Macro-Enabled Worksheet created on PC won't open on Apple IOS

I have created a Macro with in a current Excel workbook and saved it as a "Macro-Enabled Worksheet" on a Windows based PC.  However when I go to open it on my Apple iMac but it will not open.  I just recently updated to the High Sierra OS, it was working on the previous OS.  Is there something that needs to be done now to make sure it works again?

 

Thanks for any insight or feedback.
