Record history: update children

Hi everybody,

I have a problem with RECORD HISTORY: UPDATE CHILDREN.
I am using a RHINOCEROS 6 version for MAC.

I already know, in Mac version, the HISTORY COMMAND is little different.
There isn’t the option to check: RECORD HISTORY: UPDATE CHILDREN but if you check HISTORY BUTTON it should be linked PARENTS/CHILDREN curves/surfaces.

I have tried but it doesn’t work.
Here a screen shot of my trials.

Can you help me. Do you know what I have to check in my HISTORY SETTING?
I can’t find any already done tutorial it can help me.

Thanking in advance!
E.
