Have a 2019 iMac arriving next week. My dilemma is how to best set it up with respect to my photos collection. I’ve been solely using my phone/iCloud for photos after my 2011 iMac died last year - it housed the main photo library but I did get everything on the cloud before the graphics card died. Is there anyway to access or transfer files from the 2011 even though it won’t load to the OS I have about 280GB in the cloud. How do I get all that on the internal of my new iMac? Simply sign in as usual and download? I was using optimization on my phone but want to get the originals back on drives. I am getting a 512GB internal SSD so obviously I’ll need external drives (is SSD needed for Photos library?). What’s the best setup process to run Photos externally?
