Apple Mac files are cataloged using a system known as the type/creator method. This is in contrast to the Windows system you which uses a file extension. So how then could a Windows data recovery software program recognize and recover accidentally deleted Mac files? Simply put, it could not. Windows data recovery programs will not open and operate on a Mac Computer. But even if they could do it they would not be able to recognize Mac application files.
For Mac data recovery you must use a software program that is a universal application for Mac meaning it will open up a Mac computer. That Mac recovery program must also be able to scan a complete Mac driven internal hard drive and return from that scan Mac type/creator files. The specialized design qualifications of Mac data recovery software are the reason Mac recovery programs cost a bit more than those used to recover lost or damaged files on Windows.
