AmpDevicesAgent?

I think from context it's iTunes agents. There's also an AMPArtworkAgent and AMPLibraryAgent to support that theory.

AMP = Apple Music Player

AMPDevices = Apple Music Player Devices (aka iPhone, iPad, iPod)

Apple seems to be going down a route to rebranding iTunes as Apple Music, so the name change makes sense.

That would be very interesting considering it's part of MacOS Catalina with a clean install.

Apple support usually has no idea about this kind of technical information.

I doubt Apple itself want to scam and steal your info, they could do that without asking for the password...

It is definitely a sync agent for finder that replaced iTunes. If it works as intended you can sync and backup your phone. But it can get stuck and use a lot of CPU in the background.

The password is probably needed for the encrypted iOS backups.

It appears when your phone connects to your mac... The same thing just appeared for me when I connected mine with the lightning charging cable. No need to worry, either let it do its thing or disconnect your phone from your mac and continue on with your day!

For what it is worth, I found this online when searching (you may have to scroll down to Problem 13): https://www.tenorshare.com/mac-os/macos-catalina-problems-and-fixes.html#p13

I don't know the veracity of that information, but it seems trustworthy. It indicates that this is a part of the iOS framework... ie. Apple.

Now, why Apple would surface this request with such user-unfriendly technical jargon that makes it seem like it is potentially a third party request is just bad user experience design because it injects doubt and questions of trustworthiness into the process without any clear way to validate the request or the source. Tsk tsk tsk.

Anyway, hope that helps!

You don't need the keychain password; it's asking for your Mac admin password (whatever password you use to unlock the screen). I read the description od what the options, pressed deny, and the iPhone X (old, I know, but so am I) started backing up to the computer. I agree with other comments, it appears to be an artifact of Catalina.

Until an authoritative source at Apple tells me otherwise, I'll continue to hit "DENY."

You can kill this in activity monitor, there is a force close option.

Direct from Apple... No, it is not Malware, a virus, or trojan.

I get the message on my iMac when syncing my iPhone 11 Pro. The AmpDevicesAgent wants access to my keychain. I do not allow as I don't know what this is.

Not sure what looking in the directory does for me.

Can't see why Apple would have some nondescript App ask for access to my keychain.

What is this? It smells fishy, as it appeared all of a sudden.

My current issue is that it is using up a lot of CPU and my fan keeps running! Over 90% up to 100%

The specific hostname it points to is updates-http.cdn-apple.com and appears to be a download for the new iOS. were you happen to be updating your phone at the time?

What it wants is the password which you use to access your Mac, the one you use when you boot your computer.

It is part of macOS. Apparently it's the new device manager (it resided inside of iTunes before). It is used, for example, for backing up, updating or restoring an iPod, iPhone or other device connected to your Mac.

It resides here:

/System/Library/PrivateFrameworks/AMPDevices.framework/

If you want to pay a visit to that folder, you'll even find device icons.

/System/Library/PrivateFrameworks/AMPDevices.framework/Versions/A/Resources/iPod1.icns

Also, if you want to check, try to put your iPhone in recovery mode and plug it to your Mac. Then, open Activity Monitor to track its activity go up.

Cheers!

I think it has to do something with the removal of iTunes and the features moved into finder.

I am having issues with this because i keeps my mac awake forever and its running hot.

Activity monitor shows 99% CPU usage .

Cant figure out how to disable it.
