As far as I know, you can only install if you use the nopgt kernel
parameter or change the partitions after the install. I could of
course be wrong, but nothing I found contradicted these facts.

On my own iMac, when I tried to do preupgrade from the working F15 to
F16 the system would not boot into F16. I the tried to install the
live CD and I could not get that to boot either. I tried both using
reFit and using the whole disk.

Has anyone managed to install F16 on a Mac without using any extra
options such as nopgt or changing partion flags after install?
