I plan to purchase a new IMac. I do not want to transfer all the pictures I have on this IMac to a new one. I do want to have access to the pictures though. Im talking 50,000 pics. They take up too much space. What can I do to keep just a few pics yet have access to the others?
You could have multiple photo libraries and keep one on an external drive. See: Designate a System Photo Library in Photos - Apple Support
and
Move your Photos library to save space on your Mac - Apple Support
