Crash when reorganizing tool bars

You have changed Rhino 7 panels and tool bars system and you have destroyed Rhino only because Rhino 8 must be identical to the MacOs version.
First, Apple will not have anymore decent 3d workstations. My latest (and least!) workstation is a Mac Pro, but I always have use it in BootCamp because the many pci slots, 1.5TB of maximum memory and four TB3 ports. Two years ago there was nothing similiar in the workstations market. I have 3 graphic boards installed inside my Mac Pro 7.1 and one external. Unfortunately the latest Mac Minis and Studios are only all-in-one computer toys to model very simple projects. Do you want to render a big project using Cycles or Vray using the RTX kernel? You can’t! Metal is not a professional framework for 3d apps, it’s ok for Apple TV games.
You do insist to develop a 3d app for an hw which will never be professional. The thing is we will not see a new Mac Pro ad WWDC.
Professional “enterprise” level 3d modeling app live only in the Windows domain. See Nx, Catia, Solidworks, Ansys and more.
I love the Apple ecosystem but for 3d we need bad, heavy, power hungry and raw electronics.
