Hi Jake,
Thank you very much for advise, ECDV was the cause, Catalina upgraded with same Mojave Folder.. But i have weird issue now.. every reboot i have to try 3 times to boot into system, like screen goes black after acpi message, i have to force shutdown and try 3 times to boot. i am not sure whats going on? does anyone have same issue please help.
i have all my kext updated and are still in C\K\O Folder, should i move all of the kext to L\E?
