The disk image is available here Download OS X Yosemite but if I mount and run it it says cannot install in your computer I need the installer to make a bootable drive like this( bootable installer). I will then run the drive in a separate apfs volume as told by apple here Installing macOS on a separate APFS volume - Apple Support
If the macOS that you want isn't compatible with your Mac or the currently installed macOS, the installer will let you know, and the App Store might prevent you from downloading it. For example, it might dim the Get button, say that the macOS is not compatible with this device, or say that the requested version of macOS is not available.

You don't need a bootable installer to upgrade macOS or reinstall macOS, but it can be useful if you want to install macOS on multiple computers without downloading the installer each time, or you're unable to install a compatible macOS from the Finder or macOS Recovery.
For information about the createinstallmedia command and the arguments you can use with it, make sure that the macOS installer is in your Applications folder, then enter the appropriate path in Terminal:
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:
This allows you to update any version of OS X from Snow Leopard, Lion, Mountain Lion, or Mavericks, directly to OS X Yosemite, with the installer that was just made. You can also perform a clean install (which we separately address in a thorough walkthrough here), or update multiple Macs without having to download it from the App Store again. Be sure to always back up the target Mac before updating OS X, whether to OS X 10.10 or any other version, you can follow detailed instructions on how to prepare a Mac for OS X Yosemite here. Enjoy OS X Yosemite!
Thank you, you saved my life. My USB was stuck in MBR partition scheme.How come the macOS installer does not format the USB drive by itself with the correct partition scheme? Or at least tell us that something is wrong?
Has anyone operating with Mavericks attempted to make a Yosemite installer USB drive using the Yosemite installer download?Apple HT201372 indicates the createinstallmedia command is to work only with the version of the OS X Installer app it came with. Does this mean to create Yosemite media the system must be running Yosemite?
Wingle. Considering that users update to OS X Yosemite from OS X Mavericks, hmm I suspect you did not even read the article here, describing how to make a USB installer drive for OS X Yosemite, from OS X Mavericks or OS X Yosemite, as long as you have the Yosemite installer downloaded. This article answers your questions and shows you how to create the installer drive with a USB disk of your choice.
I would suggest reading the article and then following the steps precisely, if you can not do that, then you should not try to make a USB installer and you should probably not install OS X Yosemite either. Maybe wait for the OS X El Capitan installer and use that in September.
The command does indeed format the drive and then place the installer files.If you used your external, this would have formatted the drive. Not the end of the world. You have an arduous task ahead to recover your files.
Thanks for the info.Is there a way to partition the USB so that the OS X installer only takes up the space it requires?I have a 16GB usb drive, but would like to put both the OS X installer and a Windows OS installer on that usb drive in two different bootable partition. Is that achievable?
I had a similar problem. My issue turned out to be that I had a slightly older version of the Yosemite installer. I had created it a while back, and it was version 1.65. As of today (12/26) the version is 1.67. Somehow the installer knows to check to see if you have the latest version. My suggestion to you is to download a fresh copy, and do it all over again. I was eventually able to get mine installed, and am using it to reply to you now. Happy Holidays.
I find it smarter to just install Yosemite with the installer to an external hdd or stick (dont know the required size of the stick) then boot up the recovery partition on the external device and install/update from that, no need to use terminal, and you will have an external OSX to boot for diagnostic use as well (very usefull to recover data from an unbootable internal drive, test software before installing or simply just have your own OS with you whithout having your to bring your Mac ).
Made the installer on USB stick, however contents of the drive only has the Install OS X Yosemite on it, none of the other elements these instructions show. (System, Library, Usr, etc). Did I do this incorrectly?
I followed the steps to create the usb drive, but now I am having trouble just loading the old os. How would I go about loading the old OS? Running yosemite from the usb is slow. I want to just stick with the old os. Thank you.
Make sure the command line current directory is not in the flash drive (/Volumes/Untitled or your flash drive name). It will fail to lock the drive. in my case this was the issue. I created the flash installer for Yosemite using a Mountain Lion (10.8) with createinstallmedia.
i have a simple problem,my hard drive jus got damaged and had to change it and my imac is when i bought it used to run on os lion ( the old version ) and now i changed the drive but i cant download the lion cause its not available on app and i cant run another installer like yoso or other versions of macintosh what can i do ?well i have only one imac and no more laptop to download or make bootable usbwhat should i do ?

Downloading and using different Mac OS installers is very common for troubleshooting purposes, for IT staff and admins, and for tinkerers. This article will discuss where to download and access installers for macOS Ventura 13, MacOS Monterey 12, macOS Big Sur 11, macOS Catalina, MacOS Mojave, MacOS High Sierra, macOS Sierra, Mac OS X El Capitan, OS X Yosemite, OS X Mavericks, Mac OS X Mountain Lion, Mac OS X Lion, Mac OS X Snow Leopard, Mac OS X Leopard, Mac OS X Tiger, and others too.
For earlier versions of Mac OS X, including Mac OS X Mavericks 10.9, Mac OS X Mountain Lion 10.8, Mac OS X Lion 10.7, Mac OS X Snow Leopard 10.6, Mac OS X Leopard 10.5, Mac OS X Tiger 10.4, and before, the process to obtain those installers differs a bit.
OS X Yosemite final version is available to download from App Store. Download and update it from OS X App Store or create a Bootable installer drive so you can easily use this installer USB drive to clean install OS X Yosemite or to install OS X 10.10 on multiple computer without downloading again and again on different computers. There a re few requirement before start following this guide.
When updating to a new version of macOS, it is recommended that you create yourinstall disk before running the macOS installer, as the installer may deleteitself (which would require you to download it again to create the install disk).
In rare cases, the macOS Catalina installer will say that it successfullycreated the install disk but actually create an empty Install macOS Catalinavolume. DropDMG includes a workaround to try to prevent this from happening, butif this occurs it should work if you simply choose the Create macOS InstallDisk command again.
For the best experience with macOS Catalina 10.15, be sure to keep your Office apps up-to-date. If the version of Office installed on your Mac is earlier than 16.16, and you are not being offered updates, you can download the latest Office for Mac suite installer. See About Office: What version of Office am I using?.
You may receive this error message if you do not have the installer for the applicable macOS version downloaded on your system. Before you run the command, please ensure to download the installer locally on your Mac, such as macOS Monterey, macOS Big Sur, macOS Catalina, macOS Mojave, or macOS High Sierra.
The required size of the USB flash drive depends on the macOS version that you wish to load. For example, the macOS Big Sur installer is 12.6GB, so you need to make sure it fits in the drive. Just to be on the safe side, it is best to use a 16GB USB flash drive; the larger it is, the better.
The macOS Monterey installer is available for download via App Store. So to get this Mac operating system version, launch App Store on your computer and type macOS Monterey in the search field. Choose the needed installer and then click Get to start downloading it. 2ff7e9595c
