Test if it is a Mac or a Windows Machine

More information about testing the Excel version or Excel language you can find on this page :
Mac Excel version and Mac Office language settings

We use the conditional compiler constants to test the Operating system or test if you run a 32 or 64 bit version of Office. The macro below will test the Operating system, you can replace the msgbox line with your code or Macro call to run the code you want.

Office 2011 for the Mac is always 32-bit and Office 2016 for the Mac can be 32 or 64-bit, all builds 15.26 and later are exclusively 64-bit. So, every Mac Office 2016 install that is up to date and every Excel version that is higher are always 64-bit

Below you can find a test macro and three UDF functions that you can use to test the Operating system, test if you run a 32 or 64 bit version of Office and give you the Excel version number.
