Did you upgrade your operating system?

There are instructions on the AIPS Manager FAQ page about the shared 
memory ID failure.  They are
  On the latest "leopard" systems, /etc/rc is gone and creating it will 
have no effect. You need to create an /etc/sysctl.conf file and put the 
values in it,

             kern.sysv.shmmax=10485760
             kern.sysv.shmmin=1
             kern.sysv.shmmni=32
             kern.sysv.shmseg=8
             kern.sysv.shmall=4096

The xdpyinfo | more commands should show 24-bit or 32-bit visuals.  AIPS 
cannot use a 16-bit one but can (sort of) use an 8-bit visual.  That has 
not been tested much of late!  Perhaps our Mac expert can offer 
suggestions on this point.
