Step 2: Once the computer boots into the recovery mode, you would have to choose an option from the Utilities menu.
Step 3: Select ‘Disk Utility’ followed by the internal storage disk from the options present on the left hand side. Here the disk is ‘APPLE SSD SD0128F Media’.
Step 4: Click ‘Erase’ that’s visible towards the top of Disk Utility. Check for the following options.
Format: Mac OS Extended (Journaled)
Scheme: GUID Partition Map.
Step 5: Finally, click on the ‘Erase’ button. Later, once everything is deleted, reinstall the operating system once again.
