[Miro Le Ravi]

hello everybody
some of you have be very kind when i had  my troubles  installing  my dp  after a trash disk on my old g4
eveything is back again 

i thanks  die hard ,mac torn  and a lot of you  guys  mr happy etc etc .. 
happy year 2017
 
i have  probably not seen this topic about it
but we have tried  to connect with an ethernet cable  ( double crossed)   
and it seem to  work  for the G4  accepting to share  but the mac book pro recognize the connection  but says  that it is a protocol not recognized  ..could someone has a clue if it works ?   do i have to install  something special to do it ? 
i d like to have access  to the hard disk  connected to the g4 from the macbook pro in mac os 10  .7
thanks in advance for the one who will answer
