Have you tried with 4.3.x for instance (not Apple build)? There should be also 4.4.x
available.
Anyway, if you really want to do big calculations on a Mac with Intel CPU, I strongly
suggest to use ifort/icc (for simple tests on pw.x I found that the speed-up can be huge).
It is not free for Mac, but you can buy student/academic licenses (I bought a student
suite for 40 euros, with ifort, icc, mkl, idb, ipp, ... all included).
