Just tried and this is completely true. What the heck.
As I said: That's a "feature" of macOS. It asks apple's server for every app launch whether it's allowed to open the app or not. And Apple is like completely offline right now. So apps won't launch as they get no answer from apple
 
YES! Very slow and unresponsive! Even more reason to do a clean install :D (once we finally can download...)
I downvoted this for a single reason, there's no need to reinstall macOS, I've said that uncountable times, been using OS X/macOS since the very first 10.0b, never reinstalled, always migrated/updated to a new mac by using a carbon copy of my old system to the new mac, never had major unsolvable issues.

Stop spreading nonsense, macOS does not need to be reinstalled/clean installed.
 
Got MS apps to work by killing network connection. Apps fired right up. Then reconnected Wi-Fi and all is well with MS apps.
 
Things are snappy again. For my own sanity though, anyone who upgraded from RC2 to the release build? I don't recall Apple showing actual APFS snapshots for OS updates, so does anyone see something similar in Disk Utility, or did I just mess up my install? So basically the com.apple.os.update-XXX snapshot it lists?

Em - no. What happens when you open an app when You are offline?

Even Linux needs a wipe and reload from time to time. I usually just reprovision new servers, then reinstall and configure the software. It helps that most of our software is developed in house and we don't need to worry about licensing.
 
On Mac Catalina, everything runs super fast. So is this a new feature of Big Sur that it pings the Apple servers every time?
