Microsoft's Windows 11 operating system has introduced stringent compatibility requirements, making many PCs, some as young as six or seven years old, ineligible for security updates and upgrades. Apple's MacOS update policies are similarly restrictive, with security updates provided for the three most recent versions. When a new version is released, older systems may become unsupported and stop receiving updates. The upcoming MacOS 26 Tahoe is expected to launch in September, at which point MacOS 13 Ventura will cease to receive updates, affecting older Macs. Unsupported models include MacBook Air, MacBook Pro, or Mac Mini from 2017 or earlier, and iMac and Mac Pro models from 2018 or earlier. For Windows PCs, compatibility with Windows 11 generally requires a CPU released in 2019 or later, though some older Intel CPUs may qualify. Microsoft offers a PC Health Check app to assess compatibility, and users can bypass certain checks to install Windows 11. Windows 10 users can pay for security updates for up to three years after support ends in October 2025, a feature not available for Mac users. Security updates for both Mac and Windows PCs are typically available for eight to ten years after the release date.
