We are going to show you how to do that, as well as point you toward a few externals storage devices that will work very well as repositories for your photo libraries.
What you need to do is to move photos from your Mac to an external hard drive. There is a simple solution that can be used whether you earn your living with your photos or just like to take a lot of pictures. We are making the assumption that you know how to move your photos from your iPhone to your Mac, and that your photo library is on your computer’s internal hard drive. Professional photographers and videographers are even more prone to running into a storage issue due to the size of their Photo libraries. After a while, the storage demands of your library can start to add up and cause lack of space issues on your internal storage device. If you are like most users, your photo library is an ever-expanding entity as you regularly add new images and never get around to deleting any of the older ones.
It is quite likely that you store digital photos on your Mac computer.
