If I update the minimals via first-setup.sh I get the 32bit-binaries (luatex) although I'm on Snow Leopard. If I change the binaries myself it works fine and the compilation is notable faster!
Andreas, Can you please try one thing? In first-setup.sh you can try to add the following lines (around line 56, after the platforms are being recognized): if test "$platform" = "osx-intel"; then # running Snow Leopard or later if test `uname -r|cut -f1 -d"."` -ge 10 ; then # working on 64-bit hardware if test `sysctl -n hw.cpu64bit_capable` = 1; then platform="osx-64" fi fi fi And then update the minimals. After that try to paste the same lines to "setuptex" around line 59, try to run setuptex and try if you get the 64-bit binaries and if they work fine (I can try to do that myself, but I try to avoid rebooting my machine too often). You need to fix setuptex after you update the distribution since updating will change setuptex. If that works for you, I'll fix it. Mojca
