Spreadsheet for Residential load calcs

[AZsparky]

Does anyone have a link to a current NEC based spreadsheet for doing residential load calcs on a Mac? I need to determine whether an existing 200 amp service in AZ can handle a new 40 amp continuous type load (Tesla Nema 14-50 charger receptacle) Thanks in advance.

Does the excel spreadsheet that mike holt has for free not work on the MAC?
