ZDNET's key takeawaysThere are several options for your Intel-based Mac. First off, Tahoe is the last update Intel-based Mac machines will be getting. Also, make sure your Intel-based Mac runs Mojave or later (as any prior release will not work). Your Intel-based Mac may not receive new features or even a new version of MacOS, but it will continue to receive security updates until around 2028. Although you won't get a lot in exchange for that Intel-based Mac, you'll get something, and something is better than nothing.
