Is there a package for Win?

Yes. I can confirm. I am using Rhino 8 on Mac M3 Max with Sonoma 14.4.1 and Opennest 1.5.1.
Just open Rhino8 with Rosetta, than attach in grasshopper your Geometries and Sheets with Opennest. You will receive error message, that Apple can’t open “libsimpleDYLIB.dylibb” because of security reasons. Just click OK. Then open manually the “libsimpleDYLIB.dylibb” File with the Terminal and Apple will add this file to the “secure” files / whitelist. Now just run again Grasshopper with Opennest and it will work.
It does, just download the current version and place it in Grasshopper Libraries folder. Rhino 8 has not changed of C++ architecture as Rhino 7 and 6:
To make it more fluent I can change the package manager naming, but it does work…
I tested Package Manager on Rhino8 both windows and Mac, seems to install without problems.
Is there any way to to get this to work in Rhino 8 for Mac without reverting to Rosetta? No worries if not.
What Mac version you are using?
I ll try on my old Apple M1, and let you know.
Im using Sonoma 14.4.1 (23E224)
This took me some time to update but it is finally here.
I updated OpenNest to work with rhino8 NET core 7 on arm64 and windows 11.
Interface changed of OpenNest, because I optimised a few features. Now you need two additional components for sheets and geometry. This is to simplify sheet making process as well as nesting polygons with attributes. Example files are in the Food4Rhino repository. You would need Rhino 8.7 at least.

Thank you for updating the plugin. But i am missing the PCA component, which i used to get the planes/orientation of planar surfaces. Has it been replaced by Hull? Unfortunately i cannot get the same result with this component. First of all i lose the data structure after output from P0. Unflattening also doesn’t seem to work, as also the outputted planes differ from the expected result. Possibly needs some fixes? In the meantime i would be helped if it is possible to get the old PCA component. It was working in R8.
I uninstalled v2.0 and tried installing v1.51 but it seems to automatically update to the latest version. Is there a way to prevent this?
I managed to get the old version working parallel to the new version by just dropping the files in the components folder, so i have the PCA component working again. I noticed however here is also the Hull component, so the PCA component was discontinued? How come?
I will bring it back 
Did not throught that anyone is using it.

Great:) Its my go-to to find orientation of surfaces. Has also been helpful to pre-rotate shapes for nesting. But maybe others use Hull for this. Anyway thanks!
Hi, is there a way to run simulation in real time (iterative mode) like there was in 1.5.1 when setting iterations to 0 and then setting boolean to run it? I don’t see option for that anymore.

At the moment no. Was it honestly useful?

hi in this new version open Nest for numbers or other geometry transform is not Correct
Transform.gh (32.3 KB)
maybe must add Transform to
nest _Geo Components– I solved this problem by finding the index, but converting the conversion is faster…
open nest nimbers.gh (25.5 KB)

It seems only indices are wrong? Is it true?
I will correct this, and add to the nest geo attributes input, to avoid transformations.
