Apple recently declared the Apple Watch Series 4 and a 2019 MacBook Pro as 'vintage' products; meaning they are over five years old.
This classification impacts the availability of repairs and software support, potentially limiting their lifespan.
The Series 4, remembered for its significant design changes and pre-release leaks, is no longer supported by software updates.
Interestingly, the 15-inch MacBook Pro, the last Intel model, still runs the latest macOS, offering a longer functional life.
