Real question. I would like to know what drives you to hate Apple? (In terms of privacy of course because in terms of price it’s another story).
It depends on the chipset. The big changes in chipset have been the big barriers for Mac upgradability. My father ran a 10 year old MacBook that was still running the latest MacOS until he found that his 4GB of RAM wasn’t going to be enough and bought a new one (without talking to me first). I had a PPC MacBook that ran on the latest MacOS for about 6 years after Apple switched to Intel.
