audiomxd high memory allocation port allocation CPU time

Apple Community.


audiomxd Memory and CPU screenshots


In February 2025, I bought a Mac Mini then migrated from my iMac (Retina 5K, 27-inch, Late 2015) to my current Mac Mini M4 Pro. The Mac Mini is probably running Rosetta.


About: Mac Mini 2024 M4 Pro. 64 GB Memory. macOS Sequoia 15.4.1. Apple Pro Display XDR with NO MICROPHONE and NO SPEAKER. No Audio app. No VST plugins.


The Apple Pro Display XDR is connected with an Apple Thunderbolt 5 cable to one of the three Thunderbolt 5 ports in back.


An external Lacie backup drive is connected with an Apple Thunderbolt 4 cable to one of the three Thunderbolt 5 ports in back. Time Machine backs up the Mac Mini M4 Pro once a week.


Feedback - Mac mini - Apple

Feedback report 6 on the audiomdx memory leak.

2025-04-26 12.23PM 1.36 GB 102,386 Ports.

2025-04-27 10.14AM 1.52 GB 130,067 Ports.


On 2025.04.27 I changed some settings then Shut Down.

Apple > System Settings > Apple Intelligence and Siri >

Apple Intelligence: OFF

Siri: OFF

Adobe Elements 2021 Organizer > Preferences > Media-Analysis >

Generate Auto Creations: OFF.


On 2025.04.29 I uninstalled an Adobe desktop app the Shut Down.

On 2025.05.03 here are Activity Monitor screenshots of CPU Time and of Memory Allocation.


2025.05.03 12:49 PM audiomxd CPU Time 20:02:08.10


2025.05.03 12:49 PM audiomxd Memory 770.2 MB 39,904 Ports.


Usually, I Logout after each time I use the Mac Mini.

Occasionally, I only Lock the Screen.


Why is Memory allocated, but not freed after closing the app that was using the Memory?


Why does audiomxd need an ever-increasing Memory Allocation to manage the internal speaker on a Mac Mini? I have no external speaker or microphone.

Thank you, den.thed, for the excellent descriptions. Given the growing amount of memory allocated and of the growing number of ports opened, it appears that processes or services or apps are CHECKING IN, but they are NOT CHECKING OUT.


Previous reports from EtreCheckPro mentioned the following kernel extension:


Kernel Extensions:

/Applications/Toolkit.app

[Not Loaded] SeagateDiskService.kext - com.seagate.IOSED01 (67.0 - SDK 10.10)


I just now removed it and rebooted.

The number of open Ports hasn't changed much, but audiomxd continued running overnight and allocated additional memory.


The Mac mini's current Wi-Fi network isn't shared with AirPlay devices. It's also NOT shared with the AirPrint printer, and the Mac mini will eventually need to be connected to the previous Wi-Fi network, which IS connected to the AirPrint printer.


Yesterday, I deleted several old system files associated with old apps. My old iMac used macOS Monterey, which ran old apps written in Complex Instruction Set Computer (CISC) language. The new Mac mini M4 Pro uses macOS Sequoia, which runs new apps written in Reduced Instruction Set Computer (RISC) language.


A new app written in RISC language is like a thought-for-thought translation from CISC language. Using a binary translator such as Rosetta is more like using a word-for-word translation from CISC to RISC.

So it looks like the audiomxd CPU usage has subsided, but the creation of new ports is still off the chart.


A Google AI response says:

In macOS, various processes can create and utilize ports. While launchd is responsible for managing many system services and their associated ports, individual applications can also open ports for communication. To identify the specific process using a port, the lsof -i :<port_number> command is useful. This command lists open files and network connections, allowing you to see which process is associated with a particular port. 


for more info, see > what macOS process is creating ports


Personally I think that I would just uncheck Ports on the Activity Monitor toolbar and go on with life.

macOS Sequoia is unfamiliar.


Here are three screenshots of Activity Monitor processes related to audiomxd. The other View options returned no process.

My iPhone may be connected to this Mac mini via the iCloud, because if I delete an iPhone Reminder, then it is deleted on the Mac mini, too.
