Big Sur 11.6.1 is een pure beveiligingsupdate
De definitieve versie van macOS 12 Monterey is uit en ik ben er nog geen  bugs in tegengekomen op mijn 16-inch MacBook Pro uit 2019. Maar Apple vergeet natuurlijk de gebruikers van Big Sur niet. Daarom staat er een update voor iedereen met macOS 11 Big Sur op Apple’s servers klaar.

Zoals je in de (karige) release notes hieronder kan zien is deze update alleen bedoeld om de veiligheid te verhogen. Maar kijk je op de pagina waarnaar in diezelfde release notes verwezen wordt dan blijkt er een enorme waslijst aan problemen te zijn verholpen.
