I can see that causing a delay on a system like yours which would only be able to utilize the CPU. Raytraced uses a lot of system resources and was not available in Rhino 5 as you know. Please indicate the exact steps such as if you are pasting to/from Rhino 5 or Rhino 6 and what objects are being selected. I’ll need to reproduce that here for a bug report. If you can post any small file that takes longer to copy and paste from Rhino 6 than it did from Rhino 5, please do so. If you do use Rendered mode in any of them, make sure the settings are the same as those in Rhino 5 for a better comparison. My only other suggestions regarding what is slow still without trying to run an external monitor, would be to check that the named views are not using Raytraced or Rendered modes as those will take more system resources. that having you test 6.17 when you can is the best way to see if things have improved on a Mac like yours. For general veiwport perfomance, make sure that the display mode settings in Rhino 6 match what is being used in Rhino 5 as that version couldn’t do the same things in the display.
