I just spoke to Proving Ground (the devs of Lunchbox) asking if lunchbox will be supported by gh on Rhino8 running on apple silicon.
Unfortunately, Lunchbox requires .NET Framework components which are not natively supported on Apple Silicon. The reason it works on Rhino7 is that this uses Rosetta to run the intel program. Now that Rhino 8 is running natively, Lunchbox doesn’t work.
Proving Ground suggested that I post here seeing if there’s any way to make rosetta work on Rhino plugins running on Rhino 8.
