Well, yes and no. It's true a system clock time being set badly can screw up the encryption services, and that's one thing that a dead internal battery will cause. I save installation packages for all past OSX systems, and to install them I often have to set the system clock way back to be within their certificates' (short) expiration dates. Sometimes I forget to set it back, and start getting strange errors like "this website's certificate is not yet valid" until I remember. But it doesn't cause panics. And you would be able to figure out if that's a problem by just checking your current system time. Since Apple started making all their laptops with non-removable batteries, I don't think they even include a separate internal battery anymore.
If you are getting true panics, you must have panic dumps available somewhere in the log area, and should be able to scan those. You should be able to examine your root certificates in Keychain Access; the app should be able to help you identify an untrusted one. Another thing that can cause reboots is benign — having the installation system set to install updates automatically, and some of these updates require a reboot. Usually the symptom of this is that you wake up to find yourself back at the login window. Still, the system logs would also identify this as a reboot reason. > On May 7, 2020, at 11:57 AM, Michael <[email protected]> wrote: > > Hmm.
