A process named Mobileassetupdaterd owned by the user _accessoryupc, hogs 35% of CPU. It's associated with a file named MobileAssetUpdater at: /System/Library/PrivateFrameworks/MobileAssetUpdater.framework/MobileAssetUpdater Which is a 35 byte alias pointing to the executable at: /System/Library/PrivateFrameworks/MobileAccessoryUpdater.framework/Support/accessoryupdaterd Which is consistently relaunches using this Plist: /System/Library/LaunchDaemons/com.apple.accessoryupdaterd.plist I tried unloading the process with this command others have suggested: sudo launchctl unload -w /System/Library/LaunchDaemons/com.apple.accessoryupdaterd.plist But I just get the error: Unload failed: 5: Input/output error So I'm just not a Terminal master. I've also tried exhaustive searches at Apple, here at StackOverflow, and online to find a solution, with no luck. I watch processes periodically, and it wasn't there until I Updated OS from Ventura to Sonoma 14.5. Anyone have thoughts? Running macOS Sonoma 14.5 on 2021 M1 MacBook Pro. Thanks!

  • Thanks for the kind reply. I've tried everything. Can't unload it with terminal because of system integrity protection. Apple help just want's me to reinstall OS but warned that the Time Machine backup might still contain the problem. That's because…
