Pd does not launch.
Up to Table of ContentsThis FAQ applies to: Any version.
If Pure Data is not launching on your computer, then check if your /private/etc/hosts file is configured correctly.
You may get the message ERROR: failed to allocate port, exiting! in the console.
The default under OS X looks like this:
##
# Host Database
#
# localhost is used to configure the loopback interface
# when the system is booting. Do not change this entry.
##
127.0.0.1 localhost
255.255.255.255 broadcasthost
::1 localhost
fe80::1%lo0 localhost
if localhost is missing in yours then Pd can't start. It will hang and quit on startup.
