Yes. It requires a "hack" to do, but it can be done and it works well. If you search on these forums, I'm sure it will be easy for you to find out how.

Also, this hack is not supported my Apple and voids the warranty. Correct me if I'm wrong....

Not really sure other than the fact that it's not supported or isn't guaranteed, but that's what I [thought] read here :D I know some people here have done the hack and would know for sure.

No it doesn't, it's simply a software modification and can be fixed by a simple formatting of the hard drive.


I really do wonder why people see the word 'hack' and imeaditly think it voids the warrantee.

You have to reformat the HD to undo it? I thought I read somewhere where you just have to "undo" something in the hack. Man I really made this complicated now :p

Probably because "hack" sounds so mischievous that is sounds as thought it could. But I could have sworn I read that it did void the warranty. Must have been wrong, oh well :eek: :)

Maybe? I've never had any reason to uninstall the hack on my computer, but I've lost the ability to span screens every time I reformat the computer.

what size is your imac? So you're saying that the ability went away with a reformat?

here's a link to a macworld article regarding this:

http://www.macworld.com/weblogs/edi...nning/index.php

Remember that you have a VGA out... the monitor needs to have a VGA input; if it is DVI only you need an adapter which runs ~$300

I haven't tried the hack, but I have heard that resetting the NVRAM (or whatever it is) restores the iMac to the original state regarding display properties.

I thought it was a firmware hack, which has nothing to do with the OS, there for it should work no matter what OS you have on your system...I think :D

Well at least it is advertized as a Firmware hack.
So that should not be bother by the OS then ;)

Look, people, if you don't know how this "hack" works (it's an Open Firmware patch), don't chime in with ill-informed advice.

You do NOT reverse this patch by formatting the hard disk. The patch is in the firmware and can be reversed by resetting the NVRAM - all you have to do is shut down and hold down Command-Option-P-R while turning on the computer.

It doesn't void your warranty. If you're worried about it, you can reset your firmware before having your computer serviced.

And yes, it works like a champ on the iMac G5. The patch is available as an easy-to-run applescript "Screen Spanning Doctor" available at http://macparts.de/ibook
