HI I'm about to buy a laptop for the project (obviously we will be running ROS everyday). There is a Mac culture here. But I have never had a Mac before. If I get one, I will probably install Ubuntu on it to run ROS, since it seems the Mac version of ROS is still not fully running. I don't want to struggle with ROS installation. I am very familiar with Linux but I have never installed it on a Mac, and I know that one of my friends had trouble with that (I think the partitioning phase was the problem). I'd like to get some feedback from the people on that mailing list. Is there anybody here using Mac and ROS (with or without Ubuntu) who could comment? How easy is it to install Ubuntu on a Mac? Once this is done, does everything works fine, especially as far as ROS is concerned? In the past 6 months I was working under Linux 64 bits (on a PC), and not everything was as smooth as the 32 bits version, there were a few tricks here and there... Regards Brice
