I reinstalled my system and attempted for weeks to get Time Machine to complete a first backup. Every time I started it, the progress bar would fill up about 60% and then stall, and eventually kernel panic if the system was left idle for hours. Never happened before I reinstalled, though I have had it randomly decide the backup is corrupt and it has to start over. macOS deserves a better first-party backup feature.

I have hit this too many times.
