I have an iMac which I originally used with my RAZR flip phone. About the same time that I got a 5s iPhone (a gift from a sister-in-law who was getting a newer iPhone and was tired of my indecisiveness), Apple added Photos. I hate Photos. The organization is horrendous. I try to use iPhoto when possible but it seems to be migrating my photos , in no specific order, to the newer 'shinier' Photos. Photos than makes these sleek little 'memories' that (a) I don't want and (b) make no sense. It will combine family pics from the 60s with garden pictures from 2016 and call that a memory. I need to figure out how to disable it. Plus I suspect that the memories increase the amount of storage needed. I guess if it's not one thing it's another.
