Mac Os X Yosemite Install Dvd Download [EXCLUSIVE]

I am restoring a 2008 iMac to basically factory settings and want to reinstall Yosemite as the OS. I've tried booting the iMac and reinstalling the OS (El Capitan) but it failed saying that it couldn't find the package (?). I have erased the hard drive as I wanted a clean slate and this method (wipe then reinstall) has worked fine for me in the past.

Mac Os X Yosemite Install Dvd Download


So my next option is to create a bootable USB pen which is where I'm having trouble. I have downloaded the Yosemite installer dmg. I have a MacBook Pro M1 and when I mount and then try to run the Yosemite installer, of course it crashes out with the error saying I can't install it on this computer. Without the installer running in the Applications folder, I can't follow any of the steps on the Apple Support site (createinstaller terminal code process) or via any tutorials on YouTube or whatever comes up on Google.

However, I found an article with information on how to download the Snow Leopard iso and further in the thread it talks about how to turn that into a bootable USB pen using Big Sur - -to-create-a-bootable-os-x-snow-leopard-usb-drive

I'm pretty sure you can't buy installer discs from Apple anymore (Lion was the last version they sold an installer for, and that was a USB key, not a DVD. But you can make your own in several different ways:

Create a USB installer with the createinstallmedia tool included in the downloadable installer. See @onik's answer, or Apple Support Article HT201372: "Create a bootable installer for OS X Mavericks or Yosemite". Note that it omits an important first step: make sure the USB disk is formatted with the GPT partition scheme, and the volume you're going to use for the installer is in Mac OS Extended (Journaled) format.

If you really want to make an installer DVD, there's a posting on the MacRumors forum by tywebb13 that gives a command-line procedure for making a disk image that you can burn to DVD. I haven't tested it, but I'll include it here in case that source goes away:

It seems that Apple doesn't supply OSX on a retail DVD anymore, since all modern Macs have a recovery partition, which contains the installer and is updateable. However, there are ways to create an installer USB drive, and here is Apple's own solution.

You can then use the createinstallmedia tool to convert the volume from step two into a bootable installer based off the installer app from step one. To learn how to use createinstallmedia, use the following command in Terminal:

For example, assuming you have a volume mounted at /Volumes/MyVolume and the OS X installer app is at /Applications/Install\ OS\ X\ you could erase /Volumes/MyVolume and convert it into a bootable installer with this command:

You may need to adjust the path to the OS X installer app and/or your removable media device's name in the command. createinstallmedia is an advanced option for system administrators and as such, requires some knowledge of the command line in order to be used properly. It is only intended to be used with the version of the OS X Installer app it came with.

I recommend making one for Yosemite, on an external hard drive or USB thumb drive, for many of the same reasons I recommend making a bootable Mavericks installer drive: If you want to install Yosemite on multiple Macs, using a bootable installer drive can be more convenient than downloading or copying the entire installer to each computer. If you want to erase the drive on a Mac before installing Yosemite, or start over at any time, you can use a dedicated installer drive to boot that Mac, erase its drive, and then install the OS clean and restore whatever data you need from a backup. And if your Mac is experiencing problems, a bootable installer drive makes a handy emergency disk.

Now that OS X Yosemite is available, many users may wish to create a bootable installer drive from something like a USB flash thumb drive or another disk. This allows for several things, the ability to upgrade multiple Macs without having to re-download the installer, the ability to perform a clean install, and also the convenience of having a separate bootable reinstallation drive in the event you need it for serving a Mac.

The next step will actually make the installer drive from the previously formatted USB disk. If you already have the OS X Yosemite installer application in the /Applications/ folder on the Mac, you can skip directly to step 3:
