<![CDATA[The Ins and Outs of Macs]]>Hello folks.

I'm designing a projection installation - at the moment it looks like i might be able to achieve what i want with 4 projectors. problem is that it needs to be one big projector on one floor, and 3 smaller projectors upstairs, with a 30m+ cable run down the corridor and up the staircase.

I think the best way to sync mov files will be to have a mac on each floor, networked together with one machine sending a control timecode to its Movie Player and the Movie Players on the other machine.

The problem is this: I have a 2013 Retina MacBook with 2 x thunderbolt and 1 x HDMI. - fine for 3 projectors, but no RJ45 port (i tend to use a thunderbolt to RJ45 adapter) The other machine is a Mac Mini with 2 x thunderbolt and 1 x HDMI and RJ45. But, if I use this machine for the 3 projectors, I don't get a control screen.

Possible solution: Use the laptop for the 3 projectors (with control screen on the main display - makes sense) and the Mini for the single projector and a monitor.

Question: Does anyone have experience of using a USB to RJ45 adapter/external network device? I have a couple of USB3 ports on the laptop that are free. Is this a solution? Or any other ideas? (that don't involve Matrox display adaptors - i have a couple of DH2Gs and they generally piss me off whenever i try to use them)

cheers!

A switch won't act like a router does and assign IP addresses (ie act like a DHCP server), so you will probably have to manually configure the network settings on both machines to make sure they're on the same network. A quick internet search reveals many articles on how to do this, if you don't know already. And yes, I know you hate networks :-)

And since I am not a Mac expert I won't talk you through it in case I mislead you.

so, i got paid for a job i did earlier this year, and bought a USB3 to RJ45 adaptor and a gigabit switch. (you're right Lucas - the switches are much cheaper than i expected)

i plug up my 2 machines into the switch and i get a yellow dot in the Network preferences, and no data streaming from Izzy to Izzy. is it because the network has a Self-Assigned IP address? what am i doing wrong? any ideas?

The 8-port gigabit ethernet switches I just got weren't super-expensive. I bought them new for around $30 USD each, so if the recycling centre doesn't pan out,  it shouldn't cost you an arm and a leg to purchase.

It's a pain sometimes to be sure. But I've had no problem networking Macs by hardwiring them to a gigabit switch. I generally have my control computer in the booth and have a LAN with a gigabit switch and send a run of Cat6 to the tech table to control the show computer remotely from my laptop so that I don't have to run signal from the projectors to the tech table, and then dismantle and re-run to the booth when we break down tech tables.

(i hate setting up networks)

I've only ever used USB to RJ45 for my Macbook Pro and it's worked fine for me
