What's does Photos Merge function do?
Photos on MacBook Pro Ventura. When I use the search for duplicates function, photos are displayed with different sizes. I know some are raw -vs- jpeg, but some are close in size but slightly different. What exactly will the Merge command do? Does it literally merge the 2 files together, not clear in the docs.
Also, when I synch music on Mac, why does it also want to synch photos. It doesn't make sense.
Thanks
MacBook Pro (2021)
