what is com.apple.aneuserd (as opposed to com.apple.aned) & "Group%20Containers" (as opposed to "GroupContainers")

I'm trying to identify folders that may be suspicious.


I can't find any information about a folder ending in .aneuserd within the Library/Cashes folder. (com.apple.aneuserd as opposed to com.apple.aned)


I also am wondering about the "Group%20Containers" (as opposed to "GroupContainers")

(understanding that "Group%20Containers" means "Group Containers" with a space)


OS Sequoia 15.5



MacBook Pro 16″

On macOS, `com.apple.aned` is a legitimate system process tied to Apple Neural Engine (ANE) functionality — often used in ML tasks offloaded from CPU/GPU to the dedicated ANE chip on Apple Silicon Macs. It handles things like Core ML inference behind the scenes.


On the other hand, 'com.apple.aneuserd` doesn't seem to be documented anywhere publicly by Apple or in dev channels, and, AFAIK, it's not found on standard installs That potentially could be a red flag if it appears alongside `com.apple.aned`.


As far as `Group%20Containers` vs. `GroupContainers':`%20` is the URL-encoded form of a space character, so `Group%20Containers` translates to "Group Containers", which is not standard. On a clean macOS install, the path is typically: ~/Library/Group Containers/


If you’re seeing a folder literally named `Group%20Containers`, something suspect is going on — it may be:

  • Created by a script or installer not using proper macOS path handling.
  • A leftover from a poorly written cross-platform app.
  • Or again, possibly malicious or misconfigured software trying to mask itself.
