I have seen two M1 Mac reviews on YouTube today that said Wacom drivers are currently unavailable. This is wrong. The installer is finicky because it throws up a permissions warning but the drivers work fine after you reapply permissions.
Install the driver, ignore the permissions warning after install and reboot.
To reapply permissions go to Security & Privacy in System Preferences.
Click on the Privacy tab.
Scroll down to Accessibility and recheck com.Wacom.IOManager. You can also right click on it, show the driver in the Finder and drag it back into the Accessibility section.
Next go to Input Monitoring and do the same thing with WacomTabletDriver.
The drivers should now work fine and you can edit your settings in the Wacom Tablet preference pane.
