Generally good at supporting phones but not at supporting computers, a 5-6 years lifetime is unacceptable from an environmental point of view.

I experienced it last week when I turned on an old Mac with MacOS 10.7. It can't run anything. Everything that you download doesn't run anymore, Firefox and chrome are limited to some ancient version like 40 that breaks every modern website and due to some expired SSL root certificate you can't access any website that's using let's encrypt which is a big chunk.

And it's like this not from recently but at least 5 years, so it was put in a corner and never turned on anymore until last week

It can theoretically be updated to some newer version but the updater to 10.8 has been delisted from the store so you have to alternatively source that.

For comparison, a PC that was purchased the year prior to that Mac is running the latest version of windows 10 without any issue (except slowness due to the 1st gen core architecture)
