VB not recognising disk

[AnotherEye]

My first post, I'm new to VB.
I've tried to create aVirtual machine without success:
* Mac OS 10.4.3: I have the install DVD but VB does not see it (is this because it's not for installing with an intel mac?). Is there a workround?

thanks in advance

I'm running Mac OS 10.7.3 Processor: 2.16 Ghz Intel Core 2 Duo

If you're trying to create a Mac OS X guest (virtual machine) using 10.4.3 then you're out of luck. 10.4.3 was the last retail version of 10.4 and it only supported Power PC Macs not the Intel ones.

VirtualBox is a virtualizer that can run a different Intel guest OS (like Microsoft Windows) on Intel CPUs running a different Intel host OS (like Mac OS X), it's not an emulator that can emulate another CPU (Power PC) on an Intel processor.

You'd need a 10.4.4 (or above) install disc (that came bundled with one of the Intel-based Macs) which was the first version that supported Intel processors. In your case you'd need a 10.4.8 disc that came bundled with the 2.16 Core 2 Duo MacBook Pro or a 10.4.7 disc that came bundled with the 2.16 Core 2 Duo iMac (depending on which Mac you have, you didn't include the model in your post). The installer does some hardware checks during installation that would keep you from using a different 10.4.4 or above install disc that did not come with those Macs. There are a couple of tricks you can use to get around that but they can't be discussed on these forums, and you can only legally virtualize OS X Server Leopard (10.5) and above, and only on Mac hardware.

thanks RPMurray.
I guess 10.5 or 10.6 would be OK, all I really need is to run Rossetta so I can use some of the software that I used on my G5.

If you have the original OS X install discs that came with your Mac then you could use those. They would pass the hardware checks, as would any of the retail 10.5 or 10.6 discs.

thanks again rpm.
I just bought the iMac on eBay. It came with Lion installed & I don't have the origanal disks.

You can make your own install dvd/disk image by following the instructions from this blog entry:

I did and it worked just fine.

thanks Jim but 10.7 doesn't support Rossetta which I need to run programmes that have not been adapted for the intel chip. I'll get hold of a 10.6 disk & install it on VB. I don't think there's another way!

Well, if you don't have a snow leopard install dvd, you can download the image from here:

One thing you need to be aware of is that a guest 10.5 or 10.6 will use up a whole core while the VM is running (roughly 100 to 105 percent), even if it's idle. It would probably be a good idea to have a least four gigs of RAM in the Mac to support both the host and the guest. The 10.5 or 10.6 guest OS will soak up about half a gig of RAM just running the guest OS (although Leopard uses about 100 megs less than Snow Leopard) before you even start running any programs on it. Two gigs total on the Mac may be a tight squeeze.

On the other hand, a 10.4 guest uses just 10 or 20 percent of a core while idle and only soaks up less than a quarter of a gig of RAM for the guest OS which would leave you with more RAM for any programs you'd run in the guest, and would also mean you could get by with less RAM overall.

Forgive me if I've got it wrong but that just seems to be an update for 10.7.
I need an earlier version unless it's possible to instal Rosetta on 10.7?
Thanks anyway Jim

Thanks RPM.
Was 10.4 ever made for intel macs? If so I'll go find a disk (Iguess it would have Rossetta).

Yes, like I said in a previous post above, 10.4.4 was the first OS X release to support Intel. The problem is that Apple never released 10.4.4 and above for retail sale. These disks came bundled with the Intel Macs as the system Install disks you'd get in the box with the computer. Most of these disks have built in checks in the installer to make sure that they could only be installed on the Mac model they were sold with. There are some later 10.4 version system Install disks (like 10.4.10) that can install on most of the Macs that shipped in 2006 and 2007. You may need to check on eBay and ask questions of the sellers to make sure you get one that will work with your Mac. The EveryMac website lists every Mac ever made and the versions of the OS (along with the build number) that came with them. For example, the Core 2 Duo 2.16 GHz 24-inch display iMac came with 10.4.7 (8K1123).

Yes, any of these 10.4 disks will come with Rosetta.

thank you RPM.

I now know what to look for.

I just did some research to verify what I said. There was a retail version of 10.4.6 that Apple sold but it was just for the Power PC Macs, so be careful you don't get that one.
