Multiple anti-virus apps, and multiple cleaner apps. You want at most one anti-malware app added, and the built-in Apple anti-malware does pretty well. I generally don’t recommend add-on cleaner apps. Remove all of these add-ons, and see if things stabilize. Removing these apps per the vendors’ instructions usually works, but sometimes a wipe and re-install and migrate is required.
Growl is long retired, AFAIK.
Way too many kernel extensions for modems.
Lots of missing files.
A battery cycle count of 2 on a MacBook Pro from 2013 implies recent service, and which can then perturb other hardware.
With stuff going back to 2012, and all sorts of stuff missing, and the mix of anti-malware and cleaner apps, I’d be inclined to back up a couple of times, wipe, reinstall macOS Mojave, and migrate in the settings and documents, and then load current versions of the needed apps; to sorts-kinda start over.
But this is also a ~seven year old MacBook Pro, and a model no longer getting current macOS versions.
