Recover Lost Data from System Disk under macOS High Sierra or Later

Magoshare Data Recovery for Mac can help you recover lost data easily and completely. After you upgrade your Mac to macOS 10.13 High Sierra or later, the system does not allow any app to directly scan the system disk drive (startup disk, Mac HD). System Integrity Protection (SIP) is a security feature introduced in Mac Operating System to restrict the access of third-party applications to system disk. If you want to recover lost data, you should: 1. Disable SIP; 2. Restart Magoshare Data Recovery for Mac to scan the system disk; 3. Recover lost data.
