I have a macbook pro from my father from 2012 that work just fine, but I have to patch the bootloader and insert some kexts to run the latest version. It works just fine, but Apple don't want it to work. My daughter has an apple watch se that they also stopped updating after just 3 years, so now the LTE on it is useless as the carriers here require a newer version. She's getting the pixel treatment when it's time to get a new phone.
