After 6 hours on the phone, 8 hours on the internet and 4 hours in the mac store i still dont have a solution to this! :
I have a MBA which i connect to my Mac Pro via Thunderbolt to Firewire 800 (with a connector)
My MBA sees my Mac Pro in the finder and vice versus but the connection fails. I am also NOT prompted to enter user name and password if i click "Connect As"
After 4 hours in the Mac store the problem was solved, it worked for a few days and now its not working again.
Im not an expert on networking but here is what i know and what i remember that happened:
It is an ad hoc network i am trying to create.
We managed to get it to work when one computer was using DHCP with a manual address.
It would not work when both computers were just using DHCP
In the network preferences both computers show the network with a green light and say connected.
I do have a theory why it is not working but do not know if its right........i think that the ip address has been changed when my MBA has been restarted. So when connected to the Mac Pro it is trying ot find the old IP address????? Not sure if this is correct.
I also have a MBP and this connects seamlessly via firewire 800 to my Mac Pro. I can see everything on both computers through the finder....no problem!
If anyone out there has an answer to this it would be very helpful however........
Please do not tell me it cannot be done as it took 7 "Mac Genius' to make it work and they did it successfully. Also i dont want to use Target disk mode (i know all about this already)
All 3 computers are running the most up-to-date version of Mountain Lion 10.8.2
Please please please help
thanks in advance
