How to use my broken Imac as a second display for my new IMAc

Hi everyone !

I have a old Imac Imac 24" Intel Core 2 Duo 2.16GHz 2G

One day I was watching a video from youtube and It frozen. After that When I start the computer I get the Apple sound and a grey screen.

I send it to Apple assistence They said it could either be the the main board or the video board.

As they don't have this parts anymore couse it's a old Imac version, they can do nothing to help or make sure.

So I have this machine side by side with my new Imac 21.5 inch 2.5ghz Intel core i5

So is there a way to make it as a second display? Or do anything with it?

Obs: I used a ethernet cable to erase my Imac 24 and now I getting the grey screen with a file Icon with (?) inside

Please don't tell me to trow it way..... 🙂

Hope to get some help.

If it's either the main board or the video card then the old iMac cannot be used as an external display. Considering the machien is likely 7+ years old, it is probably time to just retire it. If you want to have a second display then it may be much easier to get an external display and connect it up. You have many choices available but sadly your old iMac is not one of them.

Even IF your old imac was working perfectly it isn't capable of serving as a display, it's not capable of video in. You need a Late 2009 27" or later imac.

Hi,

I am getting the this:

Hardware test does not support this machine.

When I bought This computer it came with OSx 10.4.7

Few weeks later Came out OSx Leopart 10.5 And the store gave me a update disk as a gift.

When Osx snow Leopard came out I bought it.

So my machine is ruining with Snow Leopard 10.6.8

When I try to run Hardware test from Snow leopard, nothing happens, also nothing happens to update disk. It only load hardware test from the first Cd that came with the computer. OSx 10.4.7

So After it load, it asked to choose the language and O got the this:

Hardware test does not support this machine.

iis this the Tiger 10.4.x disc that shipped with your IMac, if it is from another Mac it will not work. You may have to take it to an AASP to be professionaly diagnosed.
