So as I now and then have to fix up a OS X + FCP install with XDCAM PDW-U01 import functionality, here is a short howto:
1) PDZK-P1 XDCAM Transfer, now 2.12
2) Mac i.Link FAM driver
3) XDCAM Browser, currently 1.2
The links might break, so here is the official Sony XDCAM site.
I am not affiliated with Sony, nor do they pay me for this. It’s just a braindump for myself and hopefully others will find this helpful!
