Hi @gari.kun-
How can I be sure Rhino6 is not limited to a certain RAM ? How can I be sure it will use all of my RAM potential ?
There is no sure-fire way that I know of. The best way I know of is to Quit applications and stop background processes. You can use /Applications/Utilities/Activity Monitor.app to see what is loaded and kill those processes that you don’t need.
Rhino for Mac will automatically use your dedicated GPU if you have one. I recommend the gfxCardStatus utility to verify this.
It depends on what you are doing. Some processes are multi-threaded, some are not. In Grasshopper, we now support multi-threaded components. It all depends on what you are doing. You can use Activity Monitor.app how many cores are being used at a time.
I hope that helps,
