The core dump I gave you is from the 10.8.4 machine. The other has 10.6.8. Both machines have Intel Core 2 Duo chips (dual core, 64-bit) with 4gbs ram and are Macbook Pros, best I can tell both are from the pre-unibody 2008/2009 time period and have near identical hardware (I got them used so I don't know their exact age). These days I use them mostly as "lowest common denominator" test machines. Not sure what other more specific hardware info you need - let me know. FYI, for Director 12 projectors the minimum OS requirement is 10.6. But I am more concerned that a machine that is capable of running the latest Mac OS can't run fluidxtra. I had sent you the cpu capability list from the 10.8 machine earlier, here is the same list again but from both machines:10.8.4 Mac:marcel-winmacbk:~ marcelblum$ sysctl hw.optional
hw.optional.floatingpoint: 1
hw.optional.mmx: 1
hw.optional.sse: 1
hw.optional.sse2: 1
hw.optional.sse3: 1
hw.optional.supplementalsse3: 1
hw.optional.sse4_1: 1
hw.optional.sse4_2: 0
hw.optional.x86_64: 1
hw.optional.aes: 0
hw.optional.avx1_0: 0
hw.optional.rdrand: 0
hw.optional.f16c: 0
hw.optional.enfstrg: 0
10.6.8 Mac:new-host:~ marcelblum$ sysctl hw.optional
hw.optional.floatingpoint: 1
hw.optional.mmx: 1
hw.optional.sse: 1
hw.optional.sse2: 1
hw.optional.sse3: 1
hw.optional.supplementalsse3: 1
hw.optional.sse4_1: 1
hw.optional.sse4_2: 0
hw.optional.x86_64: 1
hw.optional.aes: 0
So basically identical processors, I think just 10.8 shows more possible options that the cpu doesn't have.
