Damn, here I was getting all excited about Juice FX and Smear FX and no macOS versions at all. What a shame!
I'm running JUICE FX, SMEAR FX (and other small programs like this) on my MAC with CROSSOVER. It puts .exe-data in a virtual bottle and makes it useable from there. Good Luck!by the way: Juice FX and Smear FX ar GREAT Tools!
CrossOver is the ticket! Works great.
