The lower message tab doesn't show messages anymore

Can someone please help me, I have lost the use of the lower message tab on grasshopper 7 for MAC and I don’t know how to restore it, so when I save the file, no message of confirmation appears in the lower tab.

Hi Nicholas -

Thanks for reporting that! I’ve put it on the list as RH-68957.

RH-68957 is fixed in Rhino 7 Service Release 20
