Regarding the specific version (7.5) and crack/registration key, I strongly advise against using pirated software or cracks, as they may pose security risks and violate intellectual property laws.
The primary motivation for seeking a cracked version is straightforward: cost. While the free version provides basic functionality, the advanced features — particularly unlimited extraction and iCloud backup access — require a paid license. For individual users who only need the tool occasionally, paying for a license may feel unnecessary.
