Photo recovery performed on the Mac OS
As with any application saved or loaded onto a Mac computer photo recovery tools must be designed to support that particular OS. Simply put, don’t try to find deleted digital photos on a Mac with a tool built for Windows. Now as obvious as this may sound it might surprise you to learn two things. First, people attempt to load Windows data recovery tools onto Macs all of the time. And second, there are many low quality file recovery tools that are claimed to be capable of Mac file recovery but must be operated from a separate PC.
For photo recovery Mac users obviously will do better using software built expressly for that purpose. These real Mac recovery programs install to your Mac and from your Mac will scan any digital media connected to it. Remember very often common picture file types so as JPEGs are adjusted so as to be archived on your Mac. A photo recovery utility installed on a Windows PC may be able to find a lost JPEG but not one that was saved on a Mac.
