DP1 occupied slightly more of the CD than the final DP4 release did, so you can count either: DP1 is 679.1 MB, DP4 is 676 MB. Mac OS X 10.0.0 'Kodiak': There were four different iterations of the Mac OS X Public Beta, but they all fit onto a single CD-ROM. You know what's missing from your big lists? Build numbers.Īnd because you asked nicely, here's some extra size data for the list: See Benton's comment below if you want a nicely detailed history of those early releases.Īnother special 'thank you!' goes to Mads Fog Albrechtslund, who provided updated PR links for all the major releases-most of mine had broken over the years. Ziebell (for providing some size values on very-old minor updates), and to Benton Quest (for providing size info on all the major releases up through Snow Leopard).

Feel free to contact me if you can help replace any of the '?' entries.Ī special 'thank you!' goes to Mr.

The '?' entry for Size on a given release indicates I was unable to find the size.

The largest (non-combo, non-main OS release) update was 10.15.1 at 5.3GB.

The smallest update was 10.3.1, at only 1.5MB.

(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 period at all is two days, the gap between macOS 13.2.1 and macOS 11.7.4.

The shortest time period between any two releases in the same OS generation 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 44 days.

As of Febru(11.7.4's release date), it's been 8190 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 11.7.4, there have been 186 macOS releases, both major and minor.

Some random notes, updated from the original post:

This has happened a few times over the years. This is to keep the version numbers in the proper order, even when an older OS received an update after a major new release came out. Some entries may appear out of chronological order (i.e. Note: The Days column reflects the number of days between releases. Ⓘ Leopard - First universal binary release Ⓘ Snow Leopard - First Intel-only release Ⓘ Lion - App Store only (USB stick later) Ⓘ Ventura (Taxes were too high in Santa Barbara?)
