Installing Leopard on Parallel

I have been working on getting Mac OS X 10.5 (Leopard) installed on to my iMac via Parallel. The reason I wanted to do this is because I have some software that only run's in 10.5, and it will be very expensive to upgrade to work with (10.8.2)

There were 2 big issues that I had to deal with:

1. I wasn't creating the correct disk image for Parallel to use

Part of the core problem was that the Parallels log file wasn't telling me what was going on. I would see lots of PET_VM_EVT_VM_CONFIG_CHANGED, PET_DSP_EVT_VM_DEV_STATE_CHANGED and PRL_WNG_NO_OPERATION_SYSTEM_INSTALLED. But no clue what is going on. Basically if you get the 'Click Start' to launch after a few seconds after starting the process it means that your Disk Image is bad.

Thanks to some information over on MacFixIt, I was able to correct identify how to properly burn a disk image of an OS disk. ( I wasn't selecting the core device.)

2. I was unable to modify a disk image.

This is a problem with Mountain Lion and not something that you did. Apple updated the DiskCopy tool so that DVD master disks are read only. To get around this, I had to boot up my old computer and then created the disk image on that machine. That created the opportunity for me to edit the disk image.

Looks like I am in business and looking forward to installing my applications!
