MacOS Big Sur Major Flaw: Apple Apps Can Bypass Its VPNs and Firewalls, Here's How

The latest macOS Big Sur is currently facing a major problem against Apple apps. The tech giant manufacturer always claims that it is prioritizing the user's privacy before any provided services.

However, Apple's claims usually don't match what they are providing in their products, such as MacBooks and iPhones. This is proven tested because right now, Apple applications can breach Big Sur's firewalls and VPNs.

A Twitter user under the name @mxswd first spotted the issue in October.

"Some Apple apps bypass some network extensions and VPN Apps. Maps for example can directly access the internet bypassing any NEFilterDataProvider or NEAppProxyProviders you have running," she said.

Big Sur's issue is now confirmed

The issue was not only revealed by the Twitter, it was also confirmed by Patrick Wardle, a security researcher at Jamf.

He said that previously, Network Kernel Extension or kext, can be used to implement a comprehensive macOS firewall. Ever since Apple disapproved kexts and replaced it with Network Extensions, the company's apps began to bypass the filtering system.

According to The Next Web's latest report, the researcher discovered that the issue is true since the Mac App Store on the latest macOS breaches any firewall.

Why should you upgrade to macOS Big Sur?

Since the latest MacBook system is suffering from VPN and firewall breaches, there are several things to check before you upgrade to macOS Big Sur.

According to 9to5mac, you must make sure that Big Sur is compatible with your apps, especially the critical one. However, if your device is already okay with initial bugs and issues, you can already get the latest system.

You can also upgrade your secondary MacBook to macOS Big Sur if you're not using it all the time.
