The question in this thread was about a MacOS application or plugin. There are tons of windows applications and plugins - even loads of good ones. Yes - but the same thing as with xNormal.
I’m using 12 pixels at 8k because the majority of the texture is a similar material using similar paint. Pad the texture by 8 to 16 pixels, depending on the map resolution.
Resize the texture to half-res and select Filter → xNormal → Dilation.
