seem like your setting from OS X is ok,did u set static IP or DHCP assigned for your Pi?

the eth0 for rpi is set to dhcp.. i hvae tried to plug it in router, it can get ip form router... no sure why OSX is not working.

At your mac, set the ip of your ethernet interface(lan) to
ip: 10.10.10.11
netmask: 255.255.255.0
Plug your raspi to ur mac and access ur raspi via 10.10.10.10
it that any special by setting to 10.10.10.10?
i have tried to set static on Rpi and OSX before, it worked, can ssh into RPi form OSX, but the problems was: Rpi cannot access internet via wifi any more.
My purpose connecting OSX to Rpi via LAN is for the case whne i cant access the internet ( when i bring it to some place which i do not have the wifi password), i got an other way to connect it, which is LAN for this case.
