Fair point. I was talking about iOS devices which are much more locked down than macs. As i see it there are two issues with no-longer supported macs:
1. The security issue i mentioned earlier applies to macs. It’s a bit easier to mitigate because an older mac can run a newer non-system-linked browser. But e.g. firefox is dropping support for 10.14 (released in 2018) this year (https://support.mozilla.org/en-US/kb/firefox-users-macos-101...)
2. If you keep your os up to date as long as possible, new features will drag performance down to the point of being nearly unusable. So you’re forced to tradeoff between security+features and performance.
Of course, with a old mac you can always install linux to extend its lifespan… but that’s not thanks to apple
