Sarcany, not doing the ZAP PRAM correctly, I thought not, I thought that was the one that you hold the keys down until you hear the CHIME, and then keep holding until you hear the chime again, I think we only did it once.
I have the Catalina Install USB Stick ready to go, and it works on my computer (Boots, and I can go as far as "do I want to install"
But since the Utility was there, I ran first aid on my two partitions and they came up FINE.
If we get to the point of doing all of above, and she boots into the USB Stick Catalina install, do you think it would be a good idea to run FIRST AID on both her partitions, before doing the reinstall of Catalina from the USB Stick?
Also , she told me, at me request , when I asked her if she had installed Chrome, that she deleted it, but not sure how, so I will have her uninstall that file you mentioned above, and direct her to this thread.
Thanks, So much
Tom
