SOLVED Using an older iMac as a monitor to a newer iMac

[Sapper]

I have a 20" iMac running OS10.9.5 and am wondering if this could be used in any way as a monitor for a 21.5" iMac (Retina 4K 2017) running OS 10.15.7.

Any guidance will be appreciated or do I have to get a more modern computer?

Regards

iMacs built between 2009 and 2014 can be run in Target Mode, as monitors for other Macs. Is your iMac one of these?

Hello Howard
It looks as though my old iMac is a 2007/8 model so presumably this cannot be used.

Howard is correct:

Use your iMac as a display with target display mode

Be well,

This is interesting, thanks. I have a 2011 - 27 inch iMac. So if I got a new Mac I could still use this Mac as a monitor, right? I know how to do Target Mode for transferring files. Same procedure?

Hi,

You should be able to - the process is mentioned in the article linked above.

Thanks Howard,

Well that was nice to see this will work with my 2010 iMacs. I have never used or heard of "Target Mode" are there articles here on the Step by Step or "Help" within the 2012 Mac Mini "Help Menu" running Catalina?

Hi,

Here is the link to the Apple article posted previously: Use your iMac as a display with target display mode

It explains the steps to use Target Display Mode. Let us know if you have additional questions.
