At least here in the Midwest at 12:45, macOS 12.0.1/Monterey (12.13GB download , iOS/iPadOS 15.1, WatchOS 8.1, HomePod 15.1, and tvOS 15.1 are now available to download.
Edit: I see that Big Sur 11.6.1 is also out. Perhaps there are iOS 14 updates as well but I no longer have devices on that release so can’t see them on the updates screen.
Does Apple provide an installer that I can copy onto an external drive? I have three Macs (which is not normal for me) and would rather not download the 12.3G more than once.
