How to Compress Mac OS X Leopard to a Single Layer DVD

OSX86 users who are trying to use Retail Install method needs to burn Leopard Disk on DVD. Since the size of leopard DVD is more than 6.4 GB so you need to burn a Dual Layer Disk. Most of us having Single Layer DVD writers. Some have Dual Layer writers but finding a blank disc is also a pain. So here’s a short and quick foolproof guide to making a SL-DVD leopard install disc. Cheers to rathalos for superb n easy instructions.

What you need
1. Original Leopard developers seed (.dmg)(6.55Gb)
2. One blank DVD (+1 backup blank just in case you screw up)
