Regarding AMPDeviceDiscoveryAgent filling up system log

MacBook Pro M1 max running 12.5.1


HI, What I've discovered it that AMPDeviceDiscoveryAgent service is related to (in my case) my iPhone. The service starts the first time a phone is connected and then runs looking for a connection. it can be stopped with


pkill SIGSTOP AMPDeviceDiscoveryAgent


However, if at that point you plug you phone in, finder won't see it. Quitting and relaunching Finder will restart the process or use


launchctl start com.apple.AMPDevicesAgent to start it up again.


Perhaps the way it logs will change with Ventura

in the meantime I just stop it with the pkill command so it doesn't unnecessarily fill the system log.


On my MacMini (intel) 12.5.0 it works as one would expect.. The process launches when the phone is connected and stops when the phone is disconnected

MacBook Pro 15″, macOS 10.13

Why the concern over system logs...(?) is there an associated issue


AMPDevicesAgent is the device manager. It is used for backing up, restoring and updating your devices.

This may appear: When you sync your devices over Wi-Fi.



you can file a bug report /submit your Apple Feedback here: Product Feedback - Apple



you make no mention of the exact iPhone or the iOS...

Update your iDevice - The current stable release of iOS including bug fixes, is iOS 15.6.1

Update your iPhone, iPad, or iPod touch - Apple Support

Thank you for your reply


Actually the particular phone is not a contributing factor. Whether my 13 mini on IOS 16.0 or my 12 mini on 15.6.1 the behavior is the same. Like I mentioned before, the service runs as expected on my Mac Mini M1, 2020 on 12.5.1 and my other MacBook pro, 2020, 13" on 12.5.1 but continues to stay active regardless of whether a phone is connected or not on my 14" m1 max.


I'll wait for Ventura to pursue it further.
