When you have pen pressure in all your drawing software except in Adobe Illustrator, please follow the steps from this article: How to Setup Pen Pressure on Adobe Illustrator.
If, however, you've set your brush with pen pressure, but it still doesn't work, please proceed to the steps below:
Method 1
- Step 1. Open "System Preferences".
- Step 2. Find Security & Privacy –> Privacy –> Automation.
- Step 3. Press the "Command" and "Space" bar on your keyboard and type "Terminal" to open the Terminal window.
- Step 4. Input this command in the Terminal window: "tccutil reset All com.adobe.illustrator" and run (hit Enter on your keyboard). (It will show you have successfully reset the program)
- Step 5. Restart Adobe Illustrator, and on the pop-up window, press "OK". Restart Adobe Illustrator again.
- Step 5. Create a new calligraphic brush that supports pen pressure.
- Step 6. The setup is successful.
Method 2
- Step 1. Open "System Preferences".
- Step 2. Find Security & Privacy –> Privacy –> Automation –> Ensure that the "TabletDriver" is checked under Adobe Illustrator
- Step 3. Click on "Input Monitoring" and make sure that the HuionTabletDriver is checked. If it is greyed out, click the lock at the bottom left corner to make changes. Remember to lock it again after the HuionTabletDriver app is checked.
Method 3
- Close Adobe Illustrator and reopen it.
- While reopening it, hold SHIFT ALT and CMD.
- When asked if you want to reset your settings or preferences, choose "Yes". All your settings and preferences will be reset to default.
NOTE: Not all brushes have pen pressure. It is recommended to use calligraphic brushes that support pen pressure.
