iPhoto library migration to new iMac. How to get my 2nd iPhoto Library into Photos?
We transferred our files from old iMac to a new one yesterday. I opened Photos and there were my 3 iPhoto libraries in a list.. I selected the main one and during this morning it migrated them in to Photos. I have tried many ways to now migrate my other 2 iPhoto libraries in there too as it is not coming up with the same option. They are in pictures already on the new iMac, but I cannot click and drag it either? Any suggestions? Thanks in advance.
iMac with Retina 5K display
