Summary: This post from iBoysoft aims to explore the TGOnDeviceInferenceProviderService.appex and fix the issue of TGOnDeviceInferenceProviderService.appex hogging almost all CPU on Mac. If you run into the same process, click in to read!
While troubleshooting some other issue with Activity Monitor, this process "TGOnDeviceInferenceProviderService.appex" appeared at the top of the %CPU column. An internet search did not produce any clues as to what this process is. Is anyone familiar with it?
Like the issue above, you may not be the only one who runs into a strange process called TGOnDeviceInferenceProviderService.appex or TGOnDeviceInferenceProviderService which runs out of almost all the CPU on a Mac. In fact, loads of users have complained about experiencing such an issue online.
Take it easy. This post walks you through the definition of the TGOnDeviceInferenceProviderService.appex process and explores how to release the CPU column occupied by it with professional workarounds. Let's get started then!
TGOnDeviceInferenceProviderService.appex on Mac: definition
You may be new to this strange and long-winded TGOnDeviceInferenceProviderService.appex process, but you must have heard of Apple Intelligence, a personal intelligence system integrated deeply into Apple products that has been introduced thoroughly on macOS Sequoia 15, iPadOS 18, and iOS 18.
The TGOnDeviceInferenceProviderService.appex, also appearing as TGOnDeviceInferenceProviderService, is a process that implies the Apple Intelligence is running in the background on the Mac for offering you relevant service at any time.
When the Apple Intelligence feature works on applications like Mail, Messages, Siri, and Photos quietly, or gets ready for performing tasks like recording video and audio without notifying you, the TGOnDeviceInferenceProviderService.appex issue then shows up in the troublesome way of hogging a large amount of CPU and makes itself top in the CPU column.
This TGOnDeviceInferenceProviderService.appex process takes up nearly 100% of CPU, heating your machine, spinning the Mac fan, making noise, and lagging the Mac performance to some extent. To get your Mac workstation work normally, you'd better release the CPU occupied by TGOnDeviceInferenceProviderService.

How to fix TGOnDeviceInferenceProviderService on Mac?
The TGOnDeviceInferenceProviderService process eats up the CPU column wildly due to the Apple Intelligence's continuous work on the operating system level.
To stop this situation, here are two approaches you can take into consideration: one is to kill the TGOnDeviceInferenceProviderService in Activity Monitor, and the other one is to turn off the Apple Intelligence feature manually.
Approach 1: Kill TGOnDeviceInferenceProviderService in Activity Monitor
This way suits the people who enable the Apple Intelligence feature to perform specialized tasks on a Mac workstation, which temporarily kills the TGOnDeviceInferenceProviderService process in Activity Monitor to free up the CPU manually.
- Open Activity Monitor via Spotlight Search shortcuts or Finder > Go > Applications > Utilities > Activity Monitor.
- Go to the CPU section and locate the TGOnDeviceInferenceProviderService process in the list, which will be easy since it always tops in the process list.
- Select the TGOnDeviceInferenceProviderService process and click the X button in the top menu bar of Activity Monitor.
- Then the TGOnDeviceInferenceProviderService is quit from running, you can check if the CPU usage drops to a normal condition.
You can also select the TGOnDeviceInferenceProviderService in Activity Monitor and click the i button to explore its parent process and process group, then analyze the culprit process or application for a deep resolution.
Approach 2: Turn off the Apple Intelligence on your Mac
If you have no interest in experiencing the considerate AI service provided by this highly-hyped feature, you can turn it off to prevent TGOnDeviceInferenceProviderService from swallowing up the CPU and leaving no room for other programs or processes to run in further performance.
Here is how to disable the Apple Intelligence on your Mac:
- Click the Apple Menu on the top left corner of the Mac desktop.
- Select System Settings from the dropdown menu, then click Apple Intelligence & Siri.
- Click the button next to Apple Intelligence to disable it.
Once the Apple Intelligence function is turned off, the TGOnDeviceInferenceProviderService will not burn the CPU part any longer.
Final words
Every new feature brings new functions and troubles simultaneously. Apple Intelligence can perform sorts of tasks on Mac like writing and refining text, creating images, taking in-app actions to simplify interactions across apps, and it helps Mac users a lot for sure.
However, the TGOnDeviceInferenceProviderService process related to Apple Intelligence runs out of CPU, preventing the Mac from normal working, which is an awful experience. If you meet such an issue also, try to shut it down in Activity Monitor or disable the Apple Intelligence.
