View Full Version : System install problem on G5

Sep 6, 2009, 05:33 PM
I am having trouble installing the system on my G5. I recently wiped the drive in my MaPro running 10.6, and now both the system restore disk and an OSX 10.4 installer are refusing to let me install, reporting simply that the system cannot be installed in the drive. SMART status is fine, and the disk utility reports no problems. Any ideas?

The machine is a G5, 1.8 GHz, and the hard drive is the OEM drive.

this is confusing - a G5 is not a Mac Pro.

You cant install 10.6 on a G5 but you can on a Mac Pro.

Does that help?

No, what I did was put the drive in my Mac Pro, wiped it, then put it into my G5 and tried to install the system software.

putting the drive in the newer system, i bet that it got a GUID partion instead of the older (and needed for PPC) Apple Partition Map.

you could check by booting the G5 from the install media, go to Disk Utility and select the drive in the left pane. at the bottom it will show the info about the selected drive, and you are looking for the 'Partition Scheme'.

if it says 'GUID' then you need to click on the 'partition' tab, and then select the 'options' button at the bottom and check 'Apple Partition Map' and create the new partition (or multiple) with the correct partition scheme.

if it say 'Apple Partition Map', then you are on your own... no idea. best of luck.

stick the disc in your G5 and pop the install disc in the G5 and turn it on.

Why would you bother risking having an Intel Mac formatting... just use the G5 through disc utility.

Well, for whatever bizarre reason, I tried it again, and 10.4 installed just fine. Go figure.

Thanks for your help, anyway.
