macOS Sequoia Release Likely to Be the Earliest in Years

macOS Sequoia will be one of the earliest new macOS launches in over a decade, likely releasing within as little as just a week.

Internal Apple documentation obtained by MacRumors suggests that macOS 15.0 Sequoia will be officially released to the public by mid-September. The release dates of major macOS updates in recent years are listed below:

  • OS X 10.9 (Mavericks) – October 22, 2013
  • OS X 10.10 (Yosemite) – October 16, 2014
  • OS X 10.11 (El Capitan) – September 30, 2015
  • macOS 10.12 (Sierra) – September 20, 2016
  • macOS 10.13 (High Sierra) – September 25, 2017
  • macOS 10.14 (Mojave) – September 24, 2018
  • macOS 10.15 (Catalina) – October 7, 2019
  • macOS 11.0 (Big Sur) – November 12, 2020
  • macOS 12.0 (Monterey) – October 25, 2021
  • macOS 13.0 (Ventura) – October 24, 2022
  • macOS 14.0 (Sonoma) – September 26, 2023

The release of ‌macOS Sequoia‌ by mid-September this year would be the earliest since OS X 10.8 (Mountain Lion), which was released on July 25, 2012.

The new annual version of iOS has historically always been released at least a week before the new version of macOS. Sometimes, Apple leaves a considerable gap between the releases; in 2020, the company left nearly two months between the release of iOS 14 (September 16, 2020) and macOS Big Sur (November 12, 2020).

New major versions of iOS are always released before the launch of a new iPhone lineup in September. This year, the iPhone 16 lineup is expected to launch on Friday, September 20. As a result, ‌macOS Sequoia‌ could not only be the earliest macOS release in over a decade, but also the first simultaneous iOS/macOS release ever, or even the first time a new version of macOS has been released before the new version of iOS.

Apple is almost certain to share more information about the release of iOS 18 and ‌macOS Sequoia‌ at its event on Monday, September 9, where it is also set to unveil the ‌iPhone 16‌ lineup, new Apple Watch models, and the fourth-generation AirPods.

It also has the least amount of new features in years, probably since Snow Leopard.

Anyone else feels really nostalgic about how MacOS and iOS used to look like 15 years ago? I mean, dwelling in the past can be a fruitless exercise but don’t you wish there was a “skin” or something we can apply??

Nope, I am expecting a hot mess, but hoping for a stable release. I've been disappointed for years, so I don't expect anything different.

Overall there isn’t really much in 14.0, and 14.1 isn’t that much better. Apple really put their focus on AI in this release, and looks like they’re really far behind. So, it looks like they’ll just be releasing Sequoia unfinished, just to buy time while they work on getting the AI stuff done. That doesn’t look like it’ll happen until 14.2.

The .2 releases generally release from December and January (usually January), with as late as February. Since 14.0 is looking to be released early (14.0 it’s very much finished, and all the focuses on 14.1 and 14.2 right now), I’m going to guess that we will get 14.2 in December, maybe late November for lucky.

So while Sequoia may be released early, the real bulk of the features promised are looking to be released very late.

I’m a huge proponent of Apple needing to stop the yearly OS upgrade cycle, at least for macOS. Forcing the development team to release something new and great once a year is drastically diminished the overall quality and stability of the operating system, and has generally led to overpromising and underdelivering on features. I’m still running macOS 12 and 10.15 on some computers, because they were much more bug free than 13 and 14. My Mac studio on 13 and 14 has been a nightmare. it doesn’t appear that they’re going to fix the issues in 15, so I may roll back to 12 (but that’s going to be a pain).

Apple really needs to move to a year and a half to two years cycle, and the next release should be all about bug fixes and performance. Considering that the marketing people are mostly in charge of the company now, I don’t think there’s a chance of that happening unless they market it to us as a feature, perhaps when they drop all Intel Support. Similar to how it worked with 10.6 Snow Leopard.

I’m really hoping they get this figured out, I’m really hoping they get this figured out, Linux doesn’t quite do it for me, no matter how hard I try to use it, and Windows is a pile of garbage.
