Un-Pearing your TarDisk is easy.
Just follow the steps outlined below:


1. Reduce the used disk space on your Macintosh HD to at least 20% below its original size. For example, if your original Macintosh HD size before Pear-ing was 121GB, you must make sure that your current system has 97GB or less on it now.


2. Turn off file Vault.

3. Create a Time Machine backup and insure that you have backed up your data. This step is critical for the un-Pearing process. For added protection, in addition to the TimeMachine Backup, feel free to use an online backup as well. 

4. Turn off your computer.

5. Slide your TarDisk out.

6. With the TarDisk Removed, restart your computer into Recovery Mode by holding down  Command (⌘) + R keys while the computer turns on. You will see a window here like the below. Then enter "Disk Utility" and click continue. 
7. Different Variations of OSx now present different screen choices. To proceed, select your Operating System. For Yosemite (or older) proceed to step 8 below, for El Captain (or newer) click  here.
OSx Yosemite (or older) or OSx El Capitan (or newer)

8. For OSx Yosemite (or older), the window should look like the following screen shot. Once you're here click "Macintosh HD" which will be in Red font. (If you find that the Disk Utility on your computer does not look like the image below, and instead looks like this, you are running El Captain and need to re-read step 7.)

9. A dialogue like the following will come up. Click "Fix."

10. You should see something like the following while the disk is being fixed:

11. Once completed make sure to check that the newly repaired disk is healthy by clicking "Verify Disk."

12. If the fix worked you should get a green result that reads: "The volume Macintosh HD appears to be OK." 

13. Exit Disk Utility to bring you back to the Safe Mode Boot "OS X Utilities screen." Click "Restore From Time Machine Backup".

14. Click "Continue" and follow the restore process.

15. Select your newly repaired Macintosh HD. Note that the "space available" is the size of your SSD without Pear. 

16. You will see the following dialog. "In order to restore from a Time Machine back up, all current data will be erased, to make way for your backed up data". Click "Continue".

17. The HD will be erased to make space for the data recoded in the TimeMachine Backup.

18. Then the restore process will begin. It can take some time, so let it run without interrupting the process.
 Make sure your computer is plugged into a power supply. 

That's it, you are done!
      A few notes:
        1. This process removes your Pear'ed TarDisk from your system. 
        2. If you would like to use TarDisk again, you will need to activate it by deleting the EFI partition. Please see our FAQ for more information on how to do this here.
        3. If you would like to Pear your TarDisk to your system again, you will need to activate the TarDisk as mentioned in the previous step. Although our Terms of Service specify a one-time-use license, we are happy to help you Pear a second time! Send an email to us with the subject line: "Pear after un-Pear" and the following information;
      • Your MacBook's serial number.
      • Your original receipt. (The email confirmation of your order)
      • The following written statement; "I acknowledge that Pear-ing my machine a second time, removes safety checks which can potential introduce unforeseen errors."
      • If you need to restore a Time Machine backup which is larger than your original size'd SSD, (ex: your Peared machine was 512gb and after un-pearing you machine is now 256gb) doing so is possible! When you start up you un-peared MacBook, (step 13) select "install a new copy of osx". When your macbook starts up, you will be asked it you want to import data. Say yes, and follow the prompts and point to your Time Machine backup as the source. You will get to a screen that shows your user account and a bunch of checkboxes where you select what you want to import. When you get to that screen select your user account and below that you can uncheck the big folders like Music and Photos so those don't get moved over. After the migration and after you have restarted into your new MacBook, manually go back into the TM backup and restore those two folders to an external drive.
