Apple's latest Mac operating system, macOS Catalina, will see a launch sometime in October, the company announced today following its iPhone-centric event.

While iOS 13 and watchOS 6 will launch on Thursday, September 19, macOS Catalina will not be coming out at the same time.

test macOS 10
Apple has not provided details on when specifically macOS Catalina will launch in October, so it could come at any time during the month.

Apple has in the past staggered the releases of its new software updates, so it's not too much of a surprise to see macOS Catalina launching at a later date.

If Apple holds an October event that sees the launch of new Macs, such as the rumored 16-inch MacBook Pro, macOS Catalina could be timed with the release of the new machines.

I hope Apple support is prepared for all the customers 'upgrading' their reminders app and have it stop syncing with their Mac..

Good. Catalina betas right now are way too buggy, let the engineers take some more weeks to address the issues instead of rushing a release.

So mac event confirmed for October for 16" MBP, mac pro XDR display release date and more
so no modular Mac Pro release in September then, the website leak was wrong
I don't recall Apple having "release" events for OS releases after "launching" them at WWDC in the past.

Nor do they need Catalina to be released before they release the Mac Pro - just needs a point release of Mojave with any new drivers. Especially in the case of a "serious callers only" product like the MP: anybody with a serious pays-the-rent income stream that depends on their Mac who switches to a new OS on day one is... courageous. Plenty of applications aren't going to support Catalina on day one.
