#HOW TO MAKE MAC OS X ISO BOOTABLE PASSWORD#

Connect to your Mac the properly formatted hard drive or flash drive you want to use for your bootable Yosemite installer.

Drag the BaseSystem.dmg icon into the Source field on the right (if it isnвЂ™t already there).

Select BaseSystem.dmg in Disk UtilityвЂ™s sidebar, and then click the Restore button in the main part of the window.

#HOW TO MAKE MAC OS X ISO BOOTABLE INSTALL#

Launch Disk Utility (in /Applications/Utilities) and then drag BaseSystem.dmg (in the OS X Install ESD volume) into Disk UtilityвЂ™s left-hand sidebar.

(This tells the Finder to show hidden files-weвЂ™ll re-hide such files later.) Open the Terminal app (in /Application/Utilities), then type (or copy and paste) the following command, and then press Return:Дefaults write AppleShowAllFiles 1 & killall Finder

Several of the files youвЂ™ll need to work with are hidden in the Finder, and you need to make them visible.

That volume will appear in the Finder as OS X Install ESD open it to view its contents.

Double-click InstallESD.dmg in the Finder to mount its volume.

In the folder that appears, open Contents, then open Shared Support youвЂ™ll see a disk image file called InstallESD.dmg.

Right-click (or Control+click) the installer, and choose Show Package Contents from the resulting contextual menu.

ItвЂ™s called Install OS X Yosemite.app and it should have been downloaded to your main Applications folder (/Applications).

Once youвЂ™ve downloaded Yosemite, find the installer on your Mac.

Right-click (or Control+click) the Yosemite installer to view its contents. The procedure is a bit more involved with Yosemite than it was for Mavericks (which was itself a bit more involved than under Mountain Lion and Lion).

Here are the steps for using it to create your installer drive. YouвЂ™ll find Disk Utility, a handy app that ships with OS X, in /Applications/Utilities. If you like, you can rename the drive from its default name of Install OS X Yosemite, though I think itвЂ™s kind of a catchy name. You now have a bootable Yosemite install drive. (see the screenshot above), which could take as long as 20 or 30 minutes, depending on how fast your Mac can copy data to your destination drive. Wait until you see the text Copy Complete. The program then tells you itвЂ™s copying the installer files, making the disk bootable, and copying boot files. The Terminal window displays the progress of the process, in a very Terminal sort of way, by displaying a textual representation of a progress bar: Erasing Disk: 0%вЂ¦ 10 percentвЂ¦20 percentвЂ¦ and so on.

Type your admin-level account password when prompted, and then press Return.

Paste the copied command into Terminal and press Return.

Warning: This step will erase the destination drive or partition, so make sure that it doesnвЂ™t contain any valuable data.

Launch Terminal (in /Applications/Utilities).

Sudo /Applications/Install OS X Yosemite.app/Contents/Resources/createinstallmedia -volume /Volumes/Untitled -applicationpath /Applications/Install OS X Yosemite.app -nointeraction

Select the text of this Terminal command and copy it:.

This means that if you moved it before installing Yosemite, you need to move it back before making your installer disk. (The Terminal command used here assumes the drive is named Untitled.) Also, make sure the Yosemite installer, called Install OS X Yosemite.app, is in its default location in your main Applications folder (/Applications).

Connect to your Mac a properly formatted 8GB (or larger) drive, and rename the drive Untitled.

Using the createinstallmedia command in Terminal Here are the required steps: (Follow this tutorial to properly format the drive.) Your OS X user account must also have administrator privileges. That drive must also be formatted with a GUID Partition Table. Whichever method you use, you need a Mac-formatted drive (a hard drive, solid-state drive, thumb drive, or USB stick) thatвЂ™s big enough to hold the installer and all its data-I recommend at least an 8GB flash drive.

The Disk Utility-via-Terminal approach is for the shell junkies out there. The Disk Utility method is the way to go for people who are more comfortable in the Finder (though it does require a couple Terminal commands), and it works under Snow Leopard, Lion, Mountain Lion, Mavericks, and Yosemite. (Note that the createinstallmedia tool doesnвЂ™t work under OS X 10.6 Snow Leopard-it requires OS X 10.7 Lion or later.) The createinstallmedia method is the easiest if youвЂ™re at all comfortable using Terminal, itвЂ™s the approach that I recommend you try first. IвЂ™ve come up with three ways you can create a bootable OS X install drive for the Yosemite: using the installerвЂ™s built-in createinstallmedia tool using Disk Utility or performing the Disk Utility procedure using Terminal.
