Latest Osx Version

Latest

Updated and republished for macOS 11.6; skip it unless you really really care about all the macOS releases. Originally published on November 14th, 2005.

  • As updates that change the macOS version number become available, this article is updated to show the latest version of that macOS. To get a later version, install the latest Apple software updates.
  • Note: The headings on this list indicate the Macintosh System bundle names; the bullet points indicate the version of the System File included in that bundle. This is to make it clearer for people searching for specific bundle versions as opposed to System File versions. Finder File versions are not indicated. System 0.85 (128k) (1983) System 1.0 (128k / 512k) (1984) (also numbered System 0.97.
  • Since OS-X Mavericks (10.9) Apple have been releasing their OS X upgrades for free. This means if you have any version of OS X newer than 10.9 then you can upgrade it to the latest version for free. There are three ways you can upgrade. Download the Installer from Apple directly to the computer that you want to install the new OS X onto.
  • The latest version of macOS is macOS 11.0 Big Sur, which Apple released on November 12, 2020. Apple releases a new major version roughly once every year. These upgrades are free and are available in the Mac App Store.

Latest Apple Os X Version

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 11.6, as of September 13th, 2021—the 154th release in total.

Osx

The latest version of OS X that you can get running on a MacBook 4,1 (Early 2008 model) is Mac OS X 10.7.5. El Capitan will not run on the non-Aluminium 2008 models (Early or Late). I have verified this information against the Mactracker app (not affiliated with Mactracker in any way).

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.

Which Is The Latest Osx Version

Some random notes, updated from the original post:

  • Starting with the Public Beta and up through 11.6, there have been 154 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 September 13th, 2021 (11.6's release date), it's been 7,670 days since the Public Beta was released. So on average, we've seen some sort of update every 50.1 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 10.15.1 at 5.3GB.
  • 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…

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.
