iCloud & iCloud Photos · Troubleshooting iCloud space
What do I do when my Mac doesn't have enough space to download an iCloud file?
Short answer: Free space first — an online-only file needs room to download. Tap Run Tuhi, move big apps or non-synced folders to your external drive, or check What's Using Space, then open the iCloud file again.
Free some space on your Mac first, then open the file again. An online-only file needs room on your disk to download, so a nearly full Mac can't open it.
Quick ways to make room with Storage Studio:
- Tap Run Tuhi for the one-tap safe routine — it clears rebuildable caches, reclaims old local snapshots, and frees other large downloaded cloud files.
- Move big apps or non-synced folders to your fast external drive (they keep working through a shortcut).
- Check What's Using Space for the biggest items.
Then try the download again. If space is very tight, Storage Studio's emergency space options help you get back above the danger line first. See freeing space.
