Unknown seams

rorom

Hello, everyone. 
I am baking in Marmoset Toolbag 4 in a MacBook air M1 and in my bake result, I am noticing a seam that shouldn't be existing.
My UVs aren't overlapping, my smoothing groups are ok. One friend made the bake on his computer, I am not sure which is the exact reference but the maps were ok and the seam disappeared. 
Here I show you the seam.

Thank you in advance.

@romrom Check that your padding on that map is exceeding your UV edge border. Do you have your UV edges set to "hard"? It's hard to tell from this image but is this one piece of geometry or multiple? I am seeing a line on the black that is offset from the UV seam you are pointing out. Do you know the system specs of your friends machine that baked fine, was it also an M1 machine?

If it's possible to share those files with us for internal testing then please send them to support@marmoset.co and we will look into this further. Thanks!
