Can I connect iMac (24"Early09) miniDisplayPort "Primary Computer" to iMac (24"Mid07) miniDVI "ExtMonitor" using TargetDisplayMode. (Found a mini-DVI to mini DisplayPort connecter with USB power and audio passthrough online.) Possible?

Going with No, if I understand the question correctly.

If you are trying to connect iMac A to iMac B through their video out ports, then this is not going to work.

Target mode calls for A and B to be connected via a Firewire cable; 800, 400 or 800/400.

The MiniDisplay port and the mini-DVD ports are both outbound ports and will not receive a signal.

I am trying to connect my iMac (24"Mid07) miniDVI "ExtMonitor" to my iMac (24"Early09) miniDisplayPort "Primary Computer" using TargetDisplayMode. I want my iMac (24"Mid07) miniDVI to act as an additional display monitor for my iMac (24"Early09) miniDisplayPort "Primary Computer". I believe you are referring to Target DISK Mode, which utilizes a connected computer to a primary computer as an external hard drive that mounts on the primary computer's desktop.

Sorry, yes I was confusing the two.

However, while checking out the correct thing I note that everyone talks about doing this with a Thunderbolt cable, something your machines cannot use.

However, I did come across this article on the Apple site:

Seems to include at least one of your machines.

Sorry about the earlier mixup

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
