There are some free software available you can search them on google but I do not believe in free software as it will end up messing my computer with virus and spywares and whether it recovers your data intact or not is not guaranteed there are chances that you end up loosing your precious data. So I look for cheap and good software and then i found this brilliant Photos recovery software for mac which can efficiently repair your all corrupted photos on mac. you should evidently use this software to perform recovery operation from any one of different scanning modes and get the list of ‘to be recovered’ files in tree view. In short, this software will give you the preview of these files to let you select the files you think it’s important to recover.
