#Apple macos versions in order mac os x
(Tecnically, it's actually the 192 day interval between the Mac OS X Public Beta and version 10.0, but I'm counting from the official 10.0 release.) The longest time period between any two minor releases is 165 days, which was how long we waited for the 10.4.9 update.The shortest time period between any two releases is six days, which is how quickly the 10.15.5 Supplemental Update 1 came out after the 10.15.5 release.So on average, we've seen some sort of update every 53.0 days. As of September 23rd, 2020 (macOS 10.15.7's release date), it's been 7,315 days since the Public Beta was released.This version was only for the then-new PowerMac G5 and the flat panel iMac G4, and was never generally released. This figure includes the one odd macOS X release: 10.2.7. Starting with the Public Beta and up through macOS 10.15.7, there have been 138 macOS releases, both major and minor.Some random notes, updated from the original post: Ⓘ Leopard - First universal binary release
