Apple drops 'exclusion list' which allowed its own apps to bypass firewalls

The latest beta of macOS Big Sur has reportedly removed the contentious ability 
for Apple's own apps to bypass firewalls, and hide their network use.

Apple's release of the macOS Big Sur 11.2 beta appears to show that the company 
is dropping a controversial network feature. In the current public version of 
Big Sur, 56 of Apple's own apps and system processes can use the internet even 
when a user has blocked all access with a firewall.

Adding to the controversy, when those apps do access the internet, they do so 
without a user or any network traffic apps being able to monitor or report on 
them. Apple did this in part because of its Gatekeeper security system.

When a user opens an app, macOS "calls home" to check that this app is as it 
was authorized when the developer sent it to Apple. The idea is that if any 
malware has been added, Gatekeeper can detect that and stop the app launching.
