[Ifeffit] Demeter on Mac OS X

Hi all, I have used Athena on my Mac since last month, but from last week I have had the below problem to open the software. Could you help me to solve that? perl5.16(423,0x7fff75854310) malloc: *** mach_vm_map(size=18446744071562072064) failed (error code=3) *** error: can't allocate region *** set a breakpoint in malloc_error_break to debug Out of memory! PS: I have 8 GB of physical memory. Cheers, Juliana
