Of Apple's new operating systems, only one has yet to be released. I speak of macOS Catalina 10.15which, according to Ma, arrive sometime in October. So far, no specific date had been vented, but today Apple itself may have revealed the mystery.
As highlighted by MacRumors, the company's Danish website specifically, the operating system page itself reads as follows in the part that highlights the Apple Arcade:
On the service page, however, there is no reference to dates, as well as macOS Catalina pages in other languages (including Portuguese).
The Apple Arcade on Mac obviously require macOS Catalina; therefore, if the game service is available at 4/10 on Ma computers, macOS 10.15 must also be available on that day.
O MacRumorsBut noticed that something plays against the date. Historically, macOS updates occur on a Monday or Tuesday. The last time a system update was released on Friday was with OS X Snow Leopard, 10 years ago!
Apple could, according to the site, launch MacOS Catalina 10.15 earlier this week and then launch Apple Arcade on October 4. However, it does not make much sense that it will not be available once the OS is released after all, it is already available for iOS / iPadOS and tvOS.
And you would bet on what date?

Apple, of course, has already tried to correct the information on its Danish website.
