Fortunately, there are a number of fixes you can try to get macOS, iPadOS, and iOS apps to sync with Apple's servers.
1. Reboot and wait
It might take some time for iCloud to start up when you make changes.According to some reports, this can be as long as 10 minutes.
You may find that just being patient will resolve the issue, but you can also try restarting all affected devices.Sometimes photos won't sync to iCloud until the iPhone is charged.If Low Power Mode is on, you should also disable it, as it turns off some power-hungry features.
On Mac, iCloud not syncing may be because you have disabled the Power Nap feature, which allows the device to check for iCloud updates while it is sleeping.To enable it, open the Terminal app on your Mac and enter the following command:
sudo pmset powernap 1
2. Check that you are using the correct account
This might sound obvious, but if you're not using the same iCloud account on both devices, they'll never sync properly.This may be why iCloud on the Mac is not syncing with the iPhone.Go to Settings > [your name] on iOS or Apple menu > System Settings > Apple ID on macOS to check which account is currently associated with the device.
Only one iCloud account can be signed in at a time, so make sure they match.If it doesn't match, you will need to log out of the incorrect account and log in with the correct details.
3. Make sure iCloud is working properly
Every service experiences downtime at some point.While most planned outages happen at night, when you're fast asleep, catastrophic failures or human error can sometimes bring down even the most reliable services.
To view Apple's current iCloud status, visit Apple's System Status page, look for the green dot next to iCloud Services.Any ongoing issues will be displayed at the bottom of the screen.
4. Make sure you have iCloud enabled for your app
You can change some elements in Settings (iOS) or System Settings (macOS) to solve the problem of apps not syncing.
On iPhone, go to Settings > [your name] > iCloud, then tap "Show All" under "Apps Using iCloud."Make sure the apps you want to sync are listed and enabled.You can also try turning it off and on again to force iCloud to sync.
Apps on your Mac that can access iCloud will appear in the "Apps using iCloud" section under Apple Menu > System Settings > Apple ID > iCloud.Click "Show All" to see the full list.
5. Check if the app has cellular network access
Having trouble syncing to iCloud using mobile data but not Wi-Fi?You may have disabled cellular network access for some apps.
Go to Settings > Cellular or mobile data, then scroll down to find the list of apps on your phone.Any application with the slider turned off will only run on WLAN.Try enabling data access for any apps you want to sync all the time, but be aware that this may increase your data usage.
At the bottom of the screen, you may also want to enable iCloud Drive.
6. Exclude date and time differences
When your iPhone's date and time are not up to date, you will encounter many problems.Many applications will simply refuse to connect to the Internet.To avoid these problems, you can set the time to update automatically, which keeps your devices in sync and avoids these problems.
On your iPhone, go to Settings > General > Date & Time, then toggle on Set Automatically.On a Mac, you can do this from System Settings > General > Date & Time, then toggle to "Set time and date automatically."Then, tick the "Use current location to automatically set time zone" checkbox.
7. Check if the synced folder is correct
For applications that allow you to customize which folder is used to store data, make sure the paths are consistent in both cases.If applicable, ensure that various iOS and macOS applications look for data in the same place.
8. Reset and restore your device
If none of the above methods help, and your device is unable to access or sync iCloud data at all, you may need to take the more drastic step of wiping your iPhone to fix any lingering issues.Before proceeding, make sure to back up your phone to avoid any data loss.
To reset and restore your iPhone, go to Settings > General > Transfer or Reset iPhone, then select Erase All Content and Settings at the bottom.
You can restore your iPhone from a backup you made when you reset your phone.Wait for the Apps & Data screen to load, tap Restore from iCloud Backup, then sign in with your Apple ID.When you're done, your device will be pretty much the same as you started with, except you'll need to add or authorize your various accounts again.
9. View support for a specific application
If your application uses data synchronization to transfer data between different platforms, there is a good chance that the developer will provide help documentation to help you solve the problem.Most of the time, the developers will be able to point out exactly which files and folders you should delete to resolve your issue.
Several apps, including Day One, 1Password, and Ulysses, include specific guidelines for troubleshooting iCloud issues.If the problem is with another application, search the web for specific help.
10. Use iCloud alternatives
Many apps will give you the option to use iCloud.If you can avoid using it, you can avoid many of the problems that plague the service.
For example, apps like Day One and 1Password allow you to use Dropbox.Plus, iCloud alternatives tend to give you more space and less hassle.Don't worry, you can still use other iCloud features like Find My and iCloud email accounts.
The best cloud storage alternatives include Dropbox, Google Drive, and OneDrive.
