@tigermaster,
…a year later… Did your performance with Logic 9 in 64 bit mode with Mountain Lion improve? Was the 32 Bridge still messy?
I can see you have gone to Logic X, but maybe you still remember?
Due to a very long project I had to stay in Lion for other apps, but just upgraded to ML and any info that you might have in regard to performance improvement would be greatly appreciated.
Thanks!
