Graphics tablet used to work without a third-party driver. How to reenable this? I am using a Gaomon S620 graphics tablet and running macOS Catalina version 10.15.6, although my question doesn't, I think, depend on my specific tablet/OS version.
It used to be the case (before Mojave I think?) that you could plug a graphics tablet into a mac and it would immediately work fine with literally no driver installed. (No fine pressure control or whatever, but I don't need this.) Now I'm guessing that to due some added security restrictions, when I plug in my graphics tablet without downloading Gaomon's driver, my computer recognizes pen movement (the cursor moves), but I am unable to click on anything.
I say that my specific model doesn't matter because many people have had this problem with different tablets:

I know how to solve this issue if I have Gaomon's driver downloaded. Go to Security and Privacy --&gt; Accessibility, etc.
(Basically follow the steps here and give your third-party driver access to your computer.)
But I want to use my graphics tablet without installing a third-party driver. Is there a way to reenable this functionality?
For reference, I am having problems with lag, and I want to check whether it is my driver's fault or if it is just due to high CPU usage. But I can't check because I can't use my graphics tablet anymore without the third-party driver.
Edit: To clarify, I never experience lag (whether the Gaomon third-party driver is installed or not) when just moving the cursor. Lag only occurs when I press down and draw. But as stated above, I can only draw when the third-party driver is installed, as otherwise it doesn't recognize clicks.
First, try adding the software you are using with the Tablet to Accessibility. Next, try to determine what is the default driver used by Catalina for your Tablet, and add that too (if possible) to Accessibility.
While this issue is most probably due to architectural changes in Catalina, try disabling &quot;System Integrity Protection&quot; (SIP) and see if it works:


Go into Recovery Mode by restarting your computer and holding down the Command+R keys until the Apple logo appears on your screen.
Click Utilities -&gt; Terminal.
In the Terminal window, type in csrutil disable and press Enter.
Restart your Mac.


Be sure to enable it again after you are done testing, following the same steps as above but using the command csrutil enable, once you are done testing.
You can use Activity Monitor to detect if high CPU is happening when you are using the Tablet.
(Otherwise, inform the manufacturer of the tablet that you can't test what they are asking you to do because of macOS Catalina. You shouldn't need to jump through hoops for something they should be doing to ensure the product works as described on macOS, i.e. they should be the one testing the products thoroughly for mac.)
