Revision history [back]

Just upgraded, both on iMac with clean install of home-brew + indigo, and on Macbook with existing indigo install, which still appears to work.

However, having some name resolution issues on laptop, which I wasn't having previously. Works fine when I'm on my institution's VPN, but turn wifi off, and roscore can't launch because it can't ping itself. Setting ROS_MASTER_URI, ROS_IP or ROS_HOSTNAME to explicitly point to localhost / 127.0.0.1 doesn't seem to resolve the issue.

Sounds like Apple have been messing around with name resolution, not aware of a fix yet.
