Containers in Rhino 8 for mac

Hi All,
Not using Mac, I couldn’t test it.
I ask: having created a command container in Rhino8 for Win and exported it in the .rhc format, is it possible to transfer it to a version of Rhino 8 for Mac?
and if so, what is the procedure?

I’m also going to join in for this Question.
I was working on a Windows Version of Rhino 8 for work and now want to transfer my custom Popup Toolbar to my personal Mac Version RH8. Is there a way? From what I’ve read, rhino does not natively support switching between platforms in a convenient way…
