With the help of Amrev recovery software we get back all data until overwritten by new data. If you act quickly, you may be able to successfully recover deleted pictures, videos, songs, emails on your phones, computers , camera or memory card.
I used Amrev Photo Recovery and it will show you how to recover the photos on mac in details. You can try the free trail first to see whether it suits your systems. As for me, it is very easy for me to use. Hope the software can rescue you from this problem too
