I’ve the next downside: I exploit Little Snitch to dam as regards to any connection to apple (please no recommendation on how necessary it’s to permit updates and so on, I do know what I am doing and why 
). This labored superb with Prime Sierra. I latterly arrange every other Mac with Large Sur, and all at once gui web get right of entry to is blocked after gadget restart. I will be able to ping by way of terminal, connection works superb. If I pause Little Snitch simply ahead of connecting to the web for the primary time, and reenable 1 minute later, everythings works superb, too – and continues to take action, till I restart the MacBook once more.
So briefly, Large Sur blocks gui web get right of entry to (i have attempted 5 other browsers and a few different apps) when positive startup connections are blocked. Does any of you’ve got any concept which connections could be the reason for this?? I have experimented with enabling and disabling plenty of them, however gotten nowhere up to now.
I am truly thankful for any tipps and concepts!

PS: This turns out like a grave privateness invasion to me… I principally can not use the MacBook until it is allowed to test in with apple!
