Where In The World Is Big Sur?
It’s right here, apparently:

However, I was referring to Big Sur the operating system. There have been two Apple events and quite a few products released over the past two months. As of this writing, there has been no official release. The beta program is still ongoing, with developer beta 10 and public beta 9 as the latest releases.
So what’s the hold up? If I had to guess, it’s waiting for yet another Apple Event sometime in the next few weeks. I would imagine this event would feature all things Mac, so it makes sense to wait for said event.
Personally I’m fine with waiting. Big Sur is going to be a big change, so I’m ok waiting for a stable release. It also gives us (Nisus) more time to be ready with compatibility updates for our apps.
In the meantime, I’ll keep using the developer beta and hope for the best.
