I have just upgraded to a new 16" Intel MacBook Pro running Big Sur and at the same time upgraded to Rhino 7. MacBook Pro (16-inch, 2019), 2.6 GHz 6-Core Intel Core i7, 32 GB 2667 MHz DDR4, AMD Radeon Pro 5600M 8 GB.
Two-finger trackpad view navigation (rotate view) regularly freezes for a few seconds. Pinch zoom works fine even when tow-finger navigation when frozen. The interruption to workflow became intolerable and I was forced to revert to Rhino V6 where the problem does not occur.
