Illustrator 2020 Pressure brush greyed out on MacOS

[ProctorS_Owens1]

Hello,

I am new to using Adobe Illustrator but I have had a immense trouble with the Pressure Brush tool in this application. I have looked up multiple articles and forums to figure it out but with little results. I am not using any sort of tablet or pen assistant tool to use Illustrator, just using my MacBook Air. I am using a MacBook Air 2017, MacOS High Sierra, Version 10.13.6 . I again am not using ANY tablet or pen and tablet combo when using the Illusttrator apllication. I would greatly appreciate any feedback or suggestions on how to rectify this dilemma. Thank you

Sincerely,

Proctor Owens

Without any graphic tablet, you can't have pressure.
