Photos Sync Across Icloud Accounts

John Varela

Mac OS 10.13.2 on brand new iMac, and 10.13.1 on MacBook Pro mid 2009.

I would like to sync the Photos library on my iMac with my wife's MacBook Pro.

This library is already synched with my iPad via iCloud, both machines using the same iCloud account.

My wife's MacBook is associated with her own iCloud account, not mine. I can't figure out how to get Photos on her machine to sync with my iCloud account, or even determine if that is possible.

Does anyone know?
