Let’s start with the process of burning a Mac OS X installer in DMG format (InstallESD.DMG) to a DVD in Windows environment. Steps to burn DMG file to a bootable macOS DVD in Windows Eventually, I restored my iMac to OS X 10.8 using the same DVD as macOS installation disc. Later, I found a way to burn macOS DMG file to a bootable DVD on my Windows laptop. The only option left for me was buying an OS X Lion Installer disc as the Internet Recovery required a lot of bandwidth and time. I accidentally formatted the hard disk of my iMac and lost the recovery partition in the process.

My first experience with burning a DMG file to DVD was actually on Windows, back in 2013, when Mountain Lion was the operating system. A macOS installation package with DMG extension enables creating bootable installer DVDs. Therefore, it is possible to mount a DMG file on a virtual disk or write it to a DVD and access its contents.

However, these do tend to stick at certain points while the system's busy and the whole process should be done in just over an hour.DMG is a disk image format for Mac just like an ISO file in Windows. Small addition - when installing from DVD the progress bars will lead to you to believe it's actually going to take forever, if not slightly longer. I have had a successful boot and install from DVD on a MacBook (school's out for Easter so no access to a Mac Pro at the moment) so at least we know it's possible to create a working DVD installer. This should in theory be much quicker but I've not tried it out yet. Still, it's better to get there slowly than not at all -)Īlternatively, if you have a spare hard disk you could clone the Yosemite USB installer partition onto that using Disk Utility's Restore function. Be warned, booting from the Yosemite DVD will take a small eternity, the installation itself will take quite a bit longer.

If you can boot from the original Apple installation discs you should be able to boot from your newly created DVD, and hopefully it will appear as a boot option. You will need a dual-layer DVD for the burning operation. This should be listed in Disk Utility on the lower left pane - highlight it and select Burn. Select DVD/CD master as the image format then hit the Save button when you're ready.Īfter a few moments you will have a disk image with the extension. Highlight the partition Install OS X Yosemite on the upper left pane then go to File > New > Disk Image from "Install OS X Yosemite". If not, read on.įirst, mount your USB installer and then go to Disk Utility.

If you know how to do this then ignore the rest, grab a dual-layer DVD and get cracking. If your Mac Pro has issues with booting from USB but will boot from a DVD, create a DVD from the USB installer.
