Create new photo library on Mac that is not copied to iCloud
I have a large # of photos that I want to store on my Mac, but not have copied to iCloud. However, I also want to have access to my iCloud photos that I take on my iPhone. I found that I can create a new photos library (using option-click photos), but that is not a good solution because it doesn't allow me to access both my local and iCloud photos easily (e.g., I want to be able to copy between the 2, and quitting photos, going into options, changing library, etc is not the most user friendly process.)
Is there an easy way to do this?
