iCloud Sync
CMRSS uses iCloud (via CloudKit) to keep your feeds and folders in sync across all your Macs signed in to the same Apple Account. Feeds, folders, and read state sync automatically in the background. No setup is required — sync is always on.
Troubleshooting
If changes are not appearing on another Mac, make sure both Macs are signed in to the same Apple Account and have iCloud Drive enabled. Changes may take a few minutes to propagate.
