Hey @poil66, I had the same problem not knowing why then it came to my mind I upgraded my RAM to 128Gb and used RAM modules from different companies a absolute no go. So I took out 64Gb now I have left 64GB in my iMac from the same company. Never had a Crash again.

I updated to Catalina 10.15.4 this morning, and in the 2 hours gap I was using it, I already had to restart my computer 3-4 times. It just shuts down, sometimes with a woof of air. (English isn't my maternal tongue sorry for the mistakes)


I had to restart the update too, about 3 times, because the computer was shutting down by itself while making the update (!!!) That should have made me think twice about persevering with the update...


I've been bottle fed by MacIntosh, than Apple practically since I was born, and I never ever encountered this kind of problem. It actually getting on my nerves because this kind of crap never happens with Macs!

Found this on another thread. I think this is it since I used a timer to see when the computer would shut down and it was exactly at 15 min so:


"Here's the fix, and Apple needs to fix this on their side too!


Go to System Preferences | Security & Privacy | Click on "Advanced" on bottom right (unlock padlock first) | Uncheck "Logout after 15 minutes of inactivity"


This was the fix, i no longer have the rebooting happening thankfully. I've had this Macbook Pro for 6 years, never knew that this option even existed in all these years! It somehow got enabled with 10.15.4 upgrade?!"
