With some tablets, the driver might only appear on the Input Monitoring page, and you may need to reboot a second time for it to appear on the Accessibility page too.
You likely had permissions left over from the previous tablet driver, and these stale entries all need to be removed like so:. Go to the "Input Monitoring page" and do the same there. Now either reboot your computer, or run these two commands in the Terminal, to reload the tablet driver. This should restore the prompts to ask you to add permissions, so now begin the instructions in this section again. For a handful of people, the Wacom driver never appears in the Input Monitoring list for them.
To fix this, first open up the "Terminal" app and paste this line in and press enter to ensure that the Wacom service is enabled:. If that doesn't trigger it to ask you to add Input Monitoring permissions when you try to use the tablet, you can add it manually instead. Now reboot your computer, and when you try to use the tablet it should prompt you to tick it in the Accessibility page too, after which it should start working.
Make sure you don't still have Wacom's very latest driver installed. Corrupt preferences can prevent things from working, especially if you installed a bunch of different driver versions while trying to get things to work.
Use Wacom Utility to reset your preferences, reboot, and try using the tablet again. To find those drivers within its Resources folder it eventually calls this function to extract a path from a URL:. It queues the reference count to be decremented later by calling autorelease on it, then returns it to Wacom's driver.
This call to autorelease pairs up with Wacom's retainAutoreleasedReturnValue call, and so and leaves the path's reference count untouched, at 1. This decrements its reference count to 0, and the path is immediately freed! This kills the driver. This prevents the path from being freed before it is used, which cures the segfault.
Both the pen driver and the touch driver need fixes to stop them from crashing when a multi-touch gesture is performed, or the scroll ring is used to zoom. Notice how the result from CGEventCreate is being cast to a structure? CGEvent is supposed to be an opaque type , programs aren't supposed to know or rely on its layout, since its structure changes from OS version to OS version, but here it is being cast to a structure so that its eventSubType and eventDirAmount fields can be assigned directly.
These two writes cause heap corruption on Catalina and trigger a crash, because the layout of CGEvent has changed since Sierra! So what are the equivalent field IDs for the two writes that the Wacom driver needs to make? But these field IDs are nowhere to be found in Apple's documentation , which explains why Wacom couldn't use them! I did some Googling and discovered that these fields are undocumented because they're part of Apple's private API. This WebKit header reveals their names:.
Now that we know this, the two assignments to eventStructure can be replaced by these calls, and the driver crashes are eliminated:. The Intuos 3 and Cintiq driver has a bug in its preference pane that causes it to crash as soon as an item is clicked on. One of the main features of the preference pane's UI are the lists of icons representing the tablets, tools and applications you can configure. That icon list control uses a function like this to dispatch events such as clicks to its children:.
The problem with this code is that it requires the event's handler function to return an object, which it then uselessly retains and releases. Examine the pen hardware for wear and tear. Perform a power cycle and update the Wacom pen drivers.
Before we put the blame on the Wacom hardware for the issue, first check whether your touch input device is included in the compatibility list. You can check the compatibility list here. Since they are different standards, you will have to manually select the mode from the pen according to your use case. By default out of the box, it will be on Wacom AES mode. If you have been using the Bamboo Ink stylus pen for a long time, chances are the battery has already been discharged to a point it needs replacement.
Also, if the replacement batteries you used are old, chances are that the battery has already eroded enough due to external conditions that it failed to provide a charge. The Wacom Bamboo Ink comes with a set of replacement tips in the box for a reason.
The tips can get easily worn out over constant use. It is a difficult task to notice the wear and tear of the pen nibs as they are already pretty small and little scrapes can only be felt while drawing. Check your pen tips for any visible damage. Change the tips immediately with the proprietary tips provided in the box or sold separately if you notice any deformations.
A power cycle resets the internal components of the Wacom Bamboo Ink by completely discharging all the internal components before powering it on again. This will restart the internal components of the Wacom Bamboo Ink and solve all hardware and power-related issues on the Wacom Bamboo Ink pen.
At times, you might need to manually update your pen drivers on your Windows laptop to be configurable with the latest Windows Ink Protocol updates. This installs the latest windows drivers that are recognized as compatible by Wacom onto your Windows computer. However, if your Wacom Bamboo pen is still not running well, you can always contact the Wacom Technical Support team for more assistance.
