The Mac OS High Sierra release date was September 25, 2017. Its features and changes are mainly in the background of this release, so users won't see an awful lot of differences between Sierra and High Sierra. Mac OS High Sierra compatibility starts with late 2009 iMacs and Macbooks, and mid to late 2010 Macbook Pros and Macbook Airs. Tested on production 1.4GHz quad-core Intel Core i5–based 13-inch MacBook Pro systems with 8GB RAM, 256GB SSD and pre-release macOS Big Sur. Tested with pre-release Safari 14.0.1 and Chrome v85.0.4183.121. Performance will vary based on usage, system configuration, network connection. Preview of macOS High Sierra Apple. Apple has finally marked the date for the macOS High Sierra release, and it is happening later this month. MacOS High Sierra is the upcoming major operating system update that will affect Apple's Mac computer ecosystem. Like the iOS and other upcoming Apple software updates, the High Sierra will feature new.

Updated and republished for macOS 11.2.2; skip it unless you really really care about all the macOS releases. Originally published on November 14th, 2005.

Apple brings AirPlay 2 to Mac with the release of macOS High Sierra 10.13.6 Apple releases iOS 12.1.3, macOS 10.14.3, watchOS 5.1.3, and tvOS 12.1.2 Apple releases macOS 10.12.2 with auto-unlock. It is the successor to macOS Mojave and was announced at WWDC 2019 on June 3, 2019 and released to the public on October 7, 2019. Catalina is the first version of macOS to support only 64-bit applications and the first to include Activation Lock. It is also the last.

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 11.2.2, as of February 25th, 2021—the 146th release in total.

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.

Mac Os X Sierra Release Date

• Starting with the Public Beta and up through 11.2.2, there have been 146 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 February 25th, 2021 (11.2.2's release date), it's been 7,470 days since the Public Beta was released. So on average, we've seen some sort of update every 51.2 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.

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.
