Can't reinstall my OS!

[jon millward]

Hay there, I have a power Mac G5 tower and it was running on OSX Leopard, I needed to reboot the computer so I backed up my files and began to reboot but on getting to the reinstall screen and asking to selected a hard drive and log onto my Apple ID I keep getting this on my screen (see image). It says this every time, I still have the Leopard disk but it won't open the disk drive from this screen saying "This item is temporarily unavailable"? I'm not sure but it seems like my computer won't install the new OS? If I could just reinstall the old Leopard disk then I'd be happy, does anyone have any ideas, thanks.

Hello and welcome.

-Which exact model of G5?
-Is the Leopard disc a retail copy or a gray OEM model-specific version?
-Do you have any third-party RAM installed?
-Have you tried an Open Firmware and NVRAM/PRAM reset?
-Your screenshot shows an attempt to install El Capitan from the App Store, which is not supported by the Power Mac G5.

hi,

I think it was produced in 2008 going by the date on the original hard drive? my leopard disc is a retail copy,
I have a couple of new memory sticks installed that are third part have had them couple of years (pictured) and yeah I thought that was probably the issue with El Capitan but I'd like to get it back onto Leopard if thats possible?

You actually have an Intel Mac Pro, not a Power Mac G5.

If you enter your serial number at this link, it will give the specific model number.

Check Your Service and Support Coverage

One thing I noticed in your photo, is you have two different kinds of RAM installed:

2 x PC2-5300 (with the 435F sticker)
2 x PC2 -6400 (Kingston)

Mac Pro (MacPro1,1) and Mac Pro (8-core) (MacPro2,1) take PC2-5300
Mac Pro (Early 2008) (MacPro3,1) takes PC2-6400

The mismatched pairs could definitely cause the issue.

OK, need some more important information.

1. What exact Mac OS are you using?

2. When you say "I erased the OS", what exactly did you do? Did you use Disk Utility to Erase and Format your internal drive?

3. Are you making backups to an external device? If you are, what software are you using?

4. Have you ever done any disk cleanup/maintenance/repairs, from a software perspective?

OK, need to know a couple of more things before we can proceed:

1. How exactly did you use Disk Utility? Did you boot the Macbook Pro from the Recovery HD partition and launched Disk Utility from there? Or, did you do it another way? It is critical that you describe exactly what you did.

2. It appears that you cannot boot up the Macbook Pro. If so, how are you making posts here? And if it is via another Mac, what exact Mac model is it?
