This is because if iCloud Photos is turned off, nothing will be sent to the cloud and there will be nothing to sync with. Turn On iCloud Photosīefore you start, you will of course need to turn on iCloud Photos on your iPhone, iPad, or Mac devices. If you’re interested, then this is what you’ll need to do. It will take you a few extra steps compared to Mac users, but otherwise, it’ll probably just take you a few minutes to set up.
However, if you want to be able to view your iCloud Photos on your Windows computer, don’t worry because the process is rather simple. This is because for Mac, Apple has loaded the Photos app into macOS that automatically syncs with your iCloud account and you don’t really need to do anything else.
This isn’t necessarily the same for Windows. Photos you take on your iPhone are almost immediately viewable on your iPad and Mac computer if you have iCloud Photos enabled. One of the great things about being in Apple’s ecosystem is that everything syncs up nicely with each other.
