I try to install BSD on an old iMac. All is going fine until the disk partition. As a debian partition already exists, I need to run thru the Partition Editor.There I select Add a partition, the menu shows me the type of partition( freebsd-UFS), its size( the size made available on the hard drive) but I'm unable to either modify its size or enter the mount point(/) or the label: keyboard input is inoperative. I can't go further. Incidentally I came back to a shell promt...and I got a prompt as expected followed by the characters I typed("/", and the label).
