Extra Tip: Restore lost data due to the macOS 10.13/10.13.4 High Sierra update
If you forgot to create backups for your Mac data before the macOS 10.13/10.13.4 update, you still have a chance to restore lost data due to the update.
Professional Mac data recovery software - EaseUS Data Recovery Wizard for Mac with Bootable Media allows you to restore all lost data due to a macOS update or for other reasons. Click the tutorial page about how to create bootable media for Mac.
Step 1. Install and run EaseUS Data Recovery Wizard for Mac on another Mac computer, and select "Unbootable Mac > Start".
Step 2. Then, choose a prepared USB drive to create the bootable disc. Select "Next" to start creating the bootable disk.
- The creator will prompt to erase the drive to reallocate the space; then it can write the bootable files to this drive. Please back up all USB files before processing "Eraser".
Step 3. The program starts to create a 2GB space and save the boot files. The rest space on the USB can be still used for storage.
Step 4. Once it completes, please follow the guide to boot the corrupted Mac from the bootable disc and start the recovery. We suggest you restore the data to an external hard drive.
Step 5. After booting the Mac, launch EaseUS Data Recovery Wizard for Mac. Select the disk location (an internal HDD/SSD or a removable storage device) where you lost data and files. Then, this recovery tool will scan for lost files automatically.
Important Note -- if your Mac hard drive uses an APFS file system, you can only use the deep scan option to scan and find all lost data on the drive
