Hi Darren -

@darren2

the undo and redo they are greyed out and not working

I just installed Rhino for Mac 5.5.5 and see the same thing on my machine.
I went and searched for previous occurrences of this behavior and only came up with this one:

Rhino Mac UNDO and Command-Z?

Long time PC Rhino user, just opened Rhino for Mac and am lost. How do I UNDO an action? I dragged an object and wanted to move it back, but “UNDO” is shaded out and Command-Z doesn’t do anything. Also, where is the gum ball? I clicked on the Gumball box at the top but no gum ball appears. Thanks !

At that time, no one was able to reproduce that issue and so it must somehow be related to a specific hardware - macOS combination and configuration.

I’m afraid I don’t have anything useful to suggest. The current version is 7.1 and undo is working as it should with that version on that same machine here.

Hi Darren -

@darren2

Yes, that is also on the Mac.

@darren2

where did you buy it

You can find a local reseller from the “Buy” page:

Buy - Rhinoceros

Or, to start with perhaps, download an evaluation version from this page:
