How do I move some of my older photos to an external drive?
I am upgrading to a new MacBook Pro tomorrow, however it has a smaller storage than my current MBP. I currently have a Photos library containing all of my photos since 2011, stored locally on the computer. I have a 1 TB external drive that I would like to store the older photos on, while keeping the newer photos on the hard drive? What is the best way to accomplish this?
MacBook Pro, OS X Mountain Lion (10.8.4)
