Syncing iCloud across Macs
My Macs and devices are all signed Q into the same iCloud account, but don’t seem to remain in sync. Changes made on one of my Macs seem to sync best with the others, but those from my notebook and devices don’t work as reliably. How can I fix this?
This is one of the most common A serious problems with iCloud. The best way to try to bring your Mac and devices into sync is, when they’re connected to the same Wi-Fi with a reliable and highspeed internet connection, check that each is correctly configured for that network, and able to access the shared services you use, then shut them all down. Bring them back up one at a time, allowing ample time for each to sync fully with iCloud before powering up the next one. If that doesn’t work, then it’s worth contacting Apple Support for iCloud to ensure there isn’t a deeper rooted problem in your account settings.
Devices tend to fall out of sync when they don’t have good and constant access to iCloud, such as when running on patchy mobile data connections. One way to work around this is to run a Content Caching service on a Mac that remains on and accessible whenever the devices are sharing its local network. The process is simple to configure, but does need a Mac that’s running and not asleep most of the time, and perhaps as much as 200GB of local storage, although this can be on an external hard drive. Enable this in the System Preferences > Sharing pane, and set it to cache All Content, including iCloud.
