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?
