G'day Jerome
I had the same problem as well, the problem is related to not having
enough shared memory. For some reason, Mac OS X sets the defaults
maximum's for shared memory to be relatively low.
The following is a guide on how I managed to get it to work.
Step 1.
Edit Vic file and change
exec mash-5.2.1 "$0" -name vic -- "$@"
To
exec ./mash-5.2.1 "$0" -name vic -- "$@"
or
exec /install_path/mash-5.2.1 "$0" -name vic -- "$@"
Step 2.
Good website
http://developer.postgresql.org/docs/postgres/kernel-resources.html
SHMMAX Maximum size of shared memory segment (bytes)
250 kB + 8.2 kB * shared_buffers + 14.2 kB * max_connections up to
infinity
SHMMIN Minimum size of shared memory segment (bytes)
1
SHMALL Total amount of shared memory available (bytes or pages)
if bytes, same as SHMMAX; if pages, ceil(SHMMAX/PAGE_SIZE)
SHMSEG Maximum number of shared memory segments per process
only 1 segment is needed, but the default is much higher
SHMMNI Maximum number of shared memory segments system-wide
like SHMSEG plus room for other applications
SEMMNI Maximum number of semaphore identifiers (i.e., sets)
at least ceil(max_connections / 16)
SEMMNS Maximum number of semaphores system-wide
ceil(max_connections / 16) * 17 plus room for other applications
SEMMSL Maximum number of semaphores per set
at least 17
SEMMAP Number of entries in semaphore map
see text
SEMVMX Maximum value of semaphore at least
1000 (The default is often 32767, don't change unless asked to.)
The most important shared memory parameter is SHMMAX, the maximum size,
in bytes, of a shared memory segment. If you get an
MacOS X
In OS X 10.2 and earlier, edit the file
/System/Library/StartupItems/SystemTuning/SystemTuning and change the
values in the following commands:
sysctl -w kern.sysv.shmmax
sysctl -w kern.sysv.shmmin
sysctl -w kern.sysv.shmmni
sysctl -w kern.sysv.shmseg
sysctl -w kern.sysv.shmall
In OS X 10.3, these commands have been moved to /etc/rc and must be
edited there.
The default values for 10.3 was
sysctl -w kern.sysv.shmmax=4194304
sysctl -w kern.sysv.shmmin=1
sysctl -w kern.sysv.shmmni=32
sysctl -w kern.sysv.shmseg=8
sysctl -w kern.sysv.shmall=1024
I modified the settings to
sysctl -w kern.sysv.shmmax=34194304
sysctl -w kern.sysv.shmmin=1
sysctl -w kern.sysv.shmmni=32
sysctl -w kern.sysv.shmseg=256
sysctl -w kern.sysv.shmall=34194304
I hope this guide provide some assistance.
Cheers,
Jason.
P.S. I am also very keen to see the AccessGrid Version 2 running on Mac
OS X.

yeah i just recently got the OS X open mash build, the vic as a viewer
seems to work except when i join the lobby and then it quits with too
many files error after trying to load all of the streams
haven't really tried vat much beyond it opening for the lobby
i'm interesting in checking into possibly rebuilding it against OS X
Tcl/Tk if i can get the source with the os x changes.
