Grey discs can only be used with the machine model they came with. Black discs can be used with any machine that supports the version of OS X on the disc. You need a black disc.
 
Ah crap - thanks for the response again.

I'm just trying to get a temporary upgrade to get Time Machine since it makes things sooooooo easier.

Ok, so I've backed up this 10.4.11 system, and I have a legit 10.6.8 iso on a usb stick, but this system will not boot from the stick (tried holding the option key, and it only identified the internal HD).

My question is - should I make a DVD of the ISO and try that?
...

(Not a black disk, either)
AFAIK, Snow Leopard installer never came with something later than 10.6.3
There are later installers, but only on restore DVDs that came with specific Mac models, and won't install on other Macs. That's likely what that message is about "Mac OS X can't be installed on this computer… " The legitimate Snow Leopard installers come on white disks, with a graphic of a snow leopard on the label. 10.5 (Leopard) was the last system to come on a black disk - and, or course, Snow Leopard is the last OS X system to come on a DVD at all. :D
 
Apologies on taking such a long time to do this, but just to update, this rig is now running 10.6.8 with a 4TB Hybrid and T7600 Core 2 Duo.

I know I can up it to 10.7, but isn't there a file I have to delete or something? Can some explain the trick and how to go about it (or link me)?

The firmware is updated if that's helps.

Thanks!

Intell,

Read the post, but I have some questions before I proceed with this.

1.) Obviously I'm going to partition the drive to try this install out. But here's the confusing part. According to that link it says, "There is a small gotcha to this, is that you need to install Lion to a supported platform first (such as a Core 2 Duo), then migrate that installation to the unsupported platform."

My school laptop is a Mac running 10.10, where I have a copy of the 10.7 installer (legit) for the "unsupported"/rebuilt Mac. Furthermore, the Mac I was rebuilding now has a Core 2 Duo and the firmware update. So how would I go about installing 10.7 on the rebuild? And is the rebuild still considered unsupported even though it has the right processor and firmware update?

2.) While we're at it, and I guess this ties into the last question, when do you remove that .plist file? On the supported platform? Do I still need to do this even though the Core 2 Duo is a 64 bit chip?

I know I'm probably wrong somewhere, but I want to get this right before I try anything stupid.

Thanks!

Ok, so I went ahead and figured this out.

To benefit those who upgraded their old machines to a C2D, you need to do the following.

First, go here and follow the instructions to install until you get to the PlatformSupport.plist file:

http://www.insanelymac.com/forum/to...on-on-any-coreduo-mac-upgraded-to-a-core2duo/

Now, instead of deleting that plist file, on page 2 of that link, use terminal and the vi editor to edit the file to add your particular Mac. I used the identifier from this link:

http://vureyosx.blogspot.com/2011/07/how-to-install-os-x-lion-107-on.html

I should note that you're going to have to edit this .plist file twice. Once on the initial install and then again for the combo update. The update re-writes the .plist file, so either save a backup file or re-do it. It takes 2 minutes.

It works with installing and the combination update to 10.7.5. Boom!

VV5 out.

Thanks for the update and the link. It's an interesting read, and would be very helpful to someone trying to upgrade one of these machines.
 
Thanks archtopshop. Going forward, should any users have any question on this process, please feel free to post or PM me.
