Intuos 3 Drivers for Mac OSX Sierra (10.12)

I have an old Wacom Intuos 3 tablet (with pen and mouse) that I occasionally use with my Mac (OS 10.12.6 - Sierra). I noticed my Wacom Intuos 3 mouse was acting strange (clicks not always being registered). I tried to re-install the Wacom Drivers for the tablet to troubleshoot whether this was a hardware (mouse itself) or software (drivers) problem. When I reinstalled the latest drivers that work with Intuos 3 tablets for Mac (**Driver 6.3.15-3**), the Wacom Preferences Pane kept saying there was something wrong with the driver and the computer needed to be restarted, and if the issue persisted to re-install the driver. I restarted my computer a few times and still had the issue, then I un-installed and I re-installed the driver and still had the issue. I realized it was probably because the supported Mac OS versions were 10.8 - 10.11 according to the Wacom Driver site and searching "Intuos 3" . I was running Mac OS 10.12.6. I then tried installing the most recent drivers (**Driver 6.3.37-3 for macOS 10.11 - 10.15**) because I thought that might work with my newer Mac OS, and after installation the Wacom Preferences Pane kept saying there were no devices attached, even when my tablet was plugged in. **How do I get drivers for Intuos 3 that work with Mac OS 10.12?** It used to work just fine, but now with no working drivers, my tablet is not mapped to my screen properly and using my mouse/pen is terrible.
