If you have a Mac that is signed into the same iCloud account as your iOS device, you can find the documents that you have saved on iCloud from your iOS device.
- Switch to Finder
- Use the Go to Folder menu item in the Go menu
- Enter this in (without quote marks): "~/Library/Mobile Documents/J5L75SL484~V6R4297QYC~com~DanSchimpf~MacJournal/"
- Press Return.
This will jump to a folder that should have your MacJournal documents in it. You can then copy them somewhere else for backup purposes. You should not open these files directly or use them from this location without making a copy somewhere else.
