I recently downloaded the trial version of a photo recovery for Mac software utility. I was extremely disappointed to discover that this particular program was merely a rehash of an earlier version photo recovery Mac operating system software. Before the implementation of Mac OS X it was necessary to access Mac computer hard drives from a data recovery program that was installed on to a Windows based PC and connect it to the Mac hard disk drive by means of cables.
And it should be noted that these programs were only capable of entering a crashed hard disk drive on a Mac and copying visible files. Mac photo recovery programs based on a Windows PC are for the most part unable to recognize file information in areas of that drive marked as available to write new information. It is in these file locations that deleted files reside. So basically this program which claimed to be capable of Mac OS X file recovery was of no value whatsoever.
