I am considering buying a service manual for my reference. I like to do simple maintenance i.e. oil changes, brake pads, tire changes etc. The manual is only available on a CD and only operates on Windows. I have a Mac and a small HP Notebook with a small memory. Has any one been able to open this CD on a Mac? Is it a PDF file? It is $140 CDN. I just want to be sure I can use it.
