Sorry No advice. You can't, because Adobe it its shortsightedness hasn't built in XML based PDF support into the Mac Version. And probably never will. Adobe after 20-25 years still considers Macs as toys not really meant for serious work. Despite the fact, were it not for Mac users, And Adobe writing products for Mac first, they would still amount to a Font House today. For two years or more they wrote exclusively for Mac until PC's accepted them, after Mac Users worked the bugs out. Then we were all but abandoned.
We can read XML based PDF's, but can do nothing with them . What we can do, is re-save them which converts them to Plain PDF's. Then go to Forms Manager, and setup the form which will work on all Platforms.
So what you need to do is if you want your audience to include Mac users as well is avoid Lifecycle created forms and don't use any XML Based PDF Form . Create regular PDF forms and will it work on any platform.
