Hi,
I'm experiencing a strange issue with iCloud Drive and Xcode on a Mac mini (Apple Silicon).
Environment
- Mac mini (Apple Silicon)
- macOS Tahoe 26.5.2
- Xcode 26.5
Symptoms
- Files in iCloud Drive Desktop stay at "Waiting to Update" for several days.
- Cloud icons never disappear.
- Moving projects from iCloud Drive Desktop to ~/Developer takes hours or never finishes.
- Existing Xcode projects stored in iCloud Drive open as a white "Loading..." screen forever.
- New Xcode projects work normally.
- Projects already moved to ~/Developer (for example one project) open and build normally.
What I have already tried
- Restart Mac
- Updated to the latest macOS
- Cleared Xcode caches (DerivedData, Archives, old simulators)
- 132 GB free disk space
- killall fileproviderd
- killall bird
- brctl download
- brctl diagnose
- fileproviderctl check -P
Logs After restarting fileproviderd, I continuously get messages like:
Possible slow statement on SELECT ...
scheduler not stable: jobs are running
fetch-metadata ... is busy
fileproviderd constantly uses around 70% CPU.
Also, fileproviderctl check -P never completes. It stops at:
"About to launch FPCK checks for 1 domains"
and stays there for more than 10 minutes.
Questions
- Has anyone experienced this with macOS Tahoe?
- Is this likely a CloudDocs/FileProvider database issue?
- Is there any safe way to repair the FileProvider database without risking iCloud data?
- Is there any way to identify or clear the stuck synchronization queue?
Any advice would be greatly appreciated.
