So I finally made the switch from being a lifelong PC guy to buying a Macbook Pro.
Today we shot some Red tests so I now have some footage to play with.
The problem is I can't get any of the proxies to play. The R3D's work fine in RedAlert and Redcine.
I have already downgraded to Quicktime 7.3.1 using the instructions someone thoughtfully posted here.
When I first opened an _F proxy today Quicktime took me to a codec download page, but didn't tell me which one to download.
All 4 of the proxies simply show a white screen when I play them.
Footage was shot with Build 15 v2.1.4
Everything else seems to work fine in Quicktime, just not the camera proxies.
Thanks for your help.
