Looking for advice... We are looking at getting an iMac as our family computer. This will be used mostly as our photo editing and organizing machine. We currently have somewhat of a mess of apple IDs. We have one that is used for purchases (a gmail account), and then my wife and I both have our own iCloud IDs that are used for our MacBooks and iPhones. We have not set up any family sharing. Should we create a new apple ID for the family iMac? If so, can that be used to link up all of the current accounts (gmail ID used for app purchases and the two iCloud accounts)? Will the photos on the iMac be able to be shared across all of the devices? TIA.
