I could also boot from that DVD but in the end it told me I cannot start the installation from readonly media. I could create that image file and burn it to a double layer DVD. My first guess was to use the createInstallMedia tool together with an image file. That is an install DVD that would also create a recovery partition. Yesterday I was curious to find out if I would manage to create a complete install DVD of YOSEMITE. Thanks a lot for sharing your method with us! I see only one drawback. How to create a complete YOSEMITE install DVD Reboot with holding down the option key to test your 10.10 recovery partition. Wait a few minutes for it to finish and return back to a prompt. Open Terminal and type the following commands:Ĥ. Download and decompress the file recovery.sh.zip from and move recovery.sh into your Downloads folder if it's not there already.ģ. If you don't still have the installer, you can get it again by redownloading from your purchases tab in your mac app store.Ģ. Copy the InstallESD.dmg file into your Downloads folder.

Where lvUUID is the last lvUUID reported by the previous Terminal command. If it doesn't, you can make one by doing the following.įirstly, if the yosemite dvd makes a core storage logical volume, revert it to get partitions back to normal by running these 2 commands in terminal. I don't know yet if the yosemite dvd will create a recovery partition. Hence the terminal method instead.Īlso, the mavericks dvd did not make a recovery partition. It did actually make a bootable dvd, but when one attempted to use it to actually do an installation, it did not work. However I will say that when mavericks was publicly released experiments were made with that and attempts to make a bootable dvd with createinstallmedia did not work properly. I'm still going to wait for public release of yosemite. I'm not curious enough to waste a DL DVD to test it yet. Not sure if that will work with yosemite. Mount the InstallESD image to 'install_app' without verifying or opening Finder I've included comments detailing what each command does. I had issues burning on the MacBook Pro 13, so I copied it to my Windows PC and used imgburn which works just fine. Then burn the *.iso file created on the desktop.

So far this is confirmed with Developer Preview 1. So if you want to make issue over why I created a DVD guide vs USB, just don't waste your time. PLUS it's more economical to have a small CD booklet with each OS X version readily available for quick use.

The Mac must also be using macOS High Sierra or later, the latest version of macOS Sierra or the latest version of OS X El Capitan.I wanted to share a method I've borrowed (and tweaked) from other sites in regards to making a bootable Yosemite installation DVD that works.īefore going any further, I fully know and agree that DVD installation media is old and being phased out and replaced by bootable USB installer media.
