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!

    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.
