Wacom's macOS drivers for Bamboo, Graphire, Intuos 1, 2 & 3 and Cintiq 1st gen tablets have bugs in them that cause them to completely fail to start on macOS 10.15 Catalina and later versions (including 11 Big Sur and 12 Monterey). 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. 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. 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 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.

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 tried to re-install the Wacom Drivers for the tablet to troubleshoot whether this was a hardware (mouse itself) or software (drivers) problem. I noticed my Wacom Intuos 3 mouse was acting strange (clicks not always being registered). I have an old Wacom Intuos 3 tablet (with pen and mouse) that I occasionally use with my Mac (OS 10.12.6 - Sierra).
