I want to open a powerpoint presentation (not made on a mac) on my macbook. how would I do that? can I download powerpoint? would it work on a mac?
It will work on a mac, I open / use powerpoint on my mac all the time. There is an equivelent in the Mac "office" like software called Keynote (part of iwork, if you have that).
ues Keynote OR get a windows emulator like WINE and use that
