I am running Mountain Lion (10.8.2) on a MacBookPro9,1. I have Serato DJ 1.1.1 and updated to the latest DDJ-SX Firmware ver.1.02. I have MixEm 2.1.0. I followed all these instructions to a tee, even the update about copying the extra files over for 1.1, and I still cannot get MixEm to read Serato DJ for the life of me. Serato DJ will launch under the false name "Scratch LIVE" and loads up fine, but no communication b/t the two. Did the loophole really close with Serato DJ 1.1? THIS. BLOWS.
