Wacom driver installation blocked

Hi, I’m trying to install the Wacom driver for my Intuos Pro Large on my iMac running macOS Sequoia 15.6.1

Wacom has tried for hours with me, and directed me now to Apple. They say the system is blocking the installation and it is not their driver.

I followed all official clean install instructions, including:

Deleting old Wacom files and receipts

Running spctl kext-consent add G8446T3C9N and spctl --master-disable in Recovery Mode

Reinstalling the latest driver (version 6.4.10-3) from the official site

But after installation:

I get these messages non-stop, and they are in a loop

I get no “Allow” prompt in Privacy & Security

In Accessibility these are added

In Input Monitoring I have these

But the Wacom customer service says that this file is missing to be connected here: WacomTouchDriver, Com.Wacom or WacomIO_Manager

Can anyone help me with this issue?

Thank you

Corinne
