iCloud Integration
Diagrammix3 integrates with iCloud Drive, allowing you to sync your diagrams across all your Mac devices automatically.
iCloud Drive Overview
When you save diagrams to iCloud Drive:
- Files are automatically synced to iCloud
- Access your diagrams from any Mac signed into your Apple ID
- Files are backed up to iCloud
- Changes sync automatically when connected to the internet

- Active Apple ID
- iCloud Drive enabled in System Settings
Check iCloud Status
- Open System Settings (or System Preferences on older macOS)
- Click Apple ID
- Select iCloud
- Ensure iCloud Drive is enabled

Sync Status
Checking Sync Status
In Finder, look for sync indicators next to files:
| Icon | Status |
|---|---|
| Cloud with arrow | Downloading from iCloud |
| Checkmark | Fully synced |
| Dotted cloud | Available in iCloud (not downloaded) |
| Progress circle | Currently syncing |
Force Sync
To ensure a file is synced:
- Right-click the file in Finder
- Select Download Now (if cloud icon visible)
- Wait for the download to complete
Handling Sync Conflicts
If you edit the same document on two devices without syncing:
How Conflicts Occur
- You open document on Mac A
- You open the same document on Mac B (offline)
- You make different changes on each Mac
- Both Macs reconnect and try to sync
Resolving Conflicts
When a conflict occurs, iCloud creates a conflicted copy:
- You'll see two versions of your file
- One named normally, one with "conflicted copy" in the name
- Open both versions
- Manually merge changes or choose the correct version
- Delete the unwanted version
Avoiding Conflicts
- Sync before editing: Ensure files are fully synced before working
- Sync after saving: Wait for the sync indicator to show complete
- One device at a time: Avoid editing the same file simultaneously
Working Offline
You can work offline with iCloud files:
- Files you've opened recently are cached locally
- Make changes while offline
- Changes sync automatically when you reconnect
Making Files Available Offline
To ensure a file is always available:
- Right-click the file in Finder
- Select Download Now
- The file will be kept locally
Storage Management
Checking Storage
- Open System Settings → Apple ID → iCloud
- View your storage usage
- Click Manage for details
Optimizing Storage
macOS can automatically remove locally cached iCloud files when storage is low:
- Open System Settings → Apple ID → iCloud
- Enable Optimize Mac Storage
Note: This may require re-downloading diagrams when you need them.
Troubleshooting
Files Not Syncing
- Check internet connection
- Verify iCloud Drive is enabled
- Check iCloud storage isn't full
- Restart Diagrammix3
- Sign out and back into iCloud (last resort)
Slow Sync
- Large files take longer to sync
- Check your internet connection speed
- Wait for background syncing to complete
Missing Files
- Check iCloud.com to verify file exists
- Look in the "Recently Deleted" folder
- Check other devices for the file
Tips
- Name files clearly: Good names help identify files across devices
- Organize with folders: Create a Diagrammix folder in iCloud Drive
- Regular backups: Export important diagrams locally as backup
- Check sync before closing: Ensure changes are synced before shutting down
