Question about Applecare and Screen Sharing

[I Need a Drink]

I am having a problem with my Mac where it is signed into iCloud, but won't show as a verified device for Two Factor Authorization. I called Apple about the issue and after logging into and out of iCloud which did not fix the issue, the rep asked me to screen share. A popup showed up on the screen and he used a pointer to walk me through some things to see what was showing on my screen. Unfortunately, we were not able to fix the issue and he sent some info to engineering to see if they could find a fix and closed the session.

I'm paranoid about security, probably to a fault. Is this a normal practice for Apple to screen share and, after logging off, is there any way for Apple to still access my machine? I know there were some scams in the past about screen sharing involving popups on some websites, but I initiated the call and I know that I called the legit Apple phone number so I'm not worried about scammers. I just want to be sure this is normal practice and that there is no way, no remnants, for anyone to get back into my machine.

I had this problem on a computer that was running Little Snitch. Temporarily disabling Little Snitch and signing into iCloud allowed the device to become verified. I was then able to re-enable LS after that, and it still works for 2-factor verification.
Apple isn't going to be able to get into your computer without your knowledge, and they won't have left any backdoors for anyone else to get in there either, so you don't need to be concerned.

Open the Screen Sharing app, go to Preferences > Blocked Users, uncheck 'Allow screen sharing requests from Everyone.'
