Wacom Intuos Pro no pressure sensitivity Photoshop Elements MAC

Hello,
I don't know, how to get pressure sensitivity for my Wacom Intuos Pro with Photoshop Elements  on the mac. As often suggested I have removed the old tablet drivers and now have the newest ones. Unfortunately this did not solve the problem. I'm also using the newest MacOS and the newest version of Photoshop Elements.

The pressure sensitivity works fine, when I use other photo editing software.

Please help me. I'm working now for hours on this problem and can't find a solution.

Thanks!

Markus
