Apple recently came out with their newest and revolutionary version of macOS called macOS Big Sur. The new macOS has updated to unique capabilities and elegant friendly interface rather than the versions (Catalina, Mojave, High Sierra and Sierra). Since it is on beta stage it is only available for paid developer accounts.
It means only the paid Apple developer accounts can upgrade and experiment with the new macOS Big Sur. Whereas, non-developers has to wait for public beta or the full version which is expected to come during October.
Why it is restricted to developers?
The answer simple and obvious. Developer beta is for professionals who could understand and point the bugs so Apple could rectify the bugs and make it perform better. However, it is the least of the reasons and there could be plenty of other causes.
The good thing is that macOS Big Sur beta-1 is not only limited to professional developers, rather anyone can sign up for developer account for only 99$ yearly and explore the new macOS.
