After I upgrade OS my Macbook Air I got about 40 GB back from nowhere and have rely on 3th party applications for improving my productivity. I really love the upgrade until I insert a few SD cards and iPhones to my computer. The app called Photos always launches to search and display photos in the devices. It was super annoying for me and I tried to stop it from opening up. The only standard way to prevent it is to check do not use Photos on this device. HELL NO!! That’s not what I wanted. I want to kick it out of my computer since I don’t need it.
