Ok, having a ton of problems here so I'll start from the beginning.
Using a mid 2007 iMac with leopard is preventing me from using software that requires at least snow-leopard or newer.
I got a copy of Mountain lion and discovered I cannot install it unless I have Lion, and I cant install lion unless I have snow leopard.
I now have a dmg of snow leopard on my computer. When I try to open it, it says I must first burn it to a disc.
It's a 6gig file so I purchased Verbatim lightscribe 8x DVD+r DL which have 8.5gig of space.
I put the disc in my machine and after about 30 seconds it spits it out. I then try to put it in my macbook which already has snow leopard, it also spits it out.
In my about this mac section, under disc burning, DVD-write, it says this:
DVD-Write: -R, -R DL, -RW, +R, +R DL, +RW
I tried using disc utility to burn to an external drive but right as it begins to burn it says "Could not validate source - Resource busy"
I'm really frustrated here so any help would be great.
