NVMe Problems with Catalina

5 posts in this topic

Recommended Posts

I'm using Samsung 1TB 970 EVO (MZ-V7E1T0BW) NVMe. Everything has worked fine on Mojave for over a year. Now recently I made a clean install of Catalina and I'm having occasional panics related to NVMe.


Drive test is ok and I also flashed latest firmware but it's the same.


Is there some new NVMe problems in Catalina?

I wen't back to SSD, I never noticed any real world difference with Samsung SSD vs Samsung NVMe. Boot time went from about 20 sec with the NVMe to 8 sec on SSD, so clearly it doesn't work properly on macOS.
