MacOS Tahoe will be the final version of macOS to support some specific Intel-based Macs.
APPLE has announced that the latest version of its Mac operating system, macOS Tahoe, also known as macOS 26, will mark the final substantial version of macOS to be supported on Intel-based Macs.
The final supported Intel-based Macs that will receive macOS Tahoe include the following models: MacBook Pro (16-inch, 2019), MacBook Pro (13-inch, 2020, Four Thunderbolt 3 ports), iMac (27-inch, 2020) and Mac Pro (2019). That means if you own one of these Macs, you'll still get access to all the features in the update later this fall when macOS Tahoe launches. The only exception is that anything that relies on Apple Intelligence won't be available, as those features are restricted to Apple Silicon machines.
It's been five years since the beginning of the transition from Intel to Apple Silicon. At the time, Apple stated that it would "continue to support and release new versions of macOS for Intel-based Macs for years to come." Intel-based Macs older than 2019 have already stopped receiving software updates, and it's now time for the last generation of models to get removed from the list.
Fortunately, Apple will provide security upgrades for these Intel-based Macs for three more years. That's pretty solid for machines that are already more than five years old.
