Are they that different? I find them very similar. A 10 year old mac will still work, **using the same software from 10 years prior**. Software changes a lot in 10 years, and companies will only support as far back as their budget allows.Computers are way different than smartphones. It’s completely normal (and expected) for a 10 year old computer to work. That’s the way it is for both Windows and Linux. Apple is the odd one out here. They treat their macOS updates like iPhone updates — a big numbered updates each year. And then developers have to target that specific update (and older ones if they choose, kudos to the ones that do). But the underlying code base is largely the same. It’s an arbitrary limitation by Apple.
Again, Apple stands alone on this. My example says it all. My same laptop computer runs modern software but only under the Windows partition.
Really though how often in history have 10 year old computers been truly useful for modern tasks? In 1995 a 1985 computer felt like a dinosaur. Same as 2005 vs 1995. Same as 2015 vs 2005. A decade in the computer industry is a paradigm shift. I’d say we’re lucky that the pace has slowed some to where in 2025 a 2015 computer is still relatively useful, but I wouldn’t say it should be a given that it would be
