Re: Installing Leopard on G4 iMac

[Neil Houghton]

Hi Walter,

Technically, you should be able to install Leopard on the late model 1.25GHz
G4 iMac.

License-wise, unless you got the family pack, you are only licensed to
install it on one machine (either the G4 or the intel but not both).

As far as I know, Apple doesn't have any active software measures to stop
you installing it on two machines - it's an honour system.

If you actually want to run Classic apps, you should stick to Tiger.

Regarding the Tiger upgrade DVD - I think that it will probably check for an
appropriate existing system before installing - if it can actually "see" the
existing Tiger system on your hard drive (even though it's not booting) you
MAY be able to run an erase & install directly over the old system.

I would think the easiest way would be just to try - the installer should
tell you if it needs a prior system present that it can't find.

Cheers


Neil

Re: Installing Leopard on G4 iMac

[F.W. Hänel]

Thanks Ronda and Neil,

I have found the original invoice and the machine is a G4 17" 1.25Ghz  
80GBHD with  Super Drive
so it should be suitable for Leopard ? I also have a full retail  
version of Leopard which I bought

to upgrade my current intel iMac.
Otherwise I would be happy to re-install Tiger as it gives me Classic  
as well.
If I install Tiger do I have to install Panther first or go straight  
to Tiger ?
But as I have only found a  "Mac OS X Tiger upgrade DVD" I probably  
will have to

install Panther first ?

Thanks

Walter

If you have the full retail version of Leopard, then you should be  
able to

boot from the install disk and do the erase and install.

BUT many of the G4 iMacs (eg mine!) are not supported for Leopard  
(processor
too slow) - in which case you will not be able to install from the  
Leopard

disk.

If your iMac is officially too slow there are ways around this -  
Google is

your friend - but you may find the performance very sluggish.

Also, if you are having hard disk problems, I would make sure the  
erased

disk checks out OK before spending too much time on set-up.


Cheers

Hi all,

I have a G4 lamp shade iMac which requires erase and install because
of some corruption
on its hard disk. Have not been able to solve it with Disk warrior or
Disk
utility. The screen remains grey.

The iMac came with Panther V 10.3 and was running Tiger until it
failed last week.
Can I install Leopard after the erase or do I have to start with
Panther then upgrade
to Tiger and then to Leopard ?

Looking for help,

thanks

Re: Installing Leopard on G4 iMac

Hi Walter,

If you have the full retail version of Leopard, then you should be able to
boot from the install disk and do the erase and install.

BUT many of the G4 iMacs (eg mine!) are not supported for Leopard (processor
too slow) - in which case you will not be able to install from the Leopard
disk.

If your iMac is officially too slow there are ways around this - Google is
your friend - but you may find the performance very sluggish.

Also, if you are having hard disk problems, I would make sure the erased
disk checks out OK before spending too much time on set-up.


Cheers

Hi Walter,

What are the details of your iMac, you need to check them to see if  
Leopard can be installed on it.

If it meets the specifications, you need to purchase a Leopard DVD.



Technical Specifications:
General requirements
	• Mac computer with an Intel, PowerPC G5, or PowerPC G4 (867MHz or  
faster) processor

• 512MB of memory
• DVD drive for installation
• 9GB of available disk space

Ronni
