Norton Internet Security install fails on Kernel Extension permissions
I am having trouble installing today's version of Norton Internet Security on a Mac Mini ( late 2014) with a newly upgraded version today of Mac OS Catalina ( 10.15.1). It is failing on asking me to give permissions for a Kernel Extension, but giving me no choice of Symantec ( or anything) in the permissions window. I see other Mac users have run into this problem!
What's frustrating is that it seemed to work and I even ran Quick Scan, but then it's decided not to work any more. I see it described in a recent post on Catalina and temperature problems on this forum which I can't look up right now because I'd lose my place and it took me about 20 tries to get the "make new post" button to show up at all, ( when I selected to make a new post from the link at the bottom of the search, it took me to my profile instead. Agghhh!! )
History of how I got to this state follows.
It is possible that many prior versions have not been fully removed from the Mac by the symantec removal tool 5.53 that I found on the mac (it's not my mac)
If all else fails I will just drag everything I can that says Norton in the trash and start with a new download, but as a heavy Windows user that action seems dangerous and risks leaving pieces around that I didn't see, so I have not tried that yet. Maybe there is a new, better, fancy removal tool ( almost certainly ) and maybe I should get that. We shall see.
In any case, I ran that removal tool when the download complained about a prior version existing. It seemed to work, in fact I got normal operational screens and selected Quickscan and that worked, then I selected FULL SCAN, but after 20 minutes with a flashing progress bar and zero files scanned I tried Pause and Cancel, neither of which worked so I closed the window and rebooted the machine. I guess that was a mistake, although I think it was already doomed at this point.
Anyway, now if I click on Norton it complains that it needs to be rebooted, and when i do that it comes up and wants to do an installation and when I select that choice, it dies when trying to make a Kernel Extension, which it apparently does not have permission for, but it also doesn't provide it's name in the right place for me to GIVE it such a permission.
note -- i understand how the permissions work. Earlier in the installation there were TWO symantec permissions it wanted and i unlocked the right little lock and selected to authorize other apps and picked symantec and it worked, or seemed to.
So i'm stuck. Probably in an unrecoverable state, or certainly in a state unfamilar to developers.
Maybe my question is really, how can i clean off everything that norton owns and try again from downloading onward? But if there's an easier way to save a few hours and fix what i have i'd love to hear it.
screenshots are on the mac and I'm posting from a different computer so they are not attached. This is just the very normal screen used to give permissions to new developers to access the Mac, so not much info on them. It worked an hour ago.
