I use KiCAD on both my work PC (Win10 version) and home Mac (macOS Catalina).
One thing I notice is that when I plot the set of Gerbers on Windows, I never see a squawk about the solder mask, but when I go to plot Gerbers from the same PCB file on my Mac, it does squawk about the solder mask clearance not being set to 0 (which I then correct).
Is there a different default value in play between the two platforms? I thought I’d at least call attention to this…
