The problem you're facing is that photos and videos taken on your iPhone are not syncing correctly with your Mac through iCloud and macOS Photos. While you can see previews of these files on your Mac, you can't open or modify them, and you get an error message saying the resource is not available. However, you can still access the same files without any issues on your iPhone or through iCloud's website.
To try and fix this issue, follow these steps:
- Make sure that iCloud Photo Library is turned on both on your iPhone and Mac.
- Check that both devices have a stable internet connection.
- Ensure that your iPhone and Mac have the latest software updates installed.
- Try restarting both your iPhone and Mac to see if it resolves the problem.
- Check if you have enough storage space available on both your iPhone and iCloud.
- Attempt to repair your Photos library on your Mac to fix any potential issues.
- Temporarily disable and then re-enable iCloud Photo Library on both devices.
- Check that the files you're trying to access are in supported formats for macOS Photos.
- If nothing works, consider reaching out to Apple Support for further assistance.
Remember to back up your photos and videos before making any significant changes, just to be safe.
