Planned obsolescence: the other day I was setting up a refurbished MacBook air from 2017. It officially runs only up to macOS 12. I wanted to install apple's productivity suite iWorks (pages, keynotes, numbers) on it.
But the AppStore said I would need macOS 13 to download and install it. Why the eff doesn't it allow me to install an older version of those apps, and why does the 2017 not support macOS 13?
So I installed Open core Legacy Patcher, built a macOS 13 installer. Installed 13 with absolutely no issues and finally was able to install iWorks.
Any non versed or risk taking user would need to buy a newer Mac... good job apple.
Conversely I have a dell xps from 2018 that run very well with fedora atomic (kde). I upgraded the SSD, WiFi card and replaced the battery. Should easily last me another 5 years
