I have an Excel application which works fine in Windows (7) and Excel 2010 but perform utterly badly in an Apple Mac with the ordinary office package.
The application consists of a summary sheet with 13000 cells that contains Formulas. In 1/3 of it is simple formula like =RC + RC[-7] or =sum, the rest contains vba customized functions that contains a range call and the range is in another sheet.
In the Windows Environment the updating of the sheet takes a second or two (the Pc is a four core 3,4 GHz with 6 GB). The apple mac (1,7 GHz, number of cores unknown, 4 GB) it takes at least 5 minutes or 300 seconds.
This is an utterly difference, therefore, is there anything that can be done to the apple mac without rewrite the application?
Thanks in advance
