User Case

 

Almost all documents on my MacBook are synchronized with iCloud, with only a small percentage exempt. Only two document folders display the small grey cloud symbol, indicating they are not yet synced. Clicking on the cloud icon next to "iCloud Drive" reveals a message stating, "iCloud is not syncing - There are pending items to sync." This issue has persisted for months. Identifying the specific documents causing the problem is challenging, and I lack knowledge of how to manually trigger a synchronization.

Is iCloud Sync on by Default?

How Do I Force iCloud Drive to Sync on Mac
How Do I Force iCloud Drive to Sync on Mac

Mostly, iCloud Sync is on by default when you have a new Apple device. That means some data including your photos or files are synced from your device to iCloud by default. If there is some data on your device that you don't want iCloud to sync with, you can turn it off in the phone's "Settings", like turning off iCloud Photos or iCloud Drive.

iCloud Sync allows you to sync various types of data, such as photos, contacts, calendars, and app data, across your Apple devices. While some data like photos and app-specific data may prompt you to enable iCloud sync during the setup process of your device or when you install certain apps, it's not enabled by default for everything.
