I'm going to try this again, Angela.
I bought Luminar 4 yesterday & it worked well for about three hours before it started to take its time & eventually crashing or just not finishing the job.
When I dowloaded Catalina from Apple I could not get my Luminar 18 to work at all. So, based on what you'd written, I ordered the 4.
So, what's going on, Angela?
