My friend has a 2009 27" iMac. For some unkonwn reasons, this iMac now could not boot succesfully recently.

 

As I know, this iMac could be used as an external display in "target display mode", right?

 

Could it be still used as an external display if it fails to boot (turned on) ?

 

Thanks !

You have to start into OS X to use it as an external display, so the hard disk must be fixed if you want to use it as an external display.

LousyFool is saying that the iMac is a computer easy to repair, at least with hard disk problems. However, you can't replace the hard disk yourself or you will avoid the warranty, so if the iMac is in warranty, you should take it to an Apple Store. If it's not in warranty, you can try to do it yourself

stanleyoowa, your friend should boot the Mac from the original OS X system disk that came with the Mac, then use Disk utility to check the internal HDD. Maybe it's not entirely gone but can be repaired. Eventually, it must be formatted newly and the OS re-installed. Only worst case a new HDD is due.

 

With the Mac being from 2009, there will be neither warranty no AppleCare anymore, so DIY might be in order in that worst case. There are instructions on the web. In any case, it being a 27" iMac, I find it sad to 'degrade' it to a 'display only' function...

    If it's a late 2009 iMac, yes.

     

    However, the computer inside what you are considering now 'display only' is certainly repairable, possibly with little effort. Keep telling where the boot process stalls, and which OS X version is on it?

    Yes, it is late 2009 27" iMac and the OS is 10.6.8.

    The boot process stops after a spinning circile showing up.

     

    Could this iMac solely be used as an external display even if it does not work as computer (due to something like hardisk failure, ....)
