OK - I have a 2017 MacBook Pro and a 5,1 ... but as far as the environment goes, the 5,1 chews a lot of CO2 compared to Apple Silicon. And it's the 3rd party software that demands the latest security upgrades, and those will stop in a couple of years for Intel Macs. That's not really Apple's fault from various perspectives. And Apple's hardware profits likely comes from phones and notebooks. Which benefit from Apple Silicon.And the unified memory benefits power consumption and weight - both phone and notebook benefits. I would be happy with Apple if they had a policy to upgrade Apple Silicon storage and memory. Since they do not, it makes me angry at Apple. I'm uncertain though about them being environmentally evil, because I reckon the rest of the intel/AMD boxes are much worse environmentally than what Apple produces.
