hi I have a problem with an iMac late 2009 21.5 I want to connect to a new Mac Mini to use as a monitor with the Thunderbolt cable, the problem is that on the Apple support site does not say anything about 21.5 , since it is an important issue I would ask you the answers that are true as soon as possible, thank you.
iMac, OS X Yosemite (10.10.3)
Because as this says:
Target Display Mode: Frequently Asked Questions (FAQ) - Apple Support
Your model iMac is not supported
iMac Model | Cable Supported | Port on Source Computer |
iMac (27-inch Late 2009) | Mini DisplayPort to Mini DisplayPort | Mini DisplayPort or Thunderbolt |
iMac (27-inch Mid 2010) | Mini DisplayPort to Mini DisplayPort | Mini DisplayPort or Thunderbolt |
iMac (Mid 2011) | Thunderbolt to Thunderbolt | Thunderbolt |
| iMac (Mid 2012 and later) | Thunderbolt to Thunderbolt | Thunderbolt |
This app works pretty good with a wired ethernet/network connection
ok anyway but because of the Internet there are guides to do it ??
I do not understand what you are saying. Your model iMac does not support Target Display mode.

The late 21.5" 2009 iMac does not support Target Display Mode. This means your only alternative (assuming you want to keep trying) is to use a software solution called ScreenRecycler. However the performance will be slow. Please use Google to locate ScreenRecycler.
This question is asked very frequently so please don't ask if there are any other solutions, there are not.
