I have a 2014 iMac running Ventura with opencore legacy patcher. It runs it as good as big sur hardware wise though each update something can break and you have to wait for the patcher to be updated to install updates. What I'm trying to say there no reason for apple to drop support for old macs so fast. iPhones and iPads gets long support but it's infuriating that they force people to buy new macs with so short updates cycles with the amount of obsolete garbage it creates for no reason other than to make more money. They are rich enough maybe share some of the lot with customers.
