I ran into the same headache and found something that really helps. You can manage all your cloud storage from one interface using Commander One, which is a dual-pane file manager for Mac. It integrates different cloud accounts, so you can move, copy, or preview files without opening each service separately. It’s especially handy for OneDrive; the https://commander-one.com/onedrive-client-for-mac/ client lets you mount it directly in Finder-like panes. Makes syncing, organizing, and even batch operations much smoother. The interface feels intuitive once you get used to the two panes, and it reduces all that constant app-hopping.
