I am no expert with networking either, for a more complete description use wikipedia or just google and read.
Here is what I think i understand is happening here. OSX is setting up the network so only 3 IP addresses on this network can be used, *.1, *.2, and broadcast *.255. broadcast is never assigned to any one machine. Now, the BBB is set to have the whole range open. That is *.1-*.254 plus *.255 for broadcast. I believe this can cause network issues, so best to have both set to the same value. the OSX value of 255.255.255.252 is possibly slightly more secure. BUt if the OSX machine and the BBB are connected directly together . . . personally I think it is a moot point. SO, change either the BBB to 255.255.255.252, or the OSX machine to 255.255.255.0.
