Does macOS Reduce Motion change how Storage Studio looks?
Short answer: Yes. With Reduce Motion on, Storage Studio's Automatic setting chooses Light, which turns off live charts and animations. You can override it by choosing Good or Rich yourself.
Yes. When Reduce Motion is on in System Settings → Accessibility → Display, Storage Studio's Automatic setting picks Light, which drops live charts and continuous animations in favour of a calm, static interface. The hover reason on the performance label reads "Reduce Motion is on".
Everything still works the same way — only the motion goes. If you want Reduce Motion on for the rest of macOS but would like Storage Studio's live charts, choose Good or Rich yourself from the performance menu.
