Hi there 👋
Thanks for posting — and yes, that “Network Error” message is definitely frustrating when you’re just trying to tidy things up quickly.
The Clean Up tool in Apple Photos relies on background AI processing, and in some cases, these features are downloaded on demand from Apple’s servers. Even with a good internet connection, you may still hit temporary availability delays — especially if the servers are busy, the feature is rolling out regionally, or there’s a caching issue.
If it only works after a few hours, it likely means the AI model or its assets didn’t fully load right away. While Apple hasn’t published exact reasons, here are a few things that might help improve reliability:
- Keep your Mac plugged in and idle for a bit. macOS often prioritises downloading heavy on-device AI components when the system is not in active use.
- Disable VPNs or firewalls temporarily that might be interfering with Apple’s background services.
- Check for macOS updates. If you’re on macOS 15.5, you’re up to date for now — but when a point release lands, it might improve Clean Up’s reliability.
- Try using Clean Up on smaller batches of images, rather than launching it across a large group at once.
And yes — the delay is annoying when you need it right now. You’re not imagining it — this tool doesn’t behave like a typical offline Photos feature yet. Hopefully Apple improves how it pre-loads and caches Clean Up in future versions.
Let me know if the issue becomes more frequent or if it disappears with a new update.
