Hi.
I upgraded from Snow Leopard(10.6) yesterday, to Mountain Lion (10.8.3)
Now houdini will not launch. I am getting a large list of continuous errors, that seem to think my Mac is 32 bit architecture.
But its a Core 2 Duo (and also h12.5 and earlier - all worked fine on 10.6

Any ideas ? Id hate to have to revert back…

Heres some of the errors:

The Houdini 12.5.316.22 environment has been initialized.

I'm probably wrong but could the build you downloaded be responsible? I notice there are gcc (10.7) and clang (10.8) builds available.

Thats a horrifying possibility. Thanks. I am actually running the 10.7 build …
so am downloading the 10.8 build now.
However - this means that none of the earlier houdinis will run on 10.8 - disastrous !!
I will check if this fixes the issue, and report back. AND then have to reinstall my mac back to Snow Leopard or 10.7 (lion ?).
Starting to regret using a Mac now …

So installed the 12.5.376 build for 10.8

and rebooted.

Same errors!“/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/lib-dynload/math.so: no appropriate 64-bit architecture (see \”man python\“ for running in 32-bit mode)”

Im now going to take the Mac BACK to 10.5 then to 10.6

any solution to this? was going to upgrade the studio I work at to 10.8 next week, but not if I cant get the artists on 12.5

I've a Mac Pro and Mac mini happily running the latest daily builds and latest os X version 10.8.3

Not sure that the issue is but what model of Mac are you running? There some that can be booted in 32 or 64 bit etc.
