MacOS tends to follow iOS/iPadOS by several weeks, often a month later. I would guess that macOS will not go into weekly releases until next week or the week after. I expect the next macOS beta to come out tomorrow (Thursday). While iOS still has three releases left before the expected iPhone September event that will likely be on September 14, the new MacBooks will likely not be released until October or November. My guess is that macOS will come out sometime in October, which may or may not match up with the M1X announcements. November seems a bit too long to wait for macOS final release.
