Onyx 10.10.1 Mac App Store

Since both implement changes in how the drives file system interface with the computer, only solution 1 will work to create a recovery partition since it must be done prior to the drives running the commands, which will create a Fusion Drive or Core Storage volume.

Onyx 10.10.1 Mac App Store

Being the first OS deployed specifically through the Mac App Store, a recovery partition was created during the installationupgrade process that contained the files necessary to reinstall OS X should it be necessary in the future.

While the process is largely successful, there are times when the previous recovery HD partition is either deleted during upgrade or never created for reasons unknown.

Ive written about Recovery Partition Creator by Christopher Silvertooth, which has been a heaven send as the small, yet powerful app essentially scripts the entire creation process in minutes.

Sadly, the script is not compatible with Apples latest OS Yosemite, and the introduction of Fusion Drives and Core Storage further complicate matters, making restoring the recovery partition a largely futile effort.

There are, however, two ways to successfully restore the recovery partition.

Reinstalling OS X -- even over an existing 10.10 install -- will trigger the installer to recreate the recovery partition.

A downside is that you have to wait to reinstall OS X all over again.

Also, depending on the version of OS X currently installed on your Mac, the installer being used may be older than the current OS level, which might lead to system instability down the line.

The clone image can be stored on another partition either internally or externally and will appear as a selection to boot to when accessing Apples boot manager screen when pressing Option during the startup process.

Though not necessary, CCC offers the ability to also clone the recovery partition on a Mac and using that image, it can also be used to create a recovery partition on an internal or external drive using a non-destructive process.

It can even clone the recovery partition from another Apple computer and use that to restore the partition on another Mac that is missing the partition.

This is extremely useful, especially considering that CCC can run either locally or externally from a USB flash drive or hard drive to recreate the recovery drive on an internal SSD or HDD.

Select the source drive from the Volumes section in CCC and initiate a backup task.

The process should complete successfully after a few minutes.

Insert the media with the recently cloned recovery HD and boot into it on the destination computer.

Once on the desktop, launch CCC, this time selecting the destination volume, and then click the Recovery HD.

A new window will come down and identify that the volume is missing the recovery partition.

Click the Create Recovery HD button and follow the steps to restore it from the cloned source to the destination.

The processes will unmount the destination drive and repartition a separate 1 GB partition to be used to copy the recovery HD to.

Once the recovery HD is restored, reboot the computer while depressing the Option key to launch the boot manager.

Verify that the recovery HD was successfully created by booting into it.

Even though CCC 4 can back uprestore recovery partitions, it does have its limits -- namely, Fusion Drives and Core Storage volumes.
