I am currently using one of the oldest platforms supported by their latest OS, late 2012 iMac core i7. Whew! Just made the cut. Guess that means this is the last major version of macOS this beast will ever run. Feels like hearing your pet is dying of cancer. Kinda. Sorta.
This is why I am trying to retreat from the Apple ecosystem. I want my technology to last, and I can’t do that on devices that simply get “dropped”, and become useless, after just 5 years. Ubuntu Linux LTS releases, which come out every 2 years, are each supported for 10 years, and run nicely on most popular hardware. Thank you very much.
