Layout copy viewports

i just switched from windows to mac and i have some difficulties in layout. I’ve got 2 different layout files and i would like to copy the viewports in one new file, because i’ve allready added a lot of info on top of them.
With my windows computer i could just copy the viewport and then i was able to adjust the scenes, work in the file,… Now on my new mac i do the same thing. Just copy-past a viewport from one file to another, but he makes a screenshot from the viewport view… i can not open scenes or link to a sketchup file…
Can someone help me out?
Thnx !

It would help if you’d share the LO file so we can see your exact setup.

You shouldn’t need to be opening the viewports to “adjust the scenes”.
