I have a 13" MacBook and a 24" iMac. There's certain software I only have on the MacBook; is there a way I can connect my MacBook to the iMac so I can work on the bigger screen?
Nope. The video connector is video out only.
Your best bet is to use screen sharing to control the MacBook. Your won't get a "bigger screen" (as in, more resolution), but you'll have a larger surface area to work with.
Thanks, that's great. May not be optimal for resolution and speed but it is what I'm after.
Is it any different with the MacBook Pro? An old colleague used to plug his into a PC monitor - I wasn't interested at the time but I now wonder what kind of set up he had.
