I made the move to All-things-Apple many years ago. I should say almost all Apple as I still use Excel as my spreadsheet software of choice. Im sure that Apples Numbers software is just as good but I know so many Excel hacks that I dread the learning curve Id have to go through to get Numbers to do the same tricks I have Excel doing. Oh well, maybe one day.
You might consider getting (free) LibreOffice for your Mac, since the “Calc” in that is considerably more Excel-compatible than Numbers, according to my spreadsheet-using friends who have one foot in the Mac camp and the other in the Windows camp.
