Eyedropper tool 'show sampling ring' grayed out

[hanabostic]

The 'show sampling ring' used to work but now when I press option it does not show and it is grayed out on the tool bar. Photoshop 2020 21.2.1 version on Macbook Pro 2010 (upgraded to SSD and 8GB RAM). I'm wondering if my laptop is too old for the current version. Thank you in advance.

Hi

Check to see if your GPU is been detected in preferences and that OpenCL is enabled

Hi. my  use graphics processor is active and so is the open cL and the eyedropper ring check box is still greyed out. I even tried relaunching photoshop and it's still not working. I'm on the most recent version on photoshop om my M1 macbook pro.
