I've done it this time. My imac needs help! My friend sent me a dmg image of a rescue disc but i have no burner on my imac. I only have a burner on my PCs. He made the image using disc utility in OS X. The cds i burnt in both Transmac and Nero(renamed .dmg to .iso) couldnt be booted from! My friend lives out of state and i dont know any mac users here. how do i burn a bootable os x disc utility image on a PC ?
