Adding a checkmark in Microsoft and MacOS Excel

[Robert_Conklin]

I work from both Microsoft and MacOS platforms. I am in need of a macro that will add a checkmark to a cell easily. I have tried using code from a previous request "Using VBA in EXCEL to add a checkmark to a cell" but it will not work on my new Microsoft machine and I am not sure it will work on my Mac. Thank you in advance for any assistance.
