Is macOS Big Sur stable enough to upgrade on your Mac?

macOS 11 Big Sur is now available to the public and it comes with a slew of exciting new features and changes. But is macOS Big Sur stable enough to install on your primary Mac? Read on for what the best option is for you.

macOS 11 Big Sur has been widely seen as the least stable of the major new Apple software releases this during the beta period from June until this fall.

Common issues have included graphical issues like problems with external display support, apps freezing, and random reboots. Stability has improved over the course of the beta period and Apple had longer this year with macOS Big Sur launching in November instead of September or October, but bugs and performance issues aren’t totally resolved yet.

Is macOS Big Sur stable enough to upgrade?

  • TL;DR: if you have any concerns about app stability, performance issues, and other bugs, hold out at least for the next bug fix update before upgrading (but maybe even a later update depending on your stability tolerance).
    • macOS Big Sur actually launched as 11.0.1 (after 11.0.1 RC 2 just two days ago) and the next build will likely fix initial issues with the first release available to the public.
  • If you have critical apps that must work, make sure to check for Big Sur compatibility before upgrading whenever you choose to (again initial release not recommended if you have crucial apps)
  • If you’re cool with initial bugs and issues, go for it!
  • Ideally, if you have a secondary Mac, install Big Sur on that for now

Finally, you could opt to install Big Sur on a separate APFS volume or create a bootable macOS Big Sur USB drive:
