UARPUpdaterServiceUSBPD process consuming huge amounts of memory

Have the same issue. Reported to Apple through their Feedback Assistant (FB13736647). They tend to respond more promptly when multiple reports are filed. If you're experiencing the same problem, please also report it and reference my feedback ID, FB13736647, to help them consolidate the reports more efficiently. Thanks!

Periodically, the UARPUpdaterServiceUSBPD process will start consuming huge amounts of memory on my system. The amount of memory grows over time, so this appears to be a memory leak. The fans on my MacBook spin up, and the system in general slows down. I have to either forcefully stop the process or restart my MacBook to get the system to get back to normal.

Searching around, this appears to be a widespread problem. See:

• UARPUpdaterServiceUSBPD consuming 4GB of RAM on MacOS

• UARPUpdaterServiceUSBPD memory leak?

Some of my system info:

1.1 GHz Quad-Core Intel Core i5

• 16 GB 3733 MHz LPDDR4X

• macOS Sonoma Version 14.4.1 (23E224)

• No external devices attached, although I do have nearby bluetooth devices. There does not seem to be a pattern of if the bluetooth devices are connected or not.

Is Apple aware of this problem? Are there any fixes coming soon?

Can the user provide a Screen Shot high-lightly offending Process In Activity Monitor

Please use the View >> View ALL Processes

Then, post back using the " Image Insertion "

I can understand that which is in the english script

I am aware that there was a Firmware Updated issued by Apple for specific versions and models of the Apple Bluetooth Keyboard

Which would may qualify as an accessory " accessoryupdater "

Here's one from my 2019 macbook pro:

I'm running:

* Sonoma 14.4.1 (23E224)

* Apple magic keyboard with firmware 2.0.6 (mentioned in an earlier comment)

* This problem was not happening for me last month (before the Sonoma 14.4.1 update)

* Note: force-quitting the process does not appear to free up any memory

I had a long chat about this with Apple support, eventually escalating to phone with their senior support team. Nobody I spoke with had ever heard of this service process, had any clue what it does, what kicks it off, or how to prevent the leak! If I let it run for two or three days it usually grows to about 4GB. I never saw this before Sonoma 14.4.1. I think it is a macOS bug. Fingers crossed that it is silently fixed in Sonoma 14.5.

Today, during a reboot, I connected the charger cable to the right front USBC port on my 2019 Intel MBP 16". Previously I had always connected it to the right rear port. This time, the UARPUpdaterServiceUSBPD daemon appeared briefly at boot and then it (and and all its siblings) disappeared a bit later!

Of course, it could raise its ugly head again later, but so far it has been a few hours and there aren't any of these processes running. I suspect there is a bug in Sonoma 14.4.1's handling of that particular USBC port when it is being used to power the computer.

Please try this if you have

I updated to Sonoma 14.5 and not had any issues so far. The process appears when I connect the power cable, but consumes ~5 MB and terminates after a short time. This seems to be normal behaviour but too soon to say definitively and it was not mentioned in the release notes. Keeping my fingers crossed! 🤞

Further results: After several days with the charger connected on the right front USBC instead of the right rear while running Sonoma 14.4.1, this process would occasionally show up in Activity Monitor, showing about 4MB of RAM usage, then vanish.

After updating to Sonoma 14.5, the behavior using the right front port is the same: shows up initially then goes away without ever growing huge. On the right rear port after 5 hours it is still sitting there at 4.3MB. I'll leave it there overnight to see whether something fires while idle or after a long interval to trigger it.

I conclude that Apple fixed the leak in 14.5, but I don't understand why the two ports yield different results.

This is all on an Intel-based 2019 16" MacBookPro.

Hello, could you check this screenshut?

Thought it is in Chinese you can understahnd what it is, right

hello, same issue here

I am also experiencing this issue. I am using an external bluetooth keyboard and mouse, but not the Magic Keyboard.

Also reported to Apple through their Feedback Assistant (FB13776136)

Same issue, Macbook Pro 2019, 16inch; macOS Sonoma Version 14.4.1

I do not have any bluetooth devices.
