r/mac on Reddit: Security updates for MacOS Monterey 12.7.6
November 28, 2024 -

So I have a Macbook Air from 2015 which supports MacOS Monterey as the latest operating system. The laptop is a bit slow but does what it needs to do for light workloads.

When I search the internet for information about when MacOS Monterey goes end-of-support I get mixed results, but none from the official Apple website. Also I can’t find the exact date when Apple stops releasing security updates for MacOS Monterey.

I’m an IT professional and work in cybersecurity. I don’t mind working with old hard- and software, but I do mind working with operating systems that don’t get patched for potential critical vulnerabilities.

Does anyone of you know where I can find official statements from Apple that tell me the last date I can safely use my 2015 Air?

r/mac on Reddit: How well is Monterey (macOS 12) still supported in 2024 ?
May 6, 2024 -

I want to buy a new macbook to manage my music library in my living room. It will be connected to the Hi-Fi setup and will play music from Spotify, Apple Music (iTunes) and web pages (like web radios)

I've been looking at retina 2015 models :

I want the most recent mac possible but i'm also not super rich so i won't be buying anything new. I want at least a full Terabyte of SSD for my music library to fit properly and with some extra free space for the day spotify finally supports Lossless audio.

I'm also interested in it having the optical output which apple dropped by 2016

I see the 2015 will support monterey only, how long will i be able to use that ? Do you think it's possible to install something more recent on it without making it slow / loud.

Thank you all ! Have a very nice week ;)

If you are unable to upgrade your version of Mac OS the last version of Office that will work on MacOS Monterrey is 16.88, that is available on the table on this link to all the downloadable versions from the Microsoft servers.

On macOS Monterey 12.7.6, Microsoft 365 apps are supported only up to Office for Mac version 16.88/16.88.1 (and, per later guidance, 16.89 dated September 10, 2024). Newer builds require macOS Sonoma or later and will not install.

To get Microsoft 365 working on macOS 12.7.6:

  1. Make sure there is a valid Microsoft 365 or Office 2021/2024 license associated with the account. A current license is required to activate the older build.
  2. Download an older Office for Mac build that supports Monterey (for example, 16.88 or 16.89) from the Office for Mac update history page listed in the context:
    • Use the long table of downloadable versions on the update history page to select version 16.88 (or 16.89) for Office for Mac.
  3. Install the downloaded package on macOS Monterey 12.7.6.
  4. After installation, open any Office app and sign in with the licensed Microsoft account to activate.
  5. Run Help > Check for Updates once to move to the final supported build for Monterey (for example, 16.88.1 for Outlook and PowerPoint). AutoUpdate does not need to remain enabled because there will be no further updates for Monterey beyond that version.

If upgrading macOS to Sonoma or later becomes possible, newer Microsoft 365 builds can then be installed and updated normally.

February 19, 2026 - I'm still on macOS Monterey 12.7.6 with my 2015 15-inch MacBook Pro. It works fine, although many of the apps are stuck in older versions. I've installed macOS Sequoia 15.7.7 with OCLP 2.4.0 on an external SSD and it works without a hitch.
