Hi all,

I just got my Leopard OS but I cant go any further with it past the first step.
I put the disc in and it tells me to restart and when it turns back on, it says "This software cannot be installed in this computer"

I'm using a first-gen PowerMac G5, upgraded with 2.5gb RAM, and a X850 ati video card. I checked the requirements for Leopard but am I still missing something here?

/cry

Have you got enough free space?

ladybugspider: Cute nick

The retail (boxed) version of 10.5 should install onto your G5 quite nicely. As long as you have at least one hard drive formatted as HFS Extended, with 6 GB of free space, then it should go through its checks and install.

The message you're getting could mean that someone has given you a copy of 10.5 that is either someone's Apple-supplied upgrade disc (in which case you need to have 10.4.x installed before you can upgrade) or you have a disc which came with an Intel-based Mac (which will flatly refuse to work on your PowerPC machine no matter what you do).

Spider - when it goes past the first "Use English for the main language" screen, if you utterly ignore the Welcome panel, can you see a menu item above, one of which is called: Utilities ?

If so, click once on the Utilities menu, and scroll down to: Disk Utility...

In Disk Utility, click once the name of your Hard Drive (on the left of the panel), and then click once on the Erase tab, on the top-right of the panel.

Then simply click once on the Erase... button.

and it should format your Hard Drive correctly for Leopard.

Note: if you have all your prescious stuff on that G5, it really will erase the lot, thus if you do, you need to back it all up elsewhere first!!

AddIt: Or erase it with your former Tiger Panther Installation Disc, as Mac OS Extended, or as Mac OS Extended (Journaled).

you shouldn't need to erase to install.
A simple archive and install will also work..

crud!!! I just bought a Macbook that had the installation disc with it so I thought I could use the same disc to upgrade my powermac. ugh, guess I have to head back to the store to get Leopard by itself >.<

My hardrive is currenting Mac OS Extended (Journaled) but I can't do anything to it, all the buttons and options in the partition tab are greyed out.

Thank you all for the quick responses ! <3

Ah-ha, I guessed right

The "drop in" DVD (which will bear the title 'Mac OS X 10.5 Upgrade') that was in your MacBook box will update any suitable Mac, PowerPC or Intel, that has at least 10.4.0 on it.

As you now have two Macs, buying a boxed copy of Leopard is a very good idea -- you get a ridgy-didge full installer of 10.5 that can be used on either your G5 or your MacBook. The licence that comes with the boxed copy will belong to yourG5, and the licence that belongs to the upgrade disc belongs to your MacBook, but if you ever come across a need to restore your MacBook's operating system you can use the boxed copy. If you didn't have the boxed version, if you ever needed to restore your MacBook you would have to install OSX twice -- once with the original 10.4 disks, and then doing the upgrade to 10.5. Messy and time-consuming.

I did not read it that way, he may have been lucky to get a MacBook with Leopard pre-installed, and therefore the Leopard installation disks are the MacBook installation disks, with all the stuff, and made just for the MacBook to use only.

If that's the case, there is no way you cut it to make it work on the other system.

ooookay.... i got the retail box Leopard in my dvd drive.... but nothing is happening... it pops the disc back out after like 20sec...

Try booting off the CD by holding down C at startup..

ladybugspider: that's not a good sign -- when your machine rejects the disc it usually means it can't figure out what the disc is. Your G5's optical drive has either an alignment problem or has a dirty pickup lens, or the 10.5 disc has a minor manufacturing fault making it unreadable (this has happened to a few other people, from my reading). See if your MacBook can read the 10.5 disc.

Out of curiosity, what kind of drive (make and model) do you have in the G5? You can find this information via the System Profiler, which lurks in /Applications/Utilities.

wally: holding down C didnt do anything for me

Brains: It reads fine on my macbook. I have to try several times putting it in the G5 before it detects the dvd but after i hit restart to start installing, it fails to detect it again.
I'm using a Pioneer DVD-RW DVR-106D

I got an external dvd drive from a friend and the installation disc is detected easily but I cant get the mac to boot from the external dvd drive.

Is there any way to make it boot from there with the disc in it?

if it's got a f/w connector you should be able to restart it as a target disc and load & install from there.


it that doesn't work then methinks you may have an Intel-only version of Leopard - or a stuffed optical drive as someone mentioned b4

Success! finally...


Solution:
-Link the Macbook and Powermac together with a firewire cable.
-Slot the installation disc into the Macbook.
-Restart Macbook.
-Hold down 'T' while restarting.
-On the Powermac, choose its own HD to install Leopard.
-Proceed with normal installation procedure with the Powermac.
-yay!
