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 >

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.

You need to take some other measures in order to sort out the problem.


Mac's do not require third party AV, Protection, Cleaning or VPN to stay safe.

see > macOS - Security - Apple


1) I never heard of the GPG Suite, but it looks like protection ware that has totally invaded your Mac mini.

Uninstall GPG as per the developers instruction and test for a day or two.


2) I never hear of SENA, but it looks like it is some type of audio device paring manager.

Uninstall SENA as per the developers instruction and test for a day or two.

This still sounds like some bad third-party software or the Mac mini attempting to connect to a bluetooth audio device.

Possibly even when the Mac mini is suppose to be in sleep mode.

If the audiomxd numbers seem to be building when the Mac mini is sleeping at night...?

Then as a test, shut down at night and check the audiomxd numbers in the morning after startup.

Maybe something below will help you figure out what process or service is opening ports.


On macOS, ports are opened by specific processes or services that need to communicate over a network. The system uses a process called launchdto manage these processes and open ports as needed. While macOS's firewall helps manage connections, apps and services can still request and be granted access through it. 


Here's a more detailed explanation:


1. Processes Open Ports:

  • When a process needs to listen for incoming connections or send outgoing requests on a specific port, it requests that port from the operating system.
  • If the process is allowed to use the port, launchd (a background service) will open it and keep it open as long as the process is running or actively waiting for connections. 

2. Sharing Services:

  • Sharing services like file sharing can automatically open specific ports to allow other devices on the network to connect.
  • These ports are opened and closed based on whether the sharing service is enabled or disabled. 

3. Firewall:

  • The macOS firewall allows or blocks connections based on applications and services, not individual ports.
  • You can add an app to the firewall's allowed list to grant it access, and macOS will automatically open the necessary ports. 

4. Identifying Open Ports:

  • You can use commands like lsof or nmap in the Terminal to see which ports are currently open and which processes are using them.
  • For example, lsof -i :8080 will list any processes using port 8080. 

5. Closing Ports:

  • You can close a port by stopping the process that's using it.
  • For example, you can use kill -9 <PID> to forcefully stop a process and close its associated ports.

Here's a log of Mac Mini activity from Wednesday afternoon to Thursday evening




2025-05-14 Wednesday


This morning I discovered that the audiomxd CPU Time, Memory, and Ports had continued to grow overnight.


After discovering this, I removed the following migrated items that were found by EtreCheckPro:

Internet Plug-ins:

Flip4Mac WMV Plugin: 3.3.3.1 (? - installed 2015-02-14)

Audio Plug-ins:

Flip4Mac WMA Import: 3.3.3.1 (? - installed 2015-01-05)

3rd Party Preference panels:

A Better Finder Preferences (? - installed 2010-03-21)

Flip4Mac WMV (? - installed 2015-01-05)

MacFUSE (? - installed 2010-09-12)


I looked at processes that were being launched at Startup.


Settings > General > Login Items & Extensions


There was one app that was being opened at Login. I Removed it from "Open at Login."


Next, I looked at "Allow in Background." None of the background apps were from Apple. All were non-Apple, third-party apps.


I had Uninstalled Adobe Creative Cloud, but it was still listed in the "Allow in Background" group.


I switched them all OFF. If this causes trouble, I may selectively switch them ON, but only one at a time.


Why are there three different background apps with the same name "uuid-patcher"?

2025-05-15 Thursday


Yesterday evening, I removed selected Plugins, Preference Panes, and "Open at Login" apps, and switched OFF all the "Allow in Background" apps, then I Logged Out.


Just now, I Logged In and discovered that audiomxd has been: 1) using the CPU most of the time, 2) allocated a little more memory than WindowServer, 3) has opened about three times as many Ports as WindowServer. This may be OK. The question is whether, in the long-term, Memory and Ports remains constant or decreases. Then it would not be a memory leak. Especially, if most of the allocated Memory would be freed and available if the user had need of it.


If audiomxd memory demand continues growing (2, 3, 4 ... GB) and if it is not available to the user, then that would be worth investigating further.

Probably not the cause but should still be gone, delete this file & restart…

Also the high usage started on the day these were installed…

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.

The online Epson Printer Product ET-4850 stalled when I selected macOS 15.x


The Epson Universal driver that I installed on Monday 2025-05-12 had an uninstaller, so I ran it. I selected all the boxes in the Epson software then launched the Uninstaller. After several minutes, a popup declared success, but the Uninstaller popup window continued to remain open. About 15 minutes later I closed it manually.


Next, I went to Apple > System Settings... > Printers & Scanners >

then removed all the Epson printers and scanners. That should have been done before attempting to uninstall the printer driver.


EtreCheckPro was used to remove: com.epson.scannermonitor.plist

Finder was used to remove: /Library/Extensions/EPSONUSBPrintClass.kext

Logged Out. Shut Down. Started Up. Logged In.


Here's the current EtreCheckPro Report.
