Pearing 2.0 | OS X High Sierra

Important

Pearing your MacBook is a simple, but permanent process. To prevent the potential for data loss, please make sure to follow the steps below carefully. Pearing makes edits to your operating system's core storage which results in a Macintosh HD that is additively larger.

Create a Time Machine Backup


    Turn OFF


    Boot into Recovery Mode


    Open Terminal

    • From the Menu Bar of the "OSX Utilities Screen", click on Utilities and choose Terminal.

    • how to select Terminal from os x utilities window

      Run DiskUtil

      Use the diskutil list internal command to identify your internal drive and TarDisk.


      Type diskutil list internal in Terminal and press enter/return. You should get results similar to these:


      Diskutil Internal List

      We are looking for two different volumes; Apple_APFS Container and TarDisk.

      Your disks may have different identifiers assigned to them, so please pay attention! In our case disk0s2 corresponds to the Apple_APFS Container, and disk4 to the TarDisk volume.


      Finding your Apple_APFS Container volume should be easy as there should be only one. Meanwhile, TarDisk should have EFI and Apple_HFS volumes as you can see in the picture above..



      Erase the APPLE_APFS Container volume and TARDISK

      Once you have figured out which sections correspond to the Apple_APFS Container and TarDisk, you must erase both of them. So please run the following command:


      diskutil eraseVolume JHFS+ SSD disk0s2

      If you get a message stating "The target disk is in use by APFS as a Physical Store", then run:

      diskutil apfs deleteContainer disk0s2

      Once it's done, you can try running diskutil eraseVolume JHFS+ SSD disk0s2 again.

      Now run this command to erase TarDisk:

      diskutil eraseDisk JHFS+ SSD disk4

      *Please note that your volume identifiers might differ from ours (disk0s2 and disk4), as mentioned in the previous step.


      You will know it is done once you get the following messages after running each of the commands:


      Finished erase on disk0s2 SSD


      Finished erase on disk0s1

      Create a CoreStorage Fusion Group


      Create a CoreStorage Fusion Volume


      Quit Terminal

      • Once completed, quit terminal by clicking the red "X" in the top left hand corner of the Terminal Window.



      Restore from a Time Machine backup

      • Once back to the "OS X Utilities screen". Click Restore From Time Machine Backup.

      • Mac OS X Utilities

        Finished!

        You will be shown how much space you have created by Pearing. Your Macintosh HD will now show two HD volumes, however both volumes will show the combined size of the two.
