Thanks for the question and for giving all the details so we can confirm!
Yes, this is a good configuration with no special compatibility issues on that MBP. For development related tasks, the performance will be good on the Core 2 Duo. (And that Hengedock is really cool looking!)
A little more background:
The 13" MBP with nVidia 9400M GPU does not have switching Intel/nVidia graphics that is the main hazard with particular Mac hardware (and is only on the more recent 15/17" MBPs). So you’re good to go in terms of the Mac system. Some newer MBPs also need to have Apple’s latest firmware fixes to make external displays work well together, but I don’t think that’s a problem on your era of MBP.
Things to look out for:
- Make sure to use the latest DisplayLink Mac drivers, which is currently 1.6b3 http://displaylink.com/support/mac_do…
- Keep the OS X taskbar on one of your non-USB displays (because USB displays may come/go, and that has been known to cause problems).
And just generally, the DisplayLink drivers on Mac are beta quality relative to the Windows drivers. And because USB graphics doesn’t have explicit OS support, the drivers have to do a lot of tricks to get the OS to think there’s extra graphics outputs (that’s true on Windows, too) – so be cautious about OS updates until they’re confirmed compatible and/or drivers have a chance to catch up.
Thanks so much for your question! And feel free to let us know here if everything goes as expected, once you’re up and running.
