What options do I have to connect my new MBPr to my iMac?

 

I have set a WIFI network between the two, but I can't use it and access Internet simultaneously.

 

Can I use a FireWire 800 cable between the two, other than in Target mode? I guess not. I have the TB-FW adapter, but I don't dare to plug them together live to try!

    If you have a patch CAT cable (has the same interface as the ethernet jack, but the internal wiring is different) you can connect the two machines together and do stuff like internet or file sharing.

    Actaully, it does not matter if the cable is so-called patch or so-called crossover. Macs have had auto-sensing network ports since dinosaurs walked the earth. The cable should be a cat-5, cat-5e, or cat-6. If the computers are recent (since dinosaurs, &c.), cat-6 will be faster. You will then be able to access the internet via WiFi on either machine.

     

    Another way that is more limited is to boot one machine into FireWire Target Disk mode (search the help menu in your computer's Finder). That will permit the machine you did that to to mount its drive(s) as external drives on the machine to which you connect it. For this to work, each machine must have a FireWire 400 or 800 port that works, and you must have the necessary cable.

    Yes. From the Finder's Help menu, search for "Use IP over FireWire."

     

    If each computer has a network cable port, you can connect them using EITHER a "straight through" or "crossover" Autosensing means the Macs won't care.

    http://weather.nikola.com/tech_stuff.htm if questions re those cables.

     

    Unless I misunderstand, each kind of new MBPr that has a FW800 port also has an Ethernet port. What kind of machine (look under System Information for an identifier such as 9,2) do you have?
