The process is almost identical to the Mavericks USB installer article from last year.

With the transfer completed and the files safely hidden again, the removable drive is ready to perform a clean or upgrade installation of OS X Yosemite. Enter the following command ( Figure O):ĭefaults write AppleShowAllFiles 0 | KillAll Finder While optional, it is generally not considered a good security measure to keep these files unhidden.

As a rule of thumb, unless specifically necessary to your daily functions on the computer, launch Terminal.app to enter the command to make the system files hidden again.

Again, the transfer time will depend greatly on the age of the machine ( Figure N).

To replace the alias, copy the Packages folder from Step #9 to the Installation directory.

Delete the Packages alias by right-clicking the file and selecting Move to Trash from the context menu ( Figure M). Navigate to the System | Installation directory where you will find an alias to the Packages folder.

Upon completing the file transfer, the drive will auto-mount in Finder.

However, by my experience, it is far shorter than what is stated by the progress bar ( Figure L).

The process can take several minutes to complete.

Enter the administrative credentials and click OK to execute the commands ( Figure K). Additionally, Disk Utility will request administrative authorization to perform the task.

Clicking Erase will initiate the process to install the files onto the drive.

Clicking the Restore button will prompt a confirmation message.

Also, drag the BaseSystem.dmg file from the finder window to the Source box ( Figure I).

Next, select the Restore tab and drag the partition from the device list to the Destination box.

Switch back to Disk Utility.app to select the partition name created in step #2.

With the contents of the InstallESD.dmg file visible, there are two files specifically that will be used to create the OS X installer to the removable drive: BaseSystem.dmg and the Packages folder ( Figure H).

Sort through the file hierarchy Contents | SharedSupport and mount the InstallESD.dmg file by double-clicking it ( Figure G).

Right-click the installer and select Show Package Contents from the context menu ( Figure F).

Navigate to the location where the OS X 10.10.

Enter the following command ( Figure E):ĭefaults write AppleShowAllFiles 1 | KillAll Finder

Launch Terminal.app to enter a command that will unhide the hidden files needed to complete the next few steps.

Once completed, the removable drive will be prepped for OS X ( Figure D).

Depending on the size of the drive, the changes typically take several minutes to process.

Click Partition to execute the changes ( Figure C).

Verify the changes to be made to the drive are correct, and then click Apply.

Select the radio button next to GUID Partition Table, clicking OK to accept the change ( Figure B).

Click the Options button to bring up the partition scheme menu.

Enter a name for the device, and select the format as Mac OS Extended (Journaled) from the drop-down list next to Format ( Figure A).

Under Partition Layout, select 1 Partition from the drop-down menu.

Select the drive you wish to use from the device list and click the Partition tab.

Insert the USB Flash Drive (or SD Card) into the Apple computer, and launch Disk Utility.app from the Applications | Utilities folder.

With that said, follow the steps below to create a bootable USB installer:

User Account with Administrative privileges.

Apple computer with Mac App Store (10.6.8+).

OS X 10.10 DP1.app (installer downloaded from Apple’s Mac Developer site).

It you decide to install beta software, you should do so on a sanitized, secondary device that meets requirements to minimize issues.īefore getting started, let’s review the requirements for creating a bootable drive: Additionally, certain applications may not work fully (or at all) until updates are made available.

Largely untested and full of bugs, this may lead to conflicts with production systems. Those interested in testing Yosemite may sign up for the OS X Beta Program, which will allow them to test the new OS, if selected.Ī word of caution, however, as beta software is just that. What about the end-user? Must we really wait until later this year to try out Apple’s latest OS? Maybe not. Continuing the naming trend, Yosemite was made available the same day as the WWDC event in the form of a Developer Preview beta for software developers to test their apps on the new platform. On June 2, 2014, Apple announced the next iteration of its powerful, yet elegant OS X operating system.
