Microsoft is doing about what Apple does except more as a one time thing. 7th Gen Intel chips launched in early 2016. These machines will lose support for Windows 10 in October 2025. Most Macs are supported about 5 years for full OS updates and about 2 more years of security updates though this all varies a bit OS to OS version.

As an example, when macOS 12 (Monterey) reaches end of life in a few months, MacBook Pro pre-2017, MacBook Air pre-2018, iMac pre-2017, and Mac Mini pre-2018 will all be unsupported and no longer receive security updates.
