Updated and republished for macOS 11.3; skip it unless you really really care about all the macOS releases. Originally published on November 14th, 2005.

Below the break is a table showing all major releases of macOS (previously Mac OS X) from the public beta through the latest public version, which is 11.3, as of April 26th—the 148th release in total.

Note: Click the ⓘ symbol to read Apple's release notes for a given update.

The following was culled from Apple's support downloads page, and as such, some of the dates may be off just a bit. If you know for certain that something is incorrect, please let me know and I'll get it fixed. (Scroll to see all entries.)

Note: The Days column reflects the number of days between releases.

Some entries may appear out of chronological order (i.e. 10.5 is shown on Oct 26, but above Nov 14 for 10.4.11). 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. This has happened a few times over the years.

Some random notes, updated from the original post:

• Starting with the Public Beta and up through 11.3, there have been 148 macOS releases, both major and minor. This figure includes the one odd macOS X release: 10.2.7. This version was only for the then-new PowerMac G5 and the flat panel iMac G4, and was never generally released.
• As of April 26th (11.3's release date), it's been 7,530 days since the Public Beta was released. So on average, we've seen some sort of update every 51.6 days.
• 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.
• The longest time period between any two minor releases is 165 days, which was how long we waited for the 10.4.9 update. (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 smallest update was 10.3.1, at only 1.5MB. The largest (non-combo, non-main OS release) update was 11.3 at 5.71GB.
• The '???' entry for Size on a given release indicates I was unable to find the size. Feel free to contact me if you can help replace any of the '???' entries.

And now, gratuitous graphics…

Releases by version number

Releases by year

A special 'thank you!' goes to Mr. 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). See Benton's comment below if you want a nicely detailed history of those early releases.

MAC OS support period and support end date

The actual support life cycle of MAC OS has not been announcedSupport end date is private

Actually, the OS patch provision range is decided,

• newest version
• One older version
• Two older versions

Until there is a serious security bug, a patch will be releasedTherefore, you can think that the above three versions are supported.

As mentioned above, support end date and OS lifecycle are not announced, so only product release date is described.

As mentioned above, MAC OS X has not announced the end of support date. For this reason, there is no formal verification method, and the support end date (and its version) is not listed when you check the Applewebsite.

I don't know if this fact should be pleasing or disappointing. This is because there is a danger that the MAC OS version you are using will soon become an unsupported version and security patches will not be provided.On the other hand, support for the MAC OS version is not clearly terminated, so even if your application fails, application vendors may find it difficult to escape and may be in a favorable situation for you.However, it is generally recommended to keep the MAC OS up to date. If your MAC is an older version, we recommend that you update to the latest version immediately.
