Which mac are you wanting to download Mac OS X Yosemite on, model and year.
With this video I want to show you how we can create an installation usb with mac os YOSEMITE 10.10Link for download Mac OS X Yosemite 10.10 DMGhttps://suppo. Oct 16, 2014 If you don't want to use Diskmaker X, Apple has actually included a terminal command that can create an install disk for you. Assuming that you have the OS X Yosemite installer in your.
Some macs that came preinstalled with an OS newer than Mac OS X Yosemite cannot
do the conversion from InstallOSX.pkg to Install OS X Yosemite.app.
If the 'donor' mac is too new to convert the InstallOSX.pkg to Install OS X Yosemite.app
do you have a copy of the Snow Leopard DVD install disk.
If the mac running Big Sur is the right age to create the Yosemite installer app
click on the link below.
Go to Download macOS and click on OS X Yosemite 10.10
this downloads InstallMacOSX.dmg to your Downloads folder.
The next section can only be done on a mac that is capable of running Yosemite.
This includes macs that have the potential to run Yosemite but have been upgraded to a newer OS.
A mac that came preinstalled with an OS later than Yosemite will refuse to do the next bit.
When downloaded open to InstallMacOSX.pkg, double-click on
that and an installation window will open, this does not install Yosemite
but converts the InstallMacOSX.pkg to the Install OS X Yosemite.app which
you will find in your Applications folder.
(If the installation window asks which disk you want to install to, you must pick
the disk that you are booted to at the time. Not any internal or external disk that
you want to eventually install Yosemite on, that is for later.)
Create a bootable USB installer disk using the Install OS X Yosemite.app
in the Applications folder and the createinstallmedia command in the Terminal app.

There are many ways that you can create a bootable Mavericks USB Drive but this seems to me the far easiest way to do so. In this article I will assume that you already have a reasonable grasp of the OSX system and cut out the lengthy text:
1. Download Yosemite from the Apple Store
Yosemite can be downloaded directly from Apple Store here. After download it will try and install automatically on your Mac. Just cancel out of this.
2. Verify the Installation Files are present
Head over to your Applications folder and check that there is a file which says Install Yosemite
2. Prepare a USB Flash Drive (Must be 8Gb or larger)
Install Disk Creator Yosemite Windows 10
- Plug the USB Drive in to your Mac and open “Disk Utility” (found under applications / utilities in finder)
- Select the USB Drive
- Select the Erase tab
- Ensure that the format is Mac OS Extended (Journaled)
IMPORTANT – Leave the name as “Untitled”. If you change this the next step won’t work
3. Create the Bootable Yosemite USB Drive
Open up Terminal (found in applications)
Type this in:
Wait for the process to complete. Done.
4. Boot from the Yosemite USB Drive
Restart your computer and hold down “Option”. You can now select the USB Drive you just created.
