersky.

Im having the same issue. Everything was just perfect before my upgrade to Catalina. (MacBook Pro Mid-2015)

I noticed first that it was slower than usual, almost like it was thinking a tiny bit where I had not experienced this before. When I went to shut down, got to apple icon, then hit shutdown... Then it removes all icons on screen, just has the island photo, and a little spinning circle set of bars. They then stop spinning and after about 1-2 minutes screen goes black and then immediately has an error message in many languages stating it had an issue starting up???? Says it was forced to restart. It then after 20 seconds goes to my very first log-in start screen.. From there I then click the power icon on lower right under where I'd enter my password. only way I can shut it down. Getting tired of this, and no idea how to fix. Furthermore it runs pretty slow now compared to before. Getting tired of companies making fixes and updates to better systems that work perfect.

same issue here. i tried to unplug the external HD before to shutdown, but it's same problem

mac try to shutdown but after 3 or 4 minutes of black screen it reboot again and i have to shutdown again

always that waste of time... too much annoying bug

Rather than drive myself nuts spending a huge amount of time researching and reading about possible "fixes" (that never end up working anyhow), I will end my frustration by not shutting down my Mac anymore! I will simply put it to sleep each night, wake it up in the morning, and wait ... and wait... and wait for Apple to do an update that gets rid of the Catalina bugs. NOTE TO SELF: Never again allow Apple to bully you into upgrading to a new OS until at least one year has elapsed since release! Why should the user have to suffer? Why doesn't Apple run sufficient tests until stability is achieved?

I actually noticed this in my testings, but the problem persisted. Thats when I knew it was some process that would end properly later backed up by booting in safe mode. If there's people still having this problem it means it has not been corrected in latest updates.
