Hi,
xcodebuild -downloadPlatform iOS stays at "Preparing to download..."
for the iOS 27.1 Simulator (24A94425). mobileassetd receives 0 bytes.
Environment: MacBook Pro (M3), macOS 26.7.2, Xcode 27
Tried (no change):
- Reinstalled macOS from Recovery
- Safe Mode
- Reset Xcode preferences
- Network to Apple servers is OK
This started in September when the iOS 27.1 beta Simulator install failed (low disk space).
mobileassetd log:
- Failed to set xattr on '/System/Library/AssetsV2/com_apple_MobileAsset_iOSSimulatorRuntime/1d40f…asset' (errno 2)
- SecKeyVerifySignature failed: CSSMERR_CSP_VERIFY_FAILED
- GetDecryptionKey: Failed to obtain decryption key
Is there a supported way to reset the MobileAsset state
or install the runtime manually?

Thank you.
