Photos Apple app, pictures & external drive
I 'd like to know whether, in order to relieve my iMac internal drive, I can transfer all my 56,000+ pictures (i.e. my PhotosLibrary) to an external SSD (connected by Thunderbolt 3).
I suppose that the Photo application itself should stay in the Applications files but how is it going to manage the transferred pictures?
