The Slide Your Way Through Excel VBA requires Power Point with VBA enabled to run. I have not tried it on a Mac, but I am 75% sure that it would not work. Drop me an e-mail with your address and I will let you beta test a CD for the Mac. If it doesn't work, no harm, if it does, let me know and we can be sure.
There are a lot of difficulties in writing VBA code for the Mac. Much of the basic stuff will work, but if the code uses anything from the Windows API, or DAO, it is going to fail on the Mac. Most of the concepts on the Slide Your Way through Excel VBA CD would work in either platform. However, I would estimate that a bunch (10-15%) of the Holy Macro! CD contain some Windows API code.
