High Pass Sharpen Not Working on Mac OS10.14.6

[jedorme]

I am unable to use this sharpening tool either as a regular Filter or Live Filter Layer on my iMac running Mojave OS.  All other sharpening filters (Unsharp Mask & Clarity) work as Regular or Live Filter Layer on my iMac.  I only get a greyed out screen, but if I push the Radius slider all the way to the right, a very faint, greyed out image appears.  In both methods of attempting to use this filter in the Photo Persona, I first created a new consolidated image layer also.  Is this a known bug?

Hi jedorme,
You need to set the High Pass filter’s blend mode to Overlay to hide it’s grey colour.

Pls disregard this erroneous bug report as further research into using this filter educated me to understand this greyed out screen was normal & that the blending modes in the Overlay block were needed to see its effect.  Now I understand why I had never used this sharpening tool beforehand.  Think I will stick with Unsharp Mask & Clarity.

Thanks as I think you were offering this advise as I was discovering it as well.
