It looks like something is missing. Maybe is an oversight from Apple. It looks like when we try to load an extension the com.apple.kernelcaches/kernelcache under PreBoot is not populated or not created. I've purchased an external SSD in an USB-C enclosure. I have two Mac Mini m1. One at home, another at my work. I wish I could turn off my office computer, unplug my ssd in home computer and boot my whole environment to keep working, and vice-versa. I wish Apple correct this. That would make M1 machines perfect.

I also have the same problem. I have installed a MacOS Ventura on an external SSD to preserve my internal SSD lifespan, and I cannot install a single app which relies on Kernel Extensions, for instance, pCloud, Tuxera, DriveDx, and so forth. Is there any solution available? Is this problem under Apple radar?
