Braytak is absolutely correct. Run a windows emulator on the mac, or you can find someone too re-scale and shift the .pdo files for you, and then perhaps pdf and send them to you.
That is what I have done in the past for Mac users. But it is sometime time consuming depending on parts and usually most don't have the time, or they want to be compensated for it somehow.
My best suggestion for you is run a windows app. So you can use it (Dual OS)
