IOS 11 was released last Tuesday and MacOS High Sierra should be released on Monday. Be sure to check that your IOS-based photo apps (ie Affinity Photo or other) work OK before you need to depend on them. The same goes for the migration to High Sierra next week. As soon as you migrate, check that all your photo apps work. I have two photo apps that have problems running on High Sierra betas and Gold Standard beta. So those two apps will likely have updates early next week. Your mileage may vary.
