Installing OSX 10.4 on Intel MacPro

[PhillB]

Hi,

Is it possible to install OSX 10.4 on an Intel MacPro? I need to run Avid Media Station but it only works under 10.4. The only Macs I have are MacPros and I can't just get an older Mac to run Media Station on as I beleive it also requres Protools HD to be connected and all my Protools core cards are PCIe so wouldn't work in an older PowerMac.

If it is possible to install OSX 10.4 any idea where I might get the required installation DVD or image from?

Thanks,

Phill.

AFAIK, you can't install any OS version that pre-dates the version the Mac shipped with. So if it shipped with Leopard or Snow Leopard then you're pretty much SOL.

Can you be more specific, which Mac Pro do you have? If it is the first one (August 2006) then yes you would be able to install it. If you have a January 2008 or newer model you will not be able to get Tiger installed.

That is not entirely true. My MacBook Pro shipped to me with Leopard install yet I was able to put 10.4 on it because those MacBook Pros were being manufactured in mid 2007 to early 2008.

You cannot downgrade your Mac to an OS that didn't originally ship with that Mac. (Being nitpicky )

If your Mac Pro was purchased before October 2007; you can put Tiger on it. However, since you're asking, I'm guessing you can't or else you would have the Install Discs for Tiger (that would have shipped with your Mac).

Thanks all for the help.

I was being a prat. Its a MacPro 1.1 and when you mentioned it would have come with Tiger discs I checked and it did and I had them still. Installed fine on a separete drive to dual boot to.

Out of interest, if you split a drive into two partitions using the Mac disc utility, does it preserve the original partition? Wasn't sure hence going the separate disc route so as not to have to reinstall Snow Leopard etc.

One final question, never sure what Partition Map Scheme and Format type is best to use? Is there any performance differences between the different types such as GUID and Apple Partition Table and Mac OS, OS Extended and OS Extended (Journaled)?

Thanks again for the help,

You didn't even have to go buy tiger, awesome.

If it's intel-based, you it should use the GPT (GUID), (not sure if it will give you an option to choose the APM if you're installing Tiger.)
I would recommend the OS Extended (HFS+) Journaled, because that's now become the default format since Leopard.

EDIT: Be sure to:
1. Back up everything before partitioning
2. Use the disk utility from the Leopard OS disk because it will let you resize the volume/partition without erasing your current data. The disk utility from Tiger will wipe everything, then allow you to partition/change volume size.

GPT is best, unless you have support concerns for other OSs. (Note: Windows Vista/7, and most Linux distros, are fine with using GPT disks for data. I have a GPT disk I use for backups on both my machines, with HFS+ and NTFS partitions. Win 7 has no problems at all reading the NTFS side, and properly recognizes it as being GPT). You will need APM for booting a PPC Mac. Newer 64bit versions of Windows COULD boot from GPT disks if Apple didn't use an older version of the EFI spec.
