How To Fix Error Message "Model Unavailable or Corrupt (TF) or (NX)" on Mac

If you receive an error code about missing or corrupted models with (TF) or (NX) in the message on your MacOS device, follow these instructions carefully. Make sure you follow each step and reboot your computer as directed.

If you complete these steps and the error messages still appear, there is a likely permissions conflict between our program and the image used.

Note: If you use Affinity Photo as a host editor and you purchased Affinity from the Apple App Store, the Affinity app will not allow you to interact with our plugins due to Affinity Photo being sandboxed by Apple. The error message in this help article will be the message you receive from our app. Per Serif there is no solution for this other than purchasing and downloading Affinity Photo directly from Serif instead of the App Store.

Instructions

1. Quit out of the Application

2. Open a Finder window

3. Hit CMD + SHIFT + G to open the Go To panel

4. Enter the path ~/Library/Preferences/ into the input field. Make sure you include the ~ at the beginning.

 

You should see a large number of .plist files in that location

5. To find the Preferences file you need, search for the name of the Topaz Labs application you want in the search field. Make sure you are searching the Preferences folder you are currently inside. The preferences file will be named something like this: com.com-topazlabs.TopazDeNoiseAI.plist

6. Once you have found your plist file. CNTRL + Click or right click and select Move to Trash to delete it. You will probably have two .plist files. If after you delete it it is still showing in the Finder window that is okay. If you right -> Get Info you will be able to see the file path and verify that it is in fact in the trash.

7. Empty the trash

8. Restart the machine using Apple Menu -> Restart

9. Rerun the application
