macOS 10.13 High Sierra is using the latest file system – Apple File System (APFS). It doesn’t allow any application to access to the system hard drive (the hard drive where the system is installed). So, no data recovery software can directly scan the system hard drive (also called startup hard drive, boot hard drive, Mac HD, etc) under macOS 10.13 High Sierra. If you want to recover lost data from the system hard drive, you should disable System Integrity Protection (SIP) first and then run the data recovery software.
Do Your Data Recovery for Mac can help you directly recover lost data from other hard drive, USB flash drive, memory card or external device under macOS 10.13 High Sierra. But, if you want to recover lost data from system hard drive under macOS 10.13 High Sierra, just follow the steps below.
